application

Electric contact bimetallic thermometers are used in production sites for temperature control and alarm. Directly measure the temperature of liquid, steam, and gas media within the range of -80~500 ℃ 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

Electric contact bimetallic thermometer uses temperature changes to drive contact changes. When it contacts or disconnects with the upper and lower limit contacts, the relay in the circuit works to automatically control and alarm.
