Honeywell’s PX3 Series Pressure Transducers use piezoresistive sensing technology with ASIC (Application Specific Integrated Circuit) signal conditioning in a brass housing and Metri-Pack 150 electrical connector. The PX3 Series are fully calibrated and temperature compensated from -40 F to 257 F (-40 C to 125 C)


  • Total Error Band (TEB) (±1.0 %FSS typ.): Provides the most comprehensive, clear and meaningful indication of the sensor’s true measurement performance over a specified temperature range.
  • High insulation resistance and dielectric strength: Protect the user and sensor in high over-voltage situations, and ensures that the device is compliant with industry standards
  • High EMC performance: Operates reliably in the presence of electro-magnetic fields, such as near wireless signals, RF communication, and electrical devices
  • Low current consumption: Helps to reduce energy costs, and enhances product life if used in battery driven systems.
  • Media compatibility: Common HFC (hydrofluorocarbon) refrigerants, next generation low global warming potential (GWP) refrigerants such as R32 and R1234ZE, petroleum oils, lubricants, hydraulic fluids, brake fluids, air and water. For ammonia and other corrosive media, see Honeywell’s MLH Series.
  • RoHS, REACH, and CE compliant
