Johnson Controls P499VAP-105K Pressure Transducer Kit

The Johnson Controls P499VAP-105K is a precision electronic pressure transducer engineered for demanding HVACR applications, providing a linear 0 to 10 Vdc output signal. Designed for high-side pressure monitoring in commercial refrigeration and air conditioning systems, this kit features a 0 to 500 psi range with a robust 1/8"-27 NPT external thread fitting. As the direct replacement for the legacy P499VAP-105, it utilizes a stainless steel construction to ensure compatibility with most non-corrosive refrigerants, including ammonia and high-pressure media. The Packard electrical connection integrated into the design offers an IP67 rating, protecting internal electronics from moisture and vibration. This specific kit includes a 6.6' wiring harness, simplifying field installation and ensuring system pressure control accuracy. Its low power consumption and high EMI/RFI shielding make it an essential component for contractors maintaining refrigeration pressure monitoring systems requiring long-term stability and precise signal feedback.

Common Questions

Is the wiring harness included with the P499VAP-105K?
Yes, this kit is specifically designated with the "K" suffix, meaning it includes the 6.6-foot (2-meter) Packard wiring harness required for the electrical interface.

Can this transducer be used on the high-pressure side of an R-410A system?
With a 0 to 500 psi range and robust burst pressure ratings, this pressure transducer is suitable for most standard high-side refrigerant applications within that pressure window.

What is the thread size for the mechanical connection?
The unit features a standard 1/8"-27 NPT external thread, providing a secure, leak-proof fit for standard manifold or pipe taps.
