Electric contact bimetallic thermometers are used in production sites for automatic temperature control and alarm. Direct measurement of body and steam within the range of -80 to 500 ℃ in various production processes

And the temperature of the gas medium.

Characteristics of electric contact bimetallic thermometer:

·On site temperature display, intuitive and convenient;

·Equipped with automatic power-off and alarm functions;

·Safe and reliable, with a long service life;

·Multiple structural forms can meet different requirements.

Working principle of electric contact bimetallic thermometer

Electric contact bimetallic thermometer uses temperature changes to drive contact changes. When it is connected to the upper and lower limit contacts or disconnected, the relay in the circuit is activated to automatically control and alarm.
