It can only handle one O2 input, and the control is limited by controller settings - it's an off-the-shelf item and not fully programmable like a PLC. Good for an independent backup or alarm. As a primary system it could be made to work but would require a thoughtful setup. Eventually I do plan to make a rebreather controller (for the rebreather I'm designing) which would be perfect (many O2 cell inputs and a solenoid or two output), but that's a while away! A key thing to consider in automatic oxygen adding is placement of sensors, natural mixing of the air and sufficient time delay in the control system to get meaningful feedback before the next oxygen injection (Ie. rebreather controllers squirt a little bit of oxygen in, wait a few seconds for it to mix, and then measure, and squirt in more accordingly). Cheers, Steve PS: I also have some M12 plated brass Blue Globe cable glands if you find yourself short a couple - very hard to get down here.

Maybe Phil will chime in with details. The system uses his O2 bellow add valve which bleeds 100% O2 into the cabin based on a drop in barometric pressure from the time the hatch was closed. At the time of launch SOP calls for them to pull a slight vacuum in the boat to assure the hatch o-ring is sealed and to make it easier to dog the hatch latches. The last spec I saw on the DW 2000, the endurance is 80 hours. There are two scrubbers (one redundant), each containing 12 lbs of SodaSorb HP. There is also a BIBS system. They have O2 and CO2 monitors. The O2 bottles are externally mounted. Since his life support endurance is 80 hours, I he should have in excess of 80 scf of O2. I don?t know how the Sodasorb is set up to filter, axial or radially nor do I know the type of blower he is using in the scrubbers. As long as the blower on the scrubber is strong enough to circulate the cabin air through the filter every hour or so, the 100% O2 that is blead into the cabin will mix with the cabin air due to molecular diffusion. I believe he uses the same basic life support system on all his boats. Phil?s paper on Life support http://www.psubs.org/design/lifesupport/lifesupport.pdf is a good read on how his bellows add system work and life support in general. When Phil let the PSub members dive his subs at the Vancouver PSub Convention, I remember seeing the scrubbers and noting they were compact but I was more focused on diving the DW 2000 so did not pay too much attention to the scrubber design. The two key things I would like to know is what is the make and model of the blower he uses and is the filter oriented to pull the cabin air radially or axially through the Sodasorb HP.

The one I linked to is there top of the line, twin channel speed controller. It will supply 2 DC motors up to 60A EACH. They also have lower current rated ones. They come with all of the bells and whistles. You can do linear or exponential control through 2 channels of mixed or unmixed RC or 2 channels of analog 0-5 input. I've used these controllers extensively for a while now. They are really neat. The big issue is that it doesn't do 36V systems.

That's the one your pressure gauge runs off. Even though the hole is literally a pin prick, I was getting at least 2 liters a second flow out of it. I am building a similar sized sub to Cliff's R300 & a leak like that, apart from increasing the pressure massively, would be hazardous if it was O2. In 4 minutes I could have 70% O2 based on an air volume in the sub of 250 liters. I think I'll go for a pressure gauge outside my view port or try potting a digital pressure gauge & just send the wires through a penetrator.

A key thing to consider in automatic oxygen adding is placement of sensors, natural mixing of the air and sufficient time delay in the control system to get meaningful feedback before the next oxygen injection (Ie. rebreather controllers squirt a little bit of oxygen in, wait a few seconds for it to mix, and then measure, and squirt in more accordingly).

Mainly because I want to keep everything as small as possible. With your O2 unit it looks like you could have it doing similar; turn on a solenoid to top up the O2 beyond what is flowing in from a pre-set valve.

A lot cheaper than I thought. However looking at the data on their standard XS4 series, the "trip" flow on 3000psi is 250 cubic ft per minute or 116 litres per second. I had measured roughly 2 litres per second coming out of my 1st stage high pressure port. They do say they have smaller springs for tripping at a lower flow but it might be a big step to get to what I want ie. tripping with virtually no flow. For me I am leaning toward the option of potting the electronic gauge that Steve suggested & having wires through the hull to a plc. plus have contents gauges within view of my dome.

I can treat it like a round scrubber with a fan at the end with an air space between the fan and absorbent bed. I am just not sure if it is axial because the scrubber seems to be a mesh body. I also did not pay much attention on my tour, I was a bit overwhelmed. Hank On Tuesday, November 1, 2016 2:13 PM, Cliff Redus via Personal_Submersibles wrote: Hank, don?t know all the detail on the Deepworker 2000 but will convey what I know. Maybe Phil will chime in with details. The system uses his O2 bellow add valve which bleeds 100% O2 into the cabin based on a drop in barometric pressure from the time the hatch was closed. At the time of launch SOP calls for them to pull a slight vacuum in the boat to assure the hatch o-ring is sealed and to make it easier to dog the hatch latches. The last spec I saw on the DW 2000, the endurance is 80 hours. There are two scrubbers (one redundant), each containing 12 lbs of SodaSorb HP. There is also a BIBS system. They have O2 and CO2 monitors. The O2 bottles are externally mounted. Since his life support endurance is 80 hours, I he should have in excess of 80 scf of O2. I don?t know how the Sodasorb is set up to filter, axial or radially nor do I know the type of blower he is using in the scrubbers. As long as the blower on the scrubber is strong enough to circulate the cabin air through the filter every hour or so, the 100% O2 that is blead into the cabin will mix with the cabin air due to molecular diffusion. I believe he uses the same basic life support system on all his boats. Phil?s paper on Life support http://www.psubs.org/design/lifesupport/lifesupport.pdf is a good read on how his bellows add system work and life support in general. When Phil let the PSub members dive his subs at the Vancouver PSub Convention, I remember seeing the scrubbers and noting they were compact but I was more focused on diving the DW 2000 so did not pay too much attention to the scrubber design.

I also did not pay much attention on my tour, I was a bit overwhelmed.Hank On Tuesday, November 1, 2016 2:13 PM, Cliff Redus via Personal_Submersibles wrote: Hank, don?t know all the detail on the Deepworker 2000 but will convey what I know.? Maybe Phil will chime in with details.The system uses his O2 bellow add valve which bleeds 100% O2 into the cabin based on a drop in barometric pressure from the time the hatch was closed.? At the time of launch SOP calls for them to pull a slight vacuum in the boat to assure the hatch o-ring is sealed and to make it easier to dog the hatch latches.? The last spec I saw on the DW 2000, the endurance is 80 hours. There are two scrubbers (one redundant), each containing 12 lbs of SodaSorb HP. There is also a BIBS system.? They have O2 and CO2 monitors.? The O2 bottles are externally mounted.? Since his life support endurance is 80 hours, I he should have in excess of 80 scf of O2.? I don?t know how the Sodasorb is set up to filter, axial or radially nor do I know the type of blower he is using in the scrubbers.? As long as the blower on the scrubber is strong enough to circulate the cabin air through the filter every hour or so, the 100% O2 that is blead into the cabin will mix with the cabin air due to molecular diffusion.I believe he uses the same basic life support system on all his boats.? Phil?s paper on Life support http://www.psubs.org/design/lifesupport/lifesupport.pdf is a good read on how his bellows add system work and life support in general.When Phil let the PSub members dive his subs at the Vancouver PSub Convention, I remember seeing the scrubbers and noting they were compact but I was more focused on diving the DW 2000 so did not pay too much attention to the scrubber design.? The two key things I would like to know is what is the make and model of the blower he uses and is the filter oriented to pull the cabin air radially or axially through the Sodasorb HP.

Been working on two Psub projects. The first is working with a local high school on a modified K350 build. I spent the last two month detailing the boat with Autodesk Inventor and now have a pretty complete package of drawings and specs for a modern K-350. The original K-350 plans are fairly basic and required quite a bit of reading between the lines. Changes I made to the original K-350 design were more battery capacity and larger and wider apart battery pods to accommodate, Minn Kota 101 based Kort thrusters like I use for my boat, and totally new electronics including PLC and HMI, full life support including BIBS and added two more viewports. The MBT system has been totally changed. I am using two of Hugh Fulton's pneumatic pancake style valves to blow the MBTs and am using Swagelok 3-Way valves to operate the MBT and VBT. Team is waiting on final budget approval before we pull the trigger on the project. Team has already received $15K in equipment donations. On the R300, I am in the process of switching control of the compass/pitch/roll sensor which uses RS232 serial communication from an RS232 port on the PLC base to a dedicated PLC coprocessor. I have had some intermittency issues with this sensor over the years and I am trying this to see if this solves the problem. What I really need is an O Scope that has RS232 investigation feature. With the work on the K-350 project, I have just not had any spare time on my boat. Hope to rectify that shortly. Got a consulting job I have to knock out next week in Oklahoma City then I am free for the rest of the year to play with psubs.

That said, I'm amazing someone hasn't shut it down for being "too dangerous". I haven't looked at the K-boat plans for a while, but I also recall some reading between the lines - I had considered converting them to CAD to make for a starting point for alterations but never got to around it. Perhaps you would considering making them available (with a disclaimer, etc.) for distribution/sale with the K-boat plans on the PSUBS website.

Strain gauges and foil pressure transducers thus work the same way. If you need an industry standard output (i.e. 0-10V or 4-20 mA), your transducer must incorporate an appropriate signal amplifier.

The difficult bit to get the Chinese suppliers to understand is oxygen cleaning - and that sort of thing really needs to be cleaned before assembly, and during any subsequent testing/calibration process. Ie. they are likely to use water (or maybe even oil - many standard pressure gauges are also tested on oil by default) to test, which will leave residue that could be very scary in oxygen service.

That's a huge project updating K350 plans & overseeing the student build. I know we have talked about a plan overhaul in the past. I guess the next step is building it & then considering the option of replacing the existing plans. As I remember, the current plans called for components that no longer existed, & had a hard ballast design that would explode if it saw full tank pressure. Look forward to seeing a video of the R300 diving with it's new modifications.

The first is working with a local high school on a modified K350 build. I spent the last two month detailing the boat with Autodesk Inventor and now have a pretty complete package of drawings and specs for a modern K-350. The original K-350 plans are fairly basic and required quite a bit of reading between the lines. Changes I made to the original K-350 design were more battery capacity and larger and wider apart battery pods to accommodate, Minn Kota 101 based Kort thrusters like I use for my boat, and totally new electronics including PLC and HMI, full life support including BIBS and added two more viewports. The MBT system has been totally changed. I am using two of Hugh Fulton's pneumatic pancake style valves to blow the MBTs and am using Swagelok 3-Way valves to operate the MBT and VBT. Team is waiting on final budget approval before we pull the trigger on the project. Team has already received $15K in equipment donations. > > On the R300, I am in the process of switching control of the compass/pitch/roll sensor which uses RS232 serial communication from an RS232 port on the PLC base to a dedicated PLC coprocessor. I have had some intermittency issues with this sensor over the years and I am trying this to see if this solves the problem. What I really need is an O Scope that has RS232 investigation feature. With the work on the K-350 project, I have just not had any spare time on my boat. Hope to rectify that shortly. Got a consulting job I have to knock out next week in Oklahoma City then I am free for the rest of the year to play with psubs. > > Regards > > Cliff > > >> On Thu, Nov 3, 2016 at 3:15 PM, Alan James via Personal_Submersibles wrote: >> Thanks Cliff, >> no doubt I'll have more questions when I start >> trying to nail down what PLC, HMI & software. >> Have just ordered 2 of those digital to 0-5V converters >> for my remote system.

I have about 12 quotes, 1 as low as US$37- . I think it was on a quantity of 5. I am now asking them if they are able to be O2 cleaned with alcohol.

Q-Sub is a totally new concept/boat with lots of new systems to sort out. This K350 project is mostly cleaning up drawings, updating part sourcing and a bit of new work on thrusters and electronics. If I lived in New Zealand, my second home would be in your shop working with you on your Q-Sub. On my bucket list is to dive in your boat when she is done.

It will be interesting so see which faction wins out. If the "too dangerous" faction wins, I may end up building the boat myself just for fun! As Carsten says, everyone needs a least two Psubs! As to selling these modified K-350 plans, not sure what Jon's position on this would be as he/Psubs has sole rights to distribute original K-350 plans. At some point I might pick his brain on what we could do with these plans. For now I just want to build the boat off these plans!

In the original plan, the VBT blow, vent and air supply valves are manual with air supply from HP side of internally located scuba tanks. So if operator took a stupid pill, he could rupture the tank by initiating a VBT blow and forgetting to open either the vent for flood valves. To mitigate this issue on the new build, I use the system I use on the R300 which is to use regulated air from scuba LP port. With the regulator I use, the operator can set the delta air pressure above ambient water pressure. On my boat I use 75 psi above ambient. If it takes to long to blow the MBT, I can up this valve. To give more room in the interior of the boat, I moved the two 100 scf scuba tanks outside the pressure hull under the aft MBT in the area that in the original plans has the main propulsion motor. This space is open now that I removed this motor and have two horizontal aft Minn-Kota 101 thrusters for main propulsion and yaw control. An alternative solution would be to stay with the HP air to blow tanks but install a pressure relief valve on the VBT tank. An advantage to using the external scuba tanks with scuba regulator is that I hang a BIBS system for both the pilot and passenger off the LP air supply.

That hard ballast tank blowing up could cause a fatality. You have to factor in an operator taking a "silly pill". I made the cardinal mistake of trying to dive with the hatch un-dogged. With all the harassment from inquisitive people at the boat ramp & onlookers it through my preparation. I motored out with the hatch unlatched because it was hot, then in my intense concentration on what I should do next, I forgot about the hatch :( Got a lot of water in but didn't go down as I didn't have enough lead at that stage. I wonder what parts Psubbers might have lying round if you made a list of your teams required components.

It is probably more cost effective to use an o-ring sealed adapter to NPT (such as a Swagelok SS-4-SAE-7-4) and an industry standard male NPT transducer, than trying to source a transducer with the o-ring sealed straight thread fitting.

Ports on the regs are generally 3/8? . Female thread lengths for 3/8?, 7/16? ?? 9/16? are 10mm, 11.5, 11.5, 12.7 resp. The male threads are shorter. All in parker or Swagelok literature. Those ports are fine in the small sizes up to about 1-1/16?. Smaller sizes are good for over 6,000 psi and up to approx. 9,000 psi. in SS. Brass is not so good Think of it as a ratio of area to circumference. We don?t like doing burst tests on Threads of 1-5/16? as the thread stretches and then the o-ring pops out at around 20,000 psi, which negates the test. Generally 6 threads on most sizes is sufficient.

I guess it ?would allow ?for a bit of expansion.I did some calculations on the hose & it may not squeeze in untilat least 100ft. As the seals are only rated to 30ft that means theywould fail before you had any pressure compensation. "However"if you pre-compress the hose with a metal band to make it out of round, it solves the problem.?cliff is using a regulator with relieving function to compensate.You could use this for air or oil, & it would take up any expansion.I believe (but could be wrong) that the 101 has 2 lip seals.To me this is a problem because one of the two of them will fail.There will be 1atm of pressure between the seals until one sealfails. I am not sure what Cliff did about this, he did?a lot of workon the Minn kotta 101 recently.Cheers Alan From: Rick Patton via Personal_Submersibles To: Personal Submersibles General Discussion Sent: Monday, November 7, 2016 10:20 AM Subject: Re: [PSUBS-MAILIST] electrical pass-thru Apparently I am not able to post directly to the group so I'll have to piggyback this thread with a couple of questions for now until I can figure out what's going on.

I guess it ?would allow ?for a bit of expansion.I did some calculations on the hose & it may not squeeze in untilat least 100ft. As the seals are only rated to 30ft that means theywould fail before you had any pressure compensation. "However"if you pre-compress the hose with a metal band to make it out of round, it solves the problem.?cliff is using a regulator with relieving function to compensate.You could use this for air or oil, & it would take up any expansion.I believe (but could be wrong) that the 101 has 2 lip seals.To me this is a problem because one of the two of them will fail.There will be 1atm of pressure between the seals until one sealfails. I am not sure what Cliff did about this, he did?a lot of workon the Minn kotta 101 recently.Cheers Alan From: Rick Patton via Personal_Submersibles To: Personal Submersibles General Discussion Sent: Monday, November 7, 2016 10:20 AM Subject: Re: [PSUBS-MAILIST] electrical pass-thru Apparently I am not able to post directly to the group so I'll have to piggyback this thread with a couple of questions for now until I can figure out what's going on. I am ready to start compensating my Minn-Kota motors and as I understand it from the group, a bladder and or tubing is needed to allow for expansion of the oil when it gets hot. Was wondering if this was based on theory or did someone in the past not do the tubing and have the O ring spit out? I wouldn't think that the tubing would be flexible enough to allow for expansion. I had copied a post of someone who had done it awhile back and they had said that they had drilled a 1/8" hole in the motor housing which seems quite small and was wondering if 1/4" might be better?? also, *For those using Minn-Kota motors, what are you using for a prop tip to hull distance? * The length of rod that protrudes inside the hull ( thruster handle ) * Could I use something like a Schedule 80 ss pipe instead of solid ss round stock boarded out to accept the wires from the thruster? * What size copper rod should I use to equal 10 gauge wire to carry the power from the thruster to inside the sub?

Functionally they are comparable. I prefer the Sofnolime product, but it may not be worth the extra expense if there is a significant difference. I'm pretty sure you can source either in Canada, just not necessarily locally.

I thought I would give everyone an update on Pisces VI. The personnel sphere has been completely painted and restored, the vehicle is completely apart and the design direction has been selected. The next steps are to restore the frame and the VBT's, fabricate the personnel cage, as well as data gathering for what thrusters, sonar, underwater comms, batteries, locator, and nav equipment we will be using. We plan to have this all done by the end of the year. The next steps after the beginning of the year will be to plan out the personnel sphere lay out and put it together as well as finalize the weights and balances. Our design will keep the similar Pisces shape but be only 18' long and weigh around the 15,000 lb area.

Thus far I've installed an acoustic system, OTS channel A compatible system and just scored two(!) Subsea-Import ScubaPhone 3km range surface systems for next to nothing. I'm really hoping they're each set to that company's standard frequency as they are from two different sources. To the later I'll modify one to fit in Harold like I did the old Soniwave Surface unit. Ask Alec about it. It came out really well. Anyway, for the Subsea systems, I'll need to buy a transducer for one of them. Geez the high end stuff is pricey.

The unit you re-packaged with a new enclosure certainly looks like it belongs in a submarine. To keep up with the Joneses, I'll have to control my cabin lights with a big switch under a red protective cover labeled "INITIATE SELF-DESTRUCT COUNTDOWN." No, seriously, that was a nice job and I'm looking forward to seeing Harold diving again.
