Honeywell: New Heavy Duty Pressure Transducers PX3 Series from Honeywell

Honeywell has recently announced its efficient, affordable and durable PX3 Series Heavy Duty Pressure Transducers, designed primarily for system pressure monitoring in HVAC, refrigeration, air compressor, pump and valve systems.

Value to customers

  • Total Error Band: Provides the most comprehensive, clear and meaningful measurement of the sensor’s true accuracy; small error promotes system uptime and efficiency.
  • Enhanced freeze/thaw resistance: Allows the device to survive exposure to frost, commonly found in refrigeration systems.
  • Enhanced insulation resistance and dielectric strength: Protects the user and sensor in high over-voltage situations, and ensures that the device is compliant with industry standards.
  • Enhanced EMC (radiated immunity) performance (200 V/m): Allows for use in the presence of electro-magnetic fields, such as near wireless signals, RF communication and electrical devices.
  • Low current consumption (3.5 mA max.): Helps reduce energy costs and enhances product life if used in battery driven systems.


  • Pressure range: 1 bar to 46 bar | 15 psi to 667 psi (absolute and sealed gage)
  • Ratiometric output: 0.5 Vdc to 4.5 Vdc
  • Fully calibrated and temperature compensated
  • Total Error Band: ±1.0% FSS from -20°C to 85°C [-4°F to 185°F]
