Electrical contact bimetal thermometer

Application:
Electrical contact bimetal thermometerApplied to the production site for automatic temperature control and alarm. Directly measure the temperature of body, steam, and gas media within the range of -80 to 500 ℃ in various production processes.

characteristic
·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
Electrical contact bimetal thermometerIt is to use temperature changes to drive contact changes, and when it is disconnected from the upper and lower limit contacts, the relay in the circuit is activated, thereby automatically controlling and alarming.
