OVERVIEW

The PX2 and PX3 Series are fully calibrated and temperature compensated from -40°C to 125°C [-40°F to 257°F].

PX3 SERIES:

• Total Error Band (TEB) ±1.0 %FSS from -20°C to 85°C: Provides the most comprehensive, clear and meaningful indication of the sensor’s true measurement performance over a specified temperature range; small error promotes system uptime and efficiency.
• 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.
• High external freeze/thaw resistance: Survives exposure to frost, commonly found in refrigeration systems.
• Reduced current consumption: Helps to reduce energy costs, and enhances product life if used in battery driven systems.
• Media compatibility: Common HFC (hydrofluorocarbon) refrigerants such as R410A and R134A, next generation low global warming potential (GWP) refrigerants such as R448A (Solstice® N40), R32 and R1234ZE, engine oil, petroleum-based hydraulic fluids, brake fluids, and dry air.

PX3 APPLICATONS:

• Industrial: Refrigerant pressure monitoring in HVAC/R systems; air compressor system pressure
• Transportation: Air system monitoring; hydraulic oil pressure monitoring

PX2 SERIES:

The PX2 Series has a Total Error Band of ±2% over the operating temperature range of -40 ºC to 125 ºC [-40 °F to 257 °F].

The PX2 Series is compatible with a variety of harsh media including brake fluid, common hydrofluorocarbon refrigerants, engine oil, hydraulic fluids, and compressed air. The wide operating temperature range, ingress protection up to IP69K, and 100 V/m radiated immunity allow for reliable performance in tough environments.

These transducers measure absolute, sealed gage, or vented gage pressure. The absolute versions have an internal vacuum reference and an output value proportional to absolute pressure, the sealed gage versions have an internal pressure reference of one atmosphere at sea level, and the vented gage versions measure pressure with respect to ambient pressure.

The PX2 Series is calibrated using three different units of pressure:

• 1 bar to 70 bar
• 100 kPa to 7 MPa
• 15 psi to 1000 psi

PX2 APPLICATONS:

• Industrial: Refrigerant pressure monitoring in HVAC/R systems; air compressor system pressure
• Air Compressors: Compressor inlet and outlet pressure; Compressor oil pressure; Filter pressure drop
