Sapp supply FTS three-speed switch thermostat dual temperature control thermostat to warm the Smart Thermostat

Thermostat working principle: different thermal expansion coefficients, the bimetal when the temperature changes, both sides of the different levels of thermal expansion and contraction, so at different temperatures, the bending degree of change. Temperature above the expansion temperature of the bimetal, the deformation of the bimetal contact locations is disconnected, the circuit is disconnected. Temperature below the expansion temperature of the bimetal, the bimetal contacts return to their original position and the closed circuit is closed. Thermostat of normally open and normally closed NC: When the set temperature, the thermostat is in the normally closed state, when the actual ambient temperature falls below or close to the set temperature, the load will start heating temperature is usually controller in a normally closed state, when the actual ambient temperature is higher than the set temperature, the load is always in stop running. Normally open: When the set temperature, the thermostat is in the normally open state, when the actual ambient temperature is higher than the set temperature will be close, it will start cooling load, usually are in the thermostat normally open state, when the actual ambient temperature below the set temperature, the load is always in a shutdown state. Large scale data set range with DIN rail mounting Easy adjustable high switching capacity incubator NC (normally closed); thermostat opens at temperature rise fitted with a red temperature dial.
