High Durability for Over Pressure, Available with an Output of mV : PMSA/PMHA

Sensor System | Pressure Transducers / Transmitters | View PDF

The PMSA/PMHA model, the sensing element, has excellent temperature properties by adopting a self temperature compensation gauge. A diaphragm and a pressure port thereof are configured as one body for the prevention of leakage. It has superior durability for an instant over pressure.
