overview：

PT20SR-3483 Piezoresistive Pressure Transmitter adopts OEM piezoresistive sensor as signal measuring element, which is through automatic test and laser trimming to compensate zero and sensitivity in wider temperature range. Sensor signal is transformed into standard output signal by the amplifier circuit. Through long-term aging and stability test, the whole product's performance is stable and reliable. The product is suitable for harsh environment where needs zero shift and range adjustment. It is widely used for process control and pressure measurement of Petroleum, Chemi-industry, Metallurgy, Power station, Textile industry, Building material, Food, Medicine, Hydrology and Environment control, etc.
