Description of Ceramic Absolute Pressure Sensor Pressure Transmitter 0-5V4-20mA
This pressure sensor 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.
Application of Ceramic Absolute Pressure Sensor Pressure Transmitter 0-5V4-20mA
Process control, environmental control, hydraulic and pneumatic equipment, servo valves and drives, chemicals and chemical industry and medical instrumentation and many other fields.
