The sensor is made from one piece of Stainless Steel with a plastic 3pin Packard GT150 circular connector and 1/8″ -27 NPT threads.
Commonly used for measuring, Fuel pressure, Coolant pressure and other liquids up to 5 Bar (75psi). Measures “Gauge pressure” which means it’s zero-referenced against ambient air pressure.
Sensor is feed with 5volt supply and gives 0,5 – 4,5 volt signal output, see pin assignment below.
0.5 volt signal = Zero (ambient air pressure)
4.5 volt signal = 5bar
