Differential Pressure Sensor (piezoresistive type)

 

Model: HPC20

 

Pressure range: 0-10Kpa~2MPa

 

The HPC series piezoresistive pressure sensor is an OEM sensor with constant current silicon-oil filled pressure sensor. The measured pressure or differential pressure of medium is delivered to a silicon bridge by stainless steel membrane and silicon oil.  Apply the piezoresistance effect of diffused silicon to fulfill the linear transfer from measured pressure to voltage signal. The sensors have characteristics of high reliability, repeatability and stability.

And its stainless steel isolated diaphragm enable it used wide in rugged application widely, such as chemi-industry, process control, liquid pressure system and switch, etc.
