China Smart 4-20mA Pressure Sensor Transmitter With Low Power
China smart 4-20mA pressure sensor transmitter with low power
China smart 4-20mA pressure sensor transmitter with low power, 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.
