Johnson Controls P499VCP-107 Pressure Transducer

The Johnson Controls P499VCP-107 Pressure Transducer is a heavy-duty solution for high-side pressure monitoring in commercial refrigeration and HVAC systems. Engineered with a 0–750 PSI range, this sensor provides a precise 0–10 VDC output signal, making it ideal for head pressure control, fan speed regulation, and compressor protection in high-pressure applications. The sensor utilizes a single-piece 17-4PH stainless steel pressure port, eliminating the risk of refrigerant leaks common in transducers with internal O-rings or weld joints. This robust construction ensures it stands up to the mechanical stresses of vibration and pressure pulsations typical in demanding industrial environments.

Designed for immediate integration, the P499VCP-107 features a 1/4" SAE 45° internal thread with a built-in Schrader valve depressor for direct-mount installation. The Packard electrical connection ensures a secure, environmentally protected link to your controller. This ratiometric transducer is digitally compensated to provide a 1% total error band, maintaining high accuracy across wide temperature swings and high-humidity suction line conditions. Whether you are managing complex chillers or standalone industrial process controls, this Johnson Controls pressure sensor delivers the repeatable performance required for modern energy-efficient systems.

• Corrosion Resistance: 17-4PH stainless steel construction is compatible with ammonia, CO2, glycol, and most modern refrigerants.
• Leak-Proof Reliability: Solid-metal machined port removes failure points associated with welds and organic seals.
• Precision Control: High-accuracy 0–10 VDC signal enables fine-tuned adjustments for fan speed and compressor management.
• Application Versatility: Rugged design handles extreme environmental factors, including freeze/thaw cycles on suction lines.
• Compact Profile: Slender body design allows for easy installation using deep sockets in tight equipment cabinets.

What is the accuracy of the P499VCP-107?
This transducer provides a 1% full span maximum accuracy over the entire compensated temperature range, ensuring stable readings for sensitive control logic.

Does this unit come with a wire harness?
The P499VCP-107 is the transducer only; the Packard wire harness must be ordered separately to complete the installation.

Can I use this with corrosive media?
Yes, the all-metal 17-4PH stainless steel port is compatible with any media that does not react with that specific alloy, making it suitable for water and ammonia systems.
