Product features:
Application
Electric contact bimetallic thermometer used in the production of the temperature required for automatic control and alarm. It can directly measure the temperature of liquid, steam and gas in the range of -80 in -+500.
Main features
On site display temperature, intuitive and convenient;
With automatic cutting off power and alarm function;
Safe and reliable, long service life;
Various structural forms, can meet the different requirements
Working principle
Electric contact bimetallic thermometer is the use of temperature changes when the contact changes, when the contact with the upper and lower limit contact or disconnect, so that the circuit of the relay action, so as to automatically control and alarm.
