Johnson Controls P499ACP-107 Pressure Transducer 321702-401 If a trap is blowing

If a trap is blowing live steam or failing to discharge condensate

providing the necessary feedback to the U-Control module to manage firing rates or trigger a safety shutdown if heat exchanger fouling or incorrect combustion occurs

Ensures peak efficiency by preventing heated air from escaping through the flue during burner standby cycles

Regular inspection of the porcelain body is recommended

This piston damper actuator features a substantial 3-inch stroke and is factory-calibrated with a 5 to 10 psi spring range

Johnson Controls P499ACP-107 Pressure Transducer 321702-401 If a trap is blowingThe 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
