Produkt-Neuheit

The PT-409 pressure transmitter is a special product developed by our company for the refrigerant industry. Adopting the piezoresistive sensor core of an internationally renowned company, through a high-reliability amplifying circuit and precise digital temperature compensation and nonlinear correction technology, the pressure of the measured medium is converted into 4~20mA, 0~5VDC analog signal; unique protection Condensation design avoids damage to the circuit board due to condensation of water vapor in the sensor cavity. With high stability and high-cost performance, it can be widely used in refrigeration industries such as air conditioners, refrigerators, freezers, and water-cooled screw units.
