Semiconductor Diaphragm type Pressure Sensor Device / Element
OEM production of semiconductor sensor devices and sensor elements
VALCOM also supplies OEM sensor devices and sensor elements.
Semiconductor silicon chips can be made with thicker diaphragm, compared with metal chips, which improves pressure resistance of pressure sensors. In case of sensor elements, double diaphragm system is adopted that receives pressure via highly corrosive-resistant metal diaphragm made of Hastelloy C22 or SUS316L.
- Sensor elements capable of measuring positive, negative, compound and absolute pressures can be manufactured.
- Pressure port that is directly in contact with the media to be measured can be made of Hasteloy C22 or SUS316L, which offers good corrosion resistance.
- Excellent pressure resistance performance thanks to thick diaphragm of silicon chip for detecting pressure
