Anti-condensation pressure sensor 0-5V 4-20Ma Pressure transmitter for Ice machines  freezers

PT-401 pressure transmitter is a special product developed for refrigeration, heating and other industries. Using the piezoresistive sensor core from an internationally renowned company, the pressure of the measured medium is converted into a 4~20mA, 0~5VDC analog signal through a highly reliable amplification circuit and precision digital temperature compensation and non-linear correction technology;
The unique anti-condensation design prevents water vapor in the sensor cavity from condensing and damaging the circuit board. High stability and high cost performance can be widely used in refrigeration industries such as air conditioners, refrigerators, freezers, water-cooled screw units, etc.
