Johnson Controls P499VCP-105 Pressure Transducer

The Johnson Controls P499VCP-105 Pressure Transducer is a heavy-duty, direct-mount solution designed for demanding commercial refrigeration and HVACR systems. Built with a single-piece machined 17-4PH stainless steel pressure port, this sensor eliminates potential leak points by removing internal O-rings and welds. Supporting a 0 to 500 psi range and providing a precise 0 to 10 Vdc output signal, it is ideal for high-pressure side monitoring and condenser fan speed control. The 1/4" SAE 45-degree internal thread (7/16-20 UNF) includes an integral depressor for easy installation on standard access valves. Designed for professional HVAC pressure sensor replacement, it features Packard electrical connection compatibility and is digitally compensated to maintain accuracy across wide ambient temperature swings. Whether you are dealing with ammonia or common non-corrosive refrigerants, this 0-10V pressure transmitter delivers a 1% total error band, ensuring reliable performance in high-humidity and freeze-thaw environments typical of industrial refrigeration controls.

• Rugged Reliability: All-metal 17-4PH stainless steel construction prevents refrigerant loss and resists physical shock and vibration.
• Broad Compatibility: Suitable for use with ammonia, CO2, glycol, water, and most synthetic refrigerants.
• Precision Control: 1% total error band provides high-accuracy data for sensitive HVACR system diagnostics.
• Quick Installation: The slender body design allows for the use of deep-socket wrenches in tight spaces with zero turning radius required.

What is the difference between the P499VCP-105C and the P499VCP-105K?
The "C" suffix denotes an individual transducer, while the "K" version is a kit that includes a 6.5-foot (2m) Packard wire harness and technical literature.

Can this transducer be used on the suction line?
Yes, its environmentally protected electronics are specifically designed to handle the condensation, icing, and freeze-thaw cycles found in suction line applications.

What input voltage is required for the 0-10Vdc signal?
This unit typically requires a supply voltage of 12 to 30 VDC (Class 2 or SELV) to produce the linear 0-10V analog output.
