Sterling-Sterlco T562-03-0000 Standard Bulb R/A 3/4" 100°F-175°F 56-T

The Sterling-Sterlco T562-03-0000 Standard Bulb R/A 56-T is a temperature sensing part used for regulating thermal control circuits in heating and cooling equipment. It is applied in heating units where the 3/4" right-angle bulb monitors air or surface temperature within a 100F175F range for accurate response in HVAC systems. It operates through thermal expansion within a sealed sensing element, converting temperature changes into mechanical pressure signals that guide control valves or regulators. The bulb is mounted in the sensing zone and connected to the control assembly, ensuring stable temperature regulation, consistent cycling, and improved operational accuracy in heating applications.
