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...

Purchased item to build a pressure interface for an automotive o-scope. Bench tests ok, but have not put it in service as of this time, thus the 4 star rating.

Works well. The cord is too short.

Although physically a solidly built unit, the electrical portion of this sensor is terrible. Tried both the 10PSI and 30PSI versions of this in a low pressure water sensing application (0-7PSI). First unit failed after 3 weeks (no output). Second unit failed during bench testing prior to even being deployed (output stuck at 4.5V regardless of pressure). As an electrical engineer of some 35 years, I seriously question the electrical design of these sensors. 100% failure rate means they are effectively worthless.

These will not thread into an NPT fitting more than a thread or two. They also are not tapered threads. Make sure you know what you’re buying. They do work though

I bought two to monitor low air pressure, neither worked.

the pressure sensor only worked for 3 months before giving up, and was operated well below it's pressure threshold
