A differential thermostat is a vital component in various systems that require precise temperature control based on the difference in temperatures between two points. Unlike traditional thermostats that control temperature at a single point, the differential thermostat adjusts based on the temperature difference between two sensors. This type of thermostat is particularly useful in systems where temperature regulation needs to be more nuanced, such as in HVAC systems, industrial machinery, and laboratory equipment.

    Principle of Operation

    The fundamental working principle of a differential thermostat revolves around comparing the temperatures of two distinct areas or objects. These two locations are typically monitored by two temperature sensors. The thermostat is designed to activate or deactivate a heating or cooling system depending on the temperature difference between these two points.
