The PSO model, the sensing element, has excellent temperature properties by adoRing a self temperature compensation foil strain gauge. A diaphragm and a pressure port thereof are composed as one body for the prevention of leakage. It is also durable to an instant over pressure. It can control the system without any controller due to the output of a 1 or 2 channel NPN open collector switch.
