Electrical contacts bimetal thermometer temperature should be applied to the production site for automatic control and alarm. Electrical contacts bimetal thermometer direct measurement of the production process -80 ~ 500 ℃ range of liquid, steam and gas medium temperature. Features safe, reliable, long life; has an automatic cut off power and alarm functions; scene shows the temperature, easy and intuitive; variety of structural forms, which can meet different requirements. Works electrical contacts bimetal thermometer is driven by temperature changes contacts changes, when in contact with the upper and lower contacts or disconnected while the relay circuit to automatically control and alarm.
