application
Electric contact bimetallic thermometer used in production field of temperature control and alarm automatically. Can be directly measured in the process of various production - 80 ℃ to + 500 ℃ within the scope of liquid, steam and gas medium temperature.
The main features
The scene display temperature, intuitive and convenient;
With functions of automatic cut off power and alarm;
Safe and reliable, long life;
Many kinds of structure forms, can meet different requirements
The working principle of
Electric contact bimetallic thermometer is the use of lead contact changes when temperature changes, when touch point contact with the upper and lower limits or disconnected at the same time, make the circuit of relay action, to control and alarm automatically.
