I would have thought you'd have to mount it some distance from all that steel either vertically like Gary's or horizontally as David proposes. Possibly a greater consideration is the distance from any motors and how you shield them from that interference. </div><div>Jim<br><br>Sent from my iPhone</div><div><br>On Aug 6, 2015, at 11:18 AM, Cliff Redus via Personal_Submersibles <<a href="mailto:personal_submersibles@psubs.org">personal_submersibles@psubs.org</a>> wrote:<br><br></div><blockquote type="cite"><div><div dir="ltr"><div>David, I use a OS5000-S Solid State Tilt Compensated 3 Axis Digital Compass (Serial) from <a href="http://www.ocean-server.com/compass.html">www.ocean-server.com/compass.html</a> . As this will not work in a steel pressure hull, I designed a 1-atm pod that contains the sensor out 6061-T6 and anodized it. This is mounted out side the pressure hull but inside my FRP shell cover. I have been happy with its performance. It sends a RS-232 signal in ASCII that contains the boat heading, roll and pitch angle as well as the water temperature. In the PLC, I have ladder logic that parses the string and converts these into real variables that are display on the HMI both graphically and as text. these sensors cost $325. There only a good idea if you are using a PLC that has a spare serial communication port. <br><br></div><div><br></div><div>Cliff</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Thu, Aug 6, 2015 at 1:17 AM, David Colombo 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"><p dir="ltr">Bought on Ebay. $49 delivered.

I think it could work quite nicely if I can extend the length of wire from sensor to the display. Any thoughts about this. The sensor is about 1" cubed and has a lead with six wires into the display. Its a 12v unit and the power input is on the display itself. So before I tear it apart, I thought I would put it out there on the possibility and how to determine the appropriate wire gauge size. I will want to extend the pigtail to around 10 feet.<div><br><div><div><div dir="ltr"><div>Best Regards,<br>David Colombo<br><img width="200" height="110" src="http://static.squarespace.com/static/533310a9e4b0fba62008a464/t/5339c1f2e4b041bac4e25d1b/1396294132055/?format=500w"><br>804 College Ave<br>Santa Rosa, CA. 95404<br><a href="tel:%28707%29%20536-1424" target="_blank" value="+17075361424">(707) 536-1424</a><br><a href="http://www.SeaQuestor.com" target="_blank">www.SeaQuestor.com</a><br><br></div></div></div></div>
