YW-140 piezoresistive pressure transmitter adopts the piezoresistive OEM pressure sensor with stainless steel isolation film as the signal measuring element. After automatic testing by computer, the zero point and temperature performance compensation in a wide temperature range are carried out by laser resistance adjusting process. The signal processing circuit is located in the stainless steel shell and converts the sensor signal into the standard output signal. The whole product has passed the strict test
and aging screening of components, semi-finished products and finished products, and its performance is stable and reliable. With its excellent reliability, flexibility and diversity, the product is widely used in the field pressure measurement and control of petroleum, chemical industry, metallurgy, electric power, hydrology and other industrial processes.
