Johnson Controls P499RAP-105K Pressure Transducer

Experience reliable pressure monitoring in commercial refrigeration and HVAC systems with the Johnson Controls P499RAP-105K. As a robust 0-500 PSI pressure transducer, this unit is engineered for precision sensing in demanding environments. It features environmentally protected electronics and a 17-4PH stainless steel pressure port, ensuring a leak-proof, all-metal seal that resists damage from vibration, physical shock, and pressure pulsations. Designed for direct-mount applications, it provides a 0.5-4.5 Vdc ratiometric output signal, making it compatible with a wide range of electronic controllers and building automation systems.

The P499RAP-105K transducer includes a 6.5' wire harness with a Packard connector for simplified field installation. Its slender body design is optimized for use with deep-socket wrenches, requiring zero turning radius in tight mechanical spaces. This HVAC pressure sensor is digitally compensated to maintain a 1% total error band across a broad temperature range, effectively resisting the effects of humidity, icing, and condensation on suction lines or discharge headers. Whether monitoring high-pressure refrigerants or non-corrosive fluids, this Johnson Controls pressure transmitter delivers consistent, repeatable performance for professional contractors.

• Broad Media Compatibility: The 17-4PH stainless steel construction is compatible with ammonia, CO2, water, glycol, and all common non-corrosive refrigerants.
• Leak-Proof Design: Single-piece machined port eliminates O-rings and welds, preventing refrigerant loss and potential points of failure.
• High Accuracy: 1% total error band ensures precise data for fan speed controls, compressor staging, and system diagnostics.
• Rugged Durability: Verified for use in Class I, Division 2 hazardous locations and built to withstand frequent freeze/thaw cycles.

What is the maximum overpressure rating for this unit?
The P499RAP-105K is rated for a maximum working pressure of 2x the range (1,000 PSI) and a burst pressure of 5x the range (2,500 PSI) for short-duration abnormal conditions.

What supply voltage does this transducer require?
This ratiometric version requires a stable 5.0 VDC (±0.25 VDC) supply, typically provided by the controller's regulated power output.

Can I use this for suction line applications?
Yes, the environmentally protected electronics are specifically designed to handle the condensation and icing common in HVAC/R suction line and freeze/thaw applications.
