The Advantage of Automatic Reset Thermostat

Advantage

- The contacts have good repeatability and reliable snap action;

- The contacts are on and off without arcing, and the service life is long;

- Little interference to radio and audio-visual appliances.

- Lightweight but high durability;

- The temperature characteristic is fixed, no adjustment is needed, and -the fixed value is optional;

- High precision of action temperature and accurate temperature control;

Product Advantage

-Excellent temperature response speed

The thermal conductor is made of high-quality materials to ensure that the environmental heat energy is quickly transferred to the inside of the thermostat, which plays a role in overheating and overload protection.

-Reliable & precise operation

The high-sensitivity temperature sensor ensures that the operating temperature of each thermostat reduces errors, making it more accurate and reliable.

-Long service life

Thermostat can last longer in high temperature environments and have a longer service life.

Feature Advantage

Automatic reset temperature control switch: as the temperature increases or decreases, the internal contacts are automatically opened and closed.

Manual reset temperature control switch: When the temperature rises, the contact will automatically open; when the temperature of the controller cools down, the contact must be reset and closed again by manually pressing the button.

Craft Advantage

One-time action:

Automatic and manual integration.

How does a bimetallic thermostat work

A key component of a bimetal thermostat is the bimetal thermal switch. This part responds quickly to any variations in a preset temperature. A coiled bimetal thermostat will expand during temperature changes, causing a break in electrical contact of the appliance. This is a major safety feature for things like furnaces, where excessive heat can be a fire hazard. In refrigerators, the thermostat protects the appliance from the formation of condensation should the temperature drop too low.
