Johnson Controls P499VCP-105K Pressure Transducer

The Johnson Controls P499VCP-105K is a professional-grade electronic pressure transducer kit engineered for high-accuracy performance in commercial refrigeration and HVAC systems. Built with a single-piece 17-4PH stainless steel pressure port, this unit is designed to eliminate common failure points like O-rings and welds, providing a robust, leak-proof solution for demanding environments. This 0 to 500 PSI pressure transducer produces a linear 0 to 10 Vdc output signal, making it a critical component for monitoring high-side head pressure or suction lines in condenser fan speed control applications.

Installation is streamlined with the included 6.6-foot wiring harness and a standard Packard electrical connection. The compact, slender body design requires zero turning radius, allowing technicians to use deep-socket wrenches in tight cabinet spaces. Digitally compensated to resist the effects of wide ambient temperature swings, condensation, and icing, the P499VCP-105K ensures 1% total error band accuracy across its entire operating range. It is fully compatible with most non-corrosive refrigerants, ammonia, water, and glycol, offering versatile HVAC pressure sensor reliability for chillers, pumps, and compressors.

• Durable Construction: The 17-4PH stainless steel diaphragm and port resist physical shock, vibration, and pressure pulsations.
• Environmental Protection: IP67-rated electronics withstand moisture and freeze-thaw cycles on suction lines.
• System Compatibility: The 1/4" SAE 45-degree internal thread with Schrader valve depressor fits standard refrigeration pressure taps without additional adapters.
• Precise Signal: ASIC-conditioned 0-10Vdc output provides stable data for high-level controllers and building automation systems.

Is the wiring harness included with this part?
Yes, the "K" suffix in the P499VCP-105K model number indicates a complete kit, which includes the transducer and a 2-meter (6.6 ft) pre-terminated Packard wire harness.

Can this transducer be used with ammonia systems?
The 17-4PH stainless steel wetted parts are fully compatible with ammonia and other corrosive or non-corrosive media that do not react with this specific steel grade.

How do I verify the transducer is functioning correctly?
With the system stabilized, measure the DC voltage across the output leads; the signal should scale linearly from 0V at 0 PSI to 10V at 500 PSI when compared against a calibrated mechanical gauge.
