Johnson Controls P499RAP-105 Pressure Transducer

The Johnson Controls P499RAP-105 is a high-performance electronic pressure transducer engineered for precision monitoring in commercial refrigeration and HVAC systems. Built with a single-piece machined 17-4PH stainless steel pressure port, this unit eliminates internal O-rings and welds, providing a leak-proof seal compatible with a vast range of refrigerants, including ammonia and CO2. This P499 series model features a 0-500 PSI pressure range and delivers a 0.5-4.5 Vdc ratiometric output signal, making it a reliable choice for integration with Penn pressure controls and other building automation systems. Its 1/8" NPT external thread (Style 49) and Packard electrical connection ensure a secure, direct-mount installation. Designed to withstand harsh environments, the environmental protection of its electronics resists condensation, icing, and vibration, maintaining a 1% total error band for high-accuracy performance. This transducer is an essential component for technicians requiring stable suction or discharge pressure data in demanding HVACR applications.

• All-Metal Construction: The 17-4PH stainless steel port resists damage from pressure pulsations and physical shock while preventing refrigerant loss.
• Wide Media Compatibility: Suitable for use with water, glycol, condensate, and most corrosive or non-corrosive refrigerants.
• Rugged Reliability: Rated for IP67 environments, ensuring consistent operation despite high humidity or freeze-thaw cycles on suction lines.
• Slim Profile: Slender body design facilitates the use of deep-socket wrenches, requiring zero turning radius for tight installations.

Is the wire harness included with this part?
The P499RAP-105 is an individual pack and typically requires a separate Packard wire harness. If you require a complete kit including the harness, look for the 'K' suffix model, such as the P499RAP-105K.

What is a ratiometric output signal?
This transducer uses a 5VDC nominal supply voltage. The 0.5-4.5 Vdc output "ratios" based on that supply; the signal strength is directly proportional to the sensed pressure relative to the input voltage.

Can this be used on the high side of a R-410A system?
Yes, with a 500 PSI maximum range, this transducer is capable of monitoring pressures in various commercial refrigeration and air conditioning circuits, provided the operating pressure stays within the specified range.
