Optimized Control: The 4-8 PSI spring range allows for precise sequencing in complex pneumatic control systems

Technicians should verify manifold pressure and coil resistance during diagnostics

It is the primary direct replacement for the HH71PD024 and replaces mercury sensors utilizing Bulb Style #17 or #18

It is typically used in conjunction with an A1044 amplifier and must match the temperature range of the installed sensor

This unit is designed for the standard D-Pilot

York 025-43553-000 Flow Sensor R-410A Optimized Control: The 4-8 PSIThe York 025 43553 000 Flow Sensor is a critical thermal dispersion flow switch utilized across a range of York chillers, including YLAA, YVAA, YVFA, YCAV, and YCIV series. Engineered for high precision monitoring of fluid movement, this sensor functions as an OEM replacement for 025 38145 001 and the SC0517 model. It utilizes a calorimetric operating principle, detecting thermal energy displacement via dual thermistors to ensure accurate refrigerant
