Ceramic Piezoresistive Pressure Sensor

The ceramic piezoresistive pressure sensor capsules are made with a ceramic base plate and a flush diaphragm and work following the piezoresistive principle.

Ceramic piezoresistive pressure sensor.

Piezoresistive monolithic ceramic pressure sensor cpa602 series pressure sensors general description the cpa 602 series offers piezoresistive monolithic media isolated ceramic pressure sensors. The jc ct02 compensated isdesigned for o ring mounting and oem applications where compatibility with corrosive media is required. Ceramic piezoresistive sensing technology is also similar in theory to bonded foil strain gage technology. The wheatstone bridge is screen printed on one side of the flush ceramic diaphragm which is in turn glued to the sensor s body.

Sendo sensor is a china based privately held piezoresistive pressure sensor flush pressure sensor low cost pressure sensor and submersible pressure sensor manufacturer was founded in year 2006. It generates a signal as a function of the pressure imposed. This sensing method uses conductive ink deposition on the reference side of a ceramic diaphragm. The conductive ink forms the variable resistance strain gages in a wheatstone bridge circuit.

The wheatstone bridge is screen printed on one side of the flush ceramic diaphragm which is in turn glued to the sensor s body. A given force results in a corresponding charge across the sensing element. Piezoresistive ceramic pressure sensors ps100 series piezoresistive ceramic pressure sensors are based on ceramic. Ess501i ceramic thick film pressure sensor module based on metallux me501 505 ess501i pressure sensor module is made with a ceramic base cell and a flush diaphragm and work following the piezoresistive principle.

The rear part of the diaphragm can be exposed directly to the medium to be measured. A pressure sensor usually acts as a transducer. With more than 10 years fightting in pressure sensor transducer and transmitter sendo accumulated lots of experience in designing and producing as one of the best supplier from china we always. A pressure sensor is a device for pressure measurement of gases or liquids pressure is an expression of the force required to stop a fluid from expanding and is usually stated in terms of force per unit area.

In this paper the effects of mounting on the sensor die are described and two different of pressure sensors in ceramic packages are presented. A charge amplifier converts this to an output voltage proportional to the pressure. Piezoelectric sensors use materials such as quartz crystals or specially formulated ceramics which generate a charge across the faces when pressure is applied. Jc ct02 piezoresistive pressure sensor is a 19 mm small profile media compatible piezoresistive pressure sensor packaged in a 316l stainless steel housing.

Product highlights include excellent chemical resistance and mechanical robustness.
