Johnson Controls P499ACP-107 Pressure Transducer

The Johnson Controls P499ACP-107 Pressure Transducer is a heavy-duty, direct-mount sensor engineered for high-pressure commercial refrigeration and HVAC applications. Built with a single-piece 17-4PH stainless steel pressure port, this transducer eliminates common failure points like O-rings or welds, ensuring a leak-proof seal even in high-vibration environments. The 0-750 PSI range and 4-20 mA output signal provide precise, linear data transmission to your system controller, maintaining a 1% total error band for superior accuracy. Designed with a 1/4" SAE flare internal thread and integrated depressor (Style 47), it allows for seamless installation on standard access valves without refrigerant loss. The environmentally protected electronics are robust enough to handle the freeze-thaw cycles of suction lines and are compatible with all non-corrosive refrigerants and ammonia, making it an essential component for reliable head pressure control and system monitoring.

Key Benefits for Technicians:

• Durable Construction: The solid 17-4PH stainless steel body resists physical shock, pressure pulsations, and corrosive media.
• High Accuracy: Delivers reliable performance with a 1% total error band across a broad compensated temperature range.
• Simplified Installation: The slender body design allows for the use of deep-socket wrenches in tight spaces with zero turning radius.
• Broad Compatibility: Suitable for use with water, glycol, CO2, and most modern refrigerants including ammonia.

Common Questions & Technical Support:

• What electrical connector does the P499ACP-107 use? This model features a standard 3-pin Packard connector; please note that the wire harness is typically sold separately unless purchased as part of a kit.
• Is this transducer compatible with ammonia systems? Yes, the 17-4PH stainless steel construction is specifically designed to handle corrosive media like ammonia.
• Can I use this for suction line monitoring? Absolutely. The electronics are environmentally sealed to withstand the condensation and icing common in suction line applications.
