Johnson Controls P499ACP-105 Pressure Transducer

The Johnson Controls P499ACP-105 Pressure Transducer is a heavy-duty solution designed for precise pressure monitoring in commercial refrigeration and HVAC/R systems. Field-tested for reliability, this sensor features a 0-500 PSI pressure range and provides a 1% total error band for highly accurate performance. The 4-20 mA output signal ensures a stable, linear linear transmission of data even in high-interference environments, making it compatible with a wide range of electronic controllers. Built with a single-piece machined 17-4PH stainless steel pressure port, the P499ACP-105 eliminates risks associated with O-ring failures or weld leaks. Its Style 47 connection, incorporating a 1/4" SAE flare internal thread with depressor, allows for direct mounting to standard pressure tap ports with zero turning radius. Whether managing suction lines or high-side discharge, this 0-500 PSI transducer withstands extreme ambient temperatures, humidity, and icing cycles without signal drift.

• Extreme Durability: Machined 17-4PH stainless steel construction resists physical shock, vibration, and pressure pulsations.
• Leak-Proof Design: The all-metal sealed system contains no organic materials or welds exposed to media, preventing refrigerant loss.
• Environmentally Protected: Electronics are sealed to IP67 standards, making them resilient against condensation and freeze/thaw cycles.
• Broad Compatibility: Suitable for use with most non-corrosive refrigerants, water, glycol, and even ammonia.
• Easy Installation: The slender body design facilitates the use of deep-socket wrenches in tight mechanical spaces.

What is the benefit of the Style 47 connection on the P499ACP-105?
The Style 47 connection includes a 1/4" SAE flare internal thread with an integrated depressor, which allows the transducer to be mounted directly onto Schrader valves without needing additional adapters, saving time during field installation.

Is this transducer compatible with ammonia systems?
Yes, the 17-4PH stainless steel pressure port is compatible with ammonia as well as other common non-corrosive and corrosive media used in industrial cooling.

Does this unit come with the wiring harness?
This specific model is the individual transducer. A Packard electrical connector wire harness (such as the WHA-PKD3 series) must be sourced separately if not already present in the system.
