- AO3051 monocrystalline silicon differential pressure/pressure transmitter
measuring principle
The product utilizes the piezoresistive effect of monocrystalline silicon for measurement.It employs a fully welded,integrated oil- filled process,with monocrystalline silicon wafers serving as elastic elements inside.Using integrated circuit technology,a set of equivalent resistors is diffused in specific directions on the monocrystalline silicon membrane,forming a bridge circuit.The monocrystalline silicon wafer is placed inside the sensor cavity. When pressure changes occur,the monocrystalline silicon deforms,causing the strain resistor directly above it to change proportionally with the measured pressure.The bridge circuit then generates the corresponding voltage output signal.In recent years, with the continuous development and maturation of monocrystalline silicon sensor technology in China,it has largely replaced the traditional capacitive sensors in this field.
