Honeywell PX3 Series


Honeywell is pleased to announce the 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. Key features and benefits include:

  • Delivers high efficiency: Proven, ±1.0 %FSS tight Total Error Band accuracy promotes system efficiency and lower energy costs.
  • Great customer value: Economical choice for design/implementation; extremely flexible with multiple configuration possibilities with the right combination of features and broad media compatibility.
  • Durability promotes system uptime: For enhanced performance in tough environments to support overall system quality, reliability and warranty.
  • Fast availability: Short lead times on samples and production parts.

Honeywell Provides Value to Every Customer 

  • 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.

Different than the Competition 

  • Efficient: Proven, tight Total Error Band accuracy.
  • Great customer value: Multiple configuration possibilities with the right combination of features.
  • Durable: Hits the tough environmental specifications customers need, which is higher than many competitive heavy duty pressure transducers’ specifications.
