General Purpose Pressure Sensor

Type: PMSA/PMHA

 

Pressure 1…400MPa
Accuracy ±0.5%FS(PMSA), ±0.25%FS(PMHA)
Output 1~1.5mV/V

 

Description

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