The PT-401 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.

PT-401 Pressure Transmitter Features

  • High-performance diffused silicon sensor core with high-integration bridge pressure sensor signal conditioning dedicated advanced chip.
  • Digital temperature compensation and nonlinear correction.
  • Anti-condensation design to avoid condensation affecting the product.
  • Small size, easy installation, multiple signal output, standard Parker plug, wide adaptability.
  • High sensitivity, high precision, high stability.
  • Full temperature compensation, good electrical performance, long-term stability.
