1. Product application scope: Small mechanical thermostats are designed to control electric heaters or cooling fans in electrical cabinets, which are accidental due to temperature factors. 2. Product introduction: 1. Wide temperature range adjustment 2. Small size 3. Simplified installation 4. High switching performance and high sensitivity ZR011: Thermostat (normally open and normally closed integrated design), heating and cooling dual-use 3. Working principle: Due to the different thermal expansion coefficients, when the temperature of the bimetallic sheet changes, the degree of thermal expansion and contraction on both sides is different, so the bending degree changes at different temperatures. When the temperature is higher than the expansion temperature of the bimetallic strip, the contact position of the bimetallic strip is deformed and disconnected, and the circuit is disconnected. When the temperature is lower than the expansion temperature of the bimetallic strip, the contact position of the bimetallic strip is restored to its original shape and closed, and the circuit is closed. The thermostat is divided into two types: normally open and normally closed Normally open: When the temperature is set, the thermostat is in Normally open state. When the actual ambient temperature is higher than the set temperature, it starts the load heat dissipation. Usually, the thermostat is in the normally open state. When the actual ambient temperature When the temperature is lower than the set temperature, the load is always in a stop state Normally closed: When the temperature is set, the thermostat is in the normally closed state. When the actual ambient temperature drops or approaches the set temperature, the load heating starts. Usually, the thermostat is in the normally closed state. When the temperature is higher than the set temperature, the load is always in a stop state.
