I have a remotely mounted O2 tank that needs monitoring. I have an approved tank pressure sensor with a 0-5 v output that I'd like to hook up to the EMS. Since this kind of sensor isn't mentioned in the manual I just wanted to be sure there was nothing special about connecting it to one of the open unused pins in the EMS. Would there be a preferred group of inputs that would be desirable to use? Also, there is another brand of sensor with a 4 - 20 mA profile. Which would be preferable?

The 0-5V works. You can make up a special sensor definition. If you have the formula for volts to pressure I can help you with the sensor definition. It may be limited to the Enhanced General Purpose pins but there are four pins available.

Mountain High Oxygen has a sensor that looks like it could work. I have also seen a number of other companies, among them Ashcroft (look at their G2 sensor) which appear to be able to do this. My O2 regulator has a gauge with a 1/4 in NPT thread, and that port is where the transducer goes. It's just a matter of wiring the sensor to the EMS.

My original post was just seeking ideas on which EMS input it should go. MMarion is suggesting it's a class C sensor, and that seems right to me. I may just have my A&P figure all this out. Since the cylinder is behind me in the baggage area and I can't see it, this is a good way to track usage.
