Standardized Calibration: Pre-set to 140 degrees Fahrenheit to align with furnace high limit switch safety parameters

it manages fan cycling and compressor protection with minimal bounce

verify your wiring integrity and check for induced transient voltages from nearby high-voltage lines

It should be installed in the discharge air duct at a point where the air and gas have had sufficient distance to mix

making it a reliable choice for both new installs and retrofits in hydronic heating and cooling systems

York 025-28678-102 Pressure Transducer Refrigerant Standardized Calibration: Pre-set to 140The York 025 28678 102 Evaporator Pressure Transducer is a precision engineered HVAC OEM alternative for critical pressure monitoring in commercial chiller systems. As an essential refrigerant pressure sensor, this unit converts evaporator side pressure into a stable 0 5 VDC linear signal, allowing your unit controller to maintain optimal superheat and prevent coil freeze up. Built for the rigors of mechanical rooms, this 025 28678 102 transducer
