Eyourlife Universal 80PSI Pressure Transducer Sender Solenoid for Oil Fuel Gas Air Water F6

If I could do zero stars i would :-).Failed after 12 hours usageGot the unit yesterday for a Arduino project I am working - monitoring water flow and pressure. Unit worked fine last night after I installed it - reading 72psi +/- 2 psi (yes it is noisy - but I can filter sufficiently in F/W). This morning - it was reading 45psi +/-5psi - got my mechanical sprinkler pressure gauge out and had my normal 70 psi and no fluctuations. Odd said I - but thought maybe I had a loose connection or such - but nothing manifested. So went with it planning to re-calibrate it later. Well 4 hours later it is showing 112psi (5v). It is jammed solid at that value - no amount of playing - re-powering - or such recovered it. In short - it was dead. Or is that dead-short to +5 - Haha.Anyway - a large disappointment. And from the reviews - this does seems to be a common failure. Given it was running off the Arduino 5v regulator and all the other items are happy - I must assume that it has just failed and is obviously a poor quality/design.

Well I bought three transducers 30 psi,100 psi and a 500 psi. I have not received the 30 psi yet but the 100 psi failed the first time using testing fuel pressure 60 psi. The 500 psi also failed the first time measuring cylinder head pressure 180 psi. Needless to say I bet the 30 psi will also fail. most likely the first time I use it. I wired it correctly with a 5v reference. I know they are cheep however THE FIRST TIME!!..Well they sent me replacment and they nBoth seem to work well. They will calibrate with my snap-on labscope they gave g8r waveforms as long as you have the filter setting on. The review was a 1 🌟 could have been 5 if I didn't get duds.

Worked well at first but only lasted about 2 weeks using methonal. Just don't think it can hold up to the fuel.

It's been a year and a half since I bought my first transducer here. Yup, it took a dump. But so what? I use it in a tough app: graphing running internal combustion engine pressure, where it takes hits of 70 to 120 psi over 500 times a minute. Even the best built units have a low life expectancy in this environment.Now face it: in the real-world, small-business battles within this global economy, "Made in the USA" is no longer feasible. To replace my busted Vetronix transducer... well, it's obsolete now. Bosch bought Vetronix and their unit costs $400.00! This little $18.00 gem looks identical to the original Vetronix unit, and as the photos show, it's tough to tell the difference.So I'm back, buying two this time so I won't be dead in the hole when the next one craps out.$54.00 for maybe 5 years of service? Yeah, that's 1 star per year Jack!

Dead right out of the box.... verified I had 12 volts feeding it, and a good ground. 0 volts coming from the signal wire.Well since I killed the first sensor per my above comment, Fed a 5V sensor 12V. I figured I'd try a second sensor. I gave the sensor exactly 5V on the supply and i'm seeing roughly a 20% error after 3 to 4 hours of total run time. I am using this sensor to monitor fuel pressure electronically on my dash. I have a mechanical gauge under the hood and this sensor will read around 44psi while the mechanical gauge will show 55-58psi. So given that the sensor is useless, I left my rating at 1 star.
