This HVAC liquid line indicator is essential for confirming a full head of liquid at the expansion valve and verifying the effectiveness of the system’s filter drier during routine maintenance or after-service recovery

maintaining electrical isolation between the sensitive control logic and the inductive load side

Automatic Reset Logic: The 150-180F auto limit switch functionality ensures the system recovers automatically after a high-limit event once safe temperatures are restored

ensuring accurate thermal feedback for mission-critical refrigeration and HVAC applications
