Pressure Sensor Special for refrigeration and anti-condensation Two-Wire Piezoresistive Pressure transmitter Transducer
Two-Wire Piezoresistive Pressure transmitter PT-409 is a special product developed for refrigerant, refrigeration and heating industries. Using the piezoresistive sensor core of a famous German company, through high-reliability amplification circuit and precision digital temperature compensation and non-linear correction technology, the pressure of the measured medium is converted into a 4~20mA, 0~5VDC analog signal; stainless steel isolation type Small structure, compact appearance and easy installation. 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, ground source heat pumps, etc.
Two-Wire Piezoresistive Pressure transmitter Main Feature:
1. The high-performance diffused silicon sensor core is equipped with a highly integrated bridge pressure sensor dedicated advanced chip for signal conditioning.
2. Digital temperature compensation and nonlinear correction
3. Anti-condensation design prevents condensation from affecting the product and has pressure protection function
4. Compact appearance, easy installation, multiple signal outputs, standard Hirschmann GDM-3009 plug, wide adaptability
5. High sensitivity, high precision and high stability
6. Full temperature zone temperature compensation, good electrical performance and long-term stability
