Xylem-Mcdonnell & Miller 7B Potentiometer Switch Proportional Signal 110800 UPC Code: 751875000113

The Xylem-McDonnell & Miller 7B Head Mechanism Potentiometer Switch used as a monitoring and controlling for HVAC System liquid levels in both boilers and water level control applications. The operates with a which changes resistance levels to float position to deliver specific feedback to control systems. The device maintains precise water levels through its operation which stops dry firing events and protects system components. This operates reliably because this design approach reduces maintenance requirements while supporting extended service duration. The mechanism operates to preserve boiler functionality at its better level while protecting the system from damage in demanding HVAC applications.
