Johnson Controls P499VCP-101C Pressure Transducer

The Johnson Controls P499VCP-101C is a contractor-grade electronic pressure transducer engineered for high-precision monitoring in commercial HVAC and refrigeration systems. Built with a 17-4PH stainless steel single-piece machined pressure port, this sensor eliminates potential leak points by removing internal O-rings and welds, making it ideal for high-pressure applications and compatible with all non-corrosive refrigerants, including ammonia and CO2. The unit delivers a linear 0 to 10 Vdc output signal over its 0 to 100 psi range, providing reliable data for head pressure control, fan speed modulation, and compressor staging.

Designed for durability in harsh environments, the P499VCP-101C features environmentally protected, digitally compensated electronics that resist the effects of condensation, icing, and vibration. Its slender body design allows for effortless installation with deep-socket wrenches in tight mechanical spaces. The 1/4" SAE 45-degree internal thread includes a built-in depressor (Style 47) for direct mounting, while the Packard electrical connection ensures a secure, weather-tight interface with the system controller. This HVAC pressure sensor is a robust solution for maintaining system efficiency and protecting critical equipment from pressure fluctuations.

• Leak-Proof Reliability: All-metal 17-4PH stainless steel construction prevents refrigerant loss common with inferior weld-joint sensors.
• High-Accuracy Performance: Features a 1% total error band with digital compensation for consistent readings across wide ambient temperature swings.
• Versatile Application: Validated for use in agriculture, chillers, and industrial process control where 0-100 psi pressure monitoring is required.
• Simplified Wiring: Uses the industry-standard Packard connector for quick integration into existing Johnson Controls or third-party wire harnesses.
• Suction Line Ready: Electronics are sealed against moisture, specifically designed to withstand freeze/thaw cycles common on suction lines.

• What refrigerants are compatible with this sensor? It is compatible with all common non-corrosive refrigerants, ammonia, and water-glycol solutions.
• Does this model include the wire harness? This is an individual pack (transducer only); the Packard connector wire harness must be ordered separately.
• Can I use this for head pressure control? Yes, the 0 to 10 Vdc signal is specifically designed for integration with variable frequency drives (VFDs) and fan speed controllers.
