Johnson Controls P499RCP-101K Pressure Transducer Kit

Upgrade your system’s reliability with the Johnson Controls P499RCP-101K Pressure Transducer Kit, a heavy-duty sensing solution engineered for high-accuracy performance in demanding commercial refrigeration and HVAC applications. This kit serves as the direct replacement for P399AAC-1-200, featuring a 0.5 to 4.5 Vdc ratiometric output that provides linear pressure data with a 1% total error band. Designed with a single-piece machined 17-4PH stainless steel pressure port, it eliminates common failure points like O-rings and welds, ensuring a leak-proof all-metal seal even under severe pressure pulsations or vibration.

The P499RCP-101K is built to withstand harsh environments, rated at IP67 for superior protection against moisture, icing, and condensation on suction lines. With a 0 to 100 Psi range and field-proven Packard electrical connection, this commercial refrigeration pressure transducer integrates seamlessly into existing control boards. The slender body design allows for zero turning radius, enabling technicians to use deep-socket wrenches for fast installation in tight spaces. This HVAC pressure sensor kit includes a 6.6-foot (2m) wiring harness to ensure a complete, out-of-the-box solution for P399 series transducer upgrades.

Key Benefits:

• Enhanced Compatibility: Functions as a high-performance replacement for P399AAC-1-200 with full ratiometric signal parity.
• Rugged Construction: Machined 17-4PH stainless steel protects against corrosive refrigerants, ammonia, and high-pressure bursts.
• Environmental Resilience: Environmentally-protected electronics prevent signal drift caused by freeze-thaw cycles and high humidity.
• Precise Monitoring: Delivers high-accuracy 0.5 to 4.5 Vdc analog output for tight system diagnostics and head pressure control.
• Ready-to-Install: Kit contains the pressure transducer with 6.6 ft wiring harness to reduce downtime and eliminate extra sourcing.

Common Questions:

Is the P499RCP-101K compatible with ammonia systems?
Yes, the 17-4PH stainless steel wetted parts are compatible with ammonia, CO2, glycol, and most common non-corrosive refrigerants.

Can I use my existing P399 wiring harness with this unit?
While this kit includes a 6.6' wiring harness, the Packard connectors are typically interchangeable with the previous P399 series for convenience.

What is the proper mounting position for this transducer?
For maximum longevity, mount the sensor on the top side of refrigerant lines to prevent oil, sediment, or liquid accumulation from affecting the pressure chamber.
