Honeywell PX2 Series Heavy Duty Pressure Transducers - 1 bar to 70 bar | 100 kPa to 7 MPa | 15 psi to 1000 psi:

Honeywell’s PX2 Series Heavy Duty Pressure Transducers are a portfolio of configurable pressure sensors that use piezoresistive sensing technology with ASIC (Application Specific Integrated Circuit) signal conditioning in a stainless steel housing. The PX2 Series is fully calibrated and compensated for offset, sensitivity, temperature effects and non-linearity using the on-board ASIC. 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, sealed gage versions have an internal pressure reference of one atmosphere at sea level, and vented gage versions measure pressure with respect to ambient pressure. They are RoHS compliant and are designed and manufactured according to ISO 9001 standards.

The PX2 and PX3 Series are designed to provide continuous monitoring of compressor outlet pressure, chiller outlet pressure, evaporator coil outlet pressure, and cooling tower supply pressure to help control the flow of heating/ cooling media during partial load conditions. (See Figure 1.) The PX2 and PX3 Series are compatible with common hydrofluorocarbon (HFC) refrigerants such as R410, R134a, R407a. In addition, the PX3 Series is compatible with next generation low global warming potential (GWP) refrigerants such as R32, R1234ZE, and R448A (Solstice® N40). For Honeywell heavy duty pressure transducers designed for use with ammonia refrigerants, please see the MLH Series, SPT Series, 19 mm and 13 mm Series.
