Honeywell PX2 100 psi (~7bar) linear gas/oil pressure sensor.
Original Honeywell sensor, much more durable than the type of sensor sold earlier, which was strictly for gas/oil (and actually had higher failure rate with fuel). Refer to PX2AN2XX100PSAAX datasheet and own tests (controlled+safe conditions) for suitability for an application.
Pinout, Looking into the sensor:
- top-center (green): 0.5-4.5V pressure signal output for 0-100 psi (slope appr: 4V / 7 bar, or 1V/25psi)
- bottom-left (red) +5V supply (normally <30mA)
- bottom-right (yellow) GND
See VemsDisplay calibration (similar in VemsTune)
