Does not work. good for me

I ordered this device to monitor output pressure of a pump running between 30 to 50 PSI. That does not matter. I could not get the device to work. It's output voltage is a constant 4.9 when run on a 5.1 supply. This reading holds true even on a bench hooked to a 100psi air compressor. I even tested to see if this was a constant current device and that out put did not change by more than one milliamp across the pressure range.

Pros

Protetcion Function: It has complete surge voltage protection function

Cons

Not suitable for use with non-1/8" NPT threads
