Johnson Controls P499RCH-401 Pressure Transducer
The Johnson Controls P499RCH-401 is a high-accuracy refrigeration pressure transducer engineered for demanding HVACR environments. Designed to provide a linear 0.5 to 4.5 Vdc output signal, this ratiometric sensor monitors a pressure range of -1 to 8 Bar, making it ideal for low-side suction monitoring or head pressure control in light commercial systems. The unit features a durable stainless steel construction and is compatible with all common non-corrosive refrigerants, ensuring long-term reliability against vibration and pressure spikes. Installation is streamlined via the 1/4" SAE 45 degree flare internal thread (7/16-20 UNF), which includes a built-in Schrader valve depressor for direct mounting without requiring additional piping. Electrical termination is handled by a Hirschmann Form C connection, and the package includes the essential mating cable socket for immediate field integration.
Key Benefits:
- Compatible with HVAC pressure sensors applications requiring high-precision Ratiometric output.
- Robust stainless steel pressure transducer design resists chemical degradation and mechanical wear.
- The 1/4" SAE internal flare with depressor pin simplifies service and minimizes refrigerant loss during setup.
- Wide operating temperature range ensures stable electronic pressure control in varied ambient conditions.
- Compact form factor allows for installation in tight mechanical cabinets and manifold assemblies.
Common Questions:
What is the primary application for the -1 to 8 Bar range?
This specific range is optimized for suction pressure monitoring and evaporator control, providing high-resolution feedback for VFD compressors and electronic expansion valves.
Does this sensor require a specific power supply?
Yes, as a ratiometric Johnson Controls P499 series sensor, it typically operates on a 5 Vdc supply from the controller to ensure the output signal scales accurately with the supply voltage.
Can I use this with ammonia or corrosive fluids?
No, this transducer is designed for use with HLFC and HFC refrigerants. For ammonia applications, a different series with compatible wetted parts must be used.
Disclaimer: While we strive for 100% accuracy, product data and specifications are subject to change. Please contact our team to confirm compatibility or technical details before purchasing.
