Great sensor for monitoring gas/air pressures.I use this to sense the pressure in my air compressor's tank, and sound a gentle warning before the compressor kicks on. Trying to save the stress on my heart being startled so often.1/4" NPT threads make connecting to existing air system easy, but the 30 PSI upper limit means it does need to live on the regulated side.

This sensor seems very accurate for monitoring water pressure. I'm doing this at a community water plant so the staff can check the plant status from home. This prevents them from making middle-of-the-night trips to see if things are running.I set up a homeassistant server and put this one an esp32 using esphome. This works very well and allows me to remotely troubleshoot and update the system - since my home is a couple of hours away from the water plant.I heartily recommend home assistant and esphome for this. It's cheap, it's easy, and it's reliable. The equivalent commercial system is thousands of dollars and has a subscription fee. Though home assistant has a subscription for remote access, it's cheap, and the components for this project were under $400.This sensor works with the 3.3V provided by an esp32. And the analog sensor has enough resolution for this task. The results correlate very well with the expensive monitoring system they have that's not cloud-enabled.Before this, we had used Particle and Ubidots and created a similar system (which has been running since 2017). But IOT cloud systems have gotten very expensive lately and are persnickety, so we are self-hosting (with a home assistant).

This transducer appears to be reasonably accurate. Meets my requirements to measure fuel pressure.

I ordered two of these, supposedly same range.There are no markings on them whatsoever, so no idea what max pressure they had.So I rigged a 3m watercolumn to measure accuracy and an Arduino to test them side by side, in 50cm increments.Unit 1: 50cm = 50 counts. exact across 3m (330)Unit 2: 50cm = 30 counts. About 1 count off linearity across 3m (215).It's important to let the units stabilize to achieve this linearity. I had started the first sequence immediately after powering up the unit and there was drift and nonlinearity...I conclude that unit #1 has a full range of about 10m, (15psi/1 bar), whereas unit #2 is twice that, 20m (30psi/2 bar).Why they sent me two different ones? Without any markings on the unit, they probably don't know either.I don't yet know, how well these are going to perform in my application, i.e. monitoring my rain water tank levels...An additional, much more troublesome issue is the isolation of the housing from the sensor connections.One unit shows completely Open, the other has its resistance varying from as little as 40kOhm to 5MOhm... Why do you care? Because if you are measuring a conductive medium like water, you need to ground the housing. It doesn't affect the first unit, but the second unit pulls the output to 5V!!!I have 5 units total, from a couple of different suppliers... 2/5 are isolated, 3/5 are not and as a result drifting when grounded...So, testing on the lab bench is going to produce a nasty surprise, once you install the sensor into your application...
