Flat Base Pressure Sensor

 

OEM Welded Flat Base (19mm*7.5mm)Pressure Sensor uses a high-sensitivity piezoresistive silicon die as sensing component, which is protected against ambient influences by SS316 housing sealed with a concentrically corrugated diaphragm. Inside the housing, the filled silicone oil assures the measured pressure can be transmitted onto silicon die and then transform the pressure to electric signal.

Welding Flat Base Pressure Sensor is available ranges: -100kpa-10KPa-3.5MPa.

Applications：

● Industrial process control

● Level measurement

● Gas, liquid pressure measurement
