 II. Working Principle

Using the piezoresistive effect of monocrystalline silicon, using monocrystalline silicon as the matrix, according to the specific crystal orientation, the elastic elements are formed by advanced micro-mechanical processing technology, and four equivalent strain resistors are formed by integrated circuit technology at the appropriate position to form the Whiston bridge, which is applied a constant voltage (current) to the bridge when there is pressure (differential pressure). When the elastic element is reached, the voltage signal proportional to the corresponding pressure is output. The voltage signal is amplified by electronic circuit and converted into 0-5V output of three-wire system.
