ZRN201B ceramic pressure transmitter
 

Product description:

ZRN201B ceramic pressure transmitter with ceramic thick film pressure sensor imported special ceramic material, together with intelligent circuit for the full range of linear and temperature compensated pressure can be used to measure small, powerful anti-overload. The products are widely used in petrochemical, power, chemical industry, light industry and other industries need to make minor pressure precision measurement applications.
Main features
1, rugged and sensitive diaphragm ceramic substrate, corrosion resistance, impact resistance, overload is not less than 500%.
2, high sensitivity, wide range.
3, since no dielectric liquid, lowest temperature, high long-term stability.

Third, the ceramic pressure transmitter measurement principle
Corrosion-resistant ceramic pressure sensor did not transfer liquid, the pressure directly on the front surface of the ceramic diaphragm, the diaphragm will produce small deformation, thick film resistors printed on the back of the ceramic diaphragm, connected into a Wheatstone bridge (Closed Bridge), due to the piezoresistive effect varistor, the electrical bridge produces a highly linear proportional to the pressure, and the excitation voltage is proportional to the voltage signal, the standard signal according to the different calibration pressure range of 2.0 / 3.0 / 3.3 mV / V and so on, can strain sensor is compatible laser calibration, the sensor has high temperature stability and time stability, the sensor comes with temperature compensation 0 ~ 70 ℃, and can be in direct contact with the vast majority of media.
