Description of Electric contact digital bimetal thermometer:

Electric contact bimetallic thermometers WSSX series used in production field of temperature control and alarm automatically.Direct measurement of various production process - 80 ~ 500 °C range, steam and gas medium temperature.

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.
working principle
WSSX lectric contact bimetallic thermometers  is the use of lead contact changes when temperature changes,When contact with the upper and lower limits or disconnected at the same time,The circuit of relay action,To control and alarm automatically.
