Johnson Controls P499VCP-107K Pressure Transducer Kit

The Johnson Controls P499VCP-107K is a professional-grade electronic pressure transducer designed for precise monitoring in high-pressure HVACR and industrial refrigeration systems. This kit includes a 0 to 750 PSI transducer featuring a 0 to 10 VDC output signal and a 2-meter (6.6 ft) Packard wiring harness. Built with a 17-4PH stainless steel pressure port, the P499 series utilizes a one-piece machined construction that eliminates internal O-rings and welds, mitigates leak risks, and ensures compatibility with various refrigerants, ammonia, CO2, and glycol. The 1/4" SAE 45-degree internal thread allows for direct mounting on standard service valves. Engineered to maintain a 1% total error band, this transducer withstands extreme environment conditions, including heavy vibration, pressure pulsations, and ambient temperatures from -40°F to 185°F. For technicians integrating this into a control loop, the 12–30 VDC supply voltage ensures seamless interface with most HVAC controllers and building automation systems.

Key Benefits

• High Accuracy: Maintains a 1% total error band for reliable pressure monitoring in critical applications.
• Durable Construction: One-piece stainless steel design resists corrosion and prevents media leakage.
• Environmental Protection: Electronics are sealed to survive freeze/thaw cycles, high humidity, and icing.
• Versatile Compatibility: Suitable for multi-refrigerant systems, water, and industrial pneumatic lines.
• Simplified Installation: Compact body and included pre-wired Packard electrical connection enable quick setup in tight mechanical spaces.

Common Questions

What is the difference between the P499VCP and other P499 models?
The VCP designation identifies a 0 to 10 VDC output signal. Unlike current-based (4-20 mA) or ratiometric models, this unit requires a stable supply voltage and provides a linear voltage output proportional to the 0-750 PSI range.

Can this transducer be used on the high-side or low-side of a system?
With a 750 PSI upper limit, this pressure transducer is primarily utilized for high-side monitoring, head pressure control, or discharge pressure sensing in R-410A, R-404A, and R-134a systems.

Is the wiring harness included in the K-suffix kit?
Yes, the "K" at the end of P499VCP-107K signifies a complete kit that includes the 2-meter wire harness as standard equipment.
