<div dir="ltr"><div>Thanks Alan,</div><div>Yes much of the stuff in my catalogue is dedicated to SCUBA gas mixing and high pressure oxygen (and there is a bunch more about to be added).  A couple of items are from Undersea UK and if you ever want some stuff from there let me know and we might consolidate shipping.  For the record, my HP oxygen digital gauge is US$183 compared to US$208 for the Undersea one - they have great stuff but getting it down here is sometimes not cost-effective (and their standard thread is 1/4" BSPP with O ring, whereas I prefer 1/4" NPT).</div><div><br></div><div>Actually while on the subject of pressure monitoring, I've nearly finished development and production of a couple of new products that may be of interest to psubbers - an "Oxygen Watchdog" and "Pressure Watchdog".  These are self-contained panel-mount kits with sensor, display/controller and 2 independent relay outputs.  They read and display the O2 percent or cylinder pressure, and the controller can be set to trigger/release the relays under various circumstances (low setpoint, high setpoint, too far from a middle setpoint, etc.).</div><div><br></div><div>They are intended for SCUBA compressors and mixing systems, but would do well (with perhaps a few minor modifications) if you want a standalone/PLC-independent alarm system in a PSUB.  A couple of pictures of the prototypes are below.</div><div><br></div><div>If anyone is interested in a kit, (or just bits of it) then let me know.  They are light enough that shipping anywhere in the world will be pretty reasonable.</div><div><br></div><div>Cheers,</div><div>Steve</div><div><br></div><div><br></div><div><img width="471" height="265" alt="Inline image 2" src="cid:ii_1581d1903b613eba"><img width="471" height="265" alt="Inline image 3" src="cid:ii_1581d1a7a06f866f"></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Tue, Nov 1, 2016 at 8:21 AM, Alan James via Personal_Submersibles <span dir="ltr"><<a href="mailto:personal_submersibles@psubs.org" target="_blank">personal_submersibles@psubs.org</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div><div style="color:rgb(0,0,0);font-family:HelveticaNeue,Helvetica Neue,Helvetica,Arial,Lucida Grande,sans-serif;font-size:16px;background-color:rgb(255,255,255)"><div id="m_2835140993798000624yui_3_16_0_ym19_1_1477944393544_5903"><span>Steve,</span></div><div id="m_2835140993798000624yui_3_16_0_ym19_1_1477944393544_5932"><span id="m_2835140993798000624yui_3_16_0_ym19_1_1477944393544_6023">just had a look at your 2016 catalogue.</span></div><div id="m_2835140993798000624yui_3_16_0_ym19_1_1477944393544_5933" dir="ltr"><span id="m_2835140993798000624yui_3_16_0_ym19_1_1477944393544_6022"><a id="m_2835140993798000624yui_3_16_0_ym19_1_1477944393544_6021" href="http://www.tfmengineering.com.au/TFM_Engineering_Catalogue_2016-03.pdf" target="_blank">http://www.tfmengineering.com.<wbr>au/TFM_Engineering_Catalogue_<wbr>2016-03.pdf</a></span></div><div id="m_2835140993798000624yui_3_16_0_ym19_1_1477944393544_5931"><span id="m_2835140993798000624yui_3_16_0_ym19_1_1477944393544_5930">Wow, you've got a lot of gear I haven't seen before.</span></div><div id="m_2835140993798000624yui_3_16_0_ym19_1_1477944393544_6009"><span>Alan</span></div><div id="m_2835140993798000624yui_3_16_0_ym19_1_1477944393544_6050"><span></span> </div><div id="m_2835140993798000624yui_3_16_0_ym19_1_1477944393544_6001"><span></span> </div><div id="m_2835140993798000624yui_3_16_0_ym19_1_1477944393544_5958"><span></span> </div><div class="m_2835140993798000624qtdSeparateBR" id="m_2835140993798000624yui_3_16_0_ym19_1_1477944393544_5904"><br><br></div><div class="m_2835140993798000624yahoo_quoted" id="m_2835140993798000624yui_3_16_0_ym19_1_1477944393544_5908" style="display:block">  <div id="m_2835140993798000624yui_3_16_0_ym19_1_1477944393544_5907" style="font-family:HelveticaNeue,Helvetica Neue,Helvetica,Arial,Lucida Grande,sans-serif;font-size:16px"> <div id="m_2835140993798000624yui_3_16_0_ym19_1_1477944393544_5906" style="font-family:HelveticaNeue,Helvetica Neue,Helvetica,Arial,Lucida Grande,sans-serif;font-size:16px"> <div id="m_2835140993798000624yui_3_16_0_ym19_1_1477944393544_5905" dir="ltr"> <font id="m_2835140993798000624yui_3_16_0_ym19_1_1477944393544_5913" face="Arial" size="2"><span> <hr size="1"> <b><span style="font-weight:bold">From:</span></b> Stephen Fordyce via Personal_Submersibles <<a href="mailto:personal_submersibles@psubs.org" target="_blank">personal_submersibles@psubs.<wbr>org</a>><br> <b><span style="font-weight:bold">To:</span></b> Personal Submersibles General Discussion <<a href="mailto:personal_submersibles@psubs.org" target="_blank">personal_submersibles@psubs.<wbr>org</a>> <br> </span><b><span style="font-weight:bold">Sent:</span></b> Monday, October 31, 2016 4:53 PM<span><br> <b><span style="font-weight:bold">Subject:</span></b> Re: [PSUBS-MAILIST] Electr
