Precision Thermal Calibration: 140°F opening and 110°F closing points prevent heat exchanger damage and promote safe operation

Veteran contractors recognize that maintaining the thermal equilibrium of R-22 systems requires this specific balance-port design to handle varying head pressures and evaporator loads effectively

ensuring precise signal continuity without high-resistance interference

the 1/8" NPT vent port should be piped to a safe outdoor location or an approved atmospheric vent in accordance with local mechanical codes

The inclusion of failsafe and signal-loss features ensures that your controls respond predictably in the event of a loop failure

York 025-28678-112 Transducer Els PW 17895 Precision Thermal Calibration: 140°F openingThe York 025 28678 112 Transducer is a precision engineered OEM pressure sensor designed for accurate monitoring in industrial HVAC control systems. Operating on a 5VDC supply, this ratiometric transducer provides a linear output signal ranging from 0. 5 to 4. 5 VDC, calibrated for a stable pressure range of 6 to 74 PSI. As a critical component for York and Johnson Controls chiller assemblies, it facilitates real time pressure feedback to the
