China 4-20mA pressure transmitter diaphragm of bottom price

China pressure transmitter diaphragm without liquid transmission, the pressure directly on the front surface of the ceramic diaphragm, so that the diaphragm has a small deformation, thick film resistance printed on the back of the ceramic diaphragm, connected into a Wheatstone bridge (closed bridge), due to the piezoresistive effect of the varistor, the bridge is generated with a high linearity proportional to the pressure, and the voltage signal is proportional to the excitation voltage. The voltage signal is converted to a 4~20 mA current signal through the modulation amplifier circuit.
