Digital display integrated temperature converter controller, also known as temperature switch, temperature controller, is an integrated temperature measurement display, analog output and alarm output as one of the products, can be used with the flash alarm in the field control point to play a warning and alarm function, can also control electrical appliances open and close. Field temperature display control instrument product is the concentrated performance of thermal resistance temperature sensor and intelligent measurement and control instrument products, with high measurement accuracy, compact structure, complete functions, beautiful appearance, complete replacement of electric contact bimetal thermometer, electric contact pressure thermometer, the product has the ordinary type and flameproof type. Suitable for industrial automation control and other occasions for temperature measurement and control. The working power supply of the instrument adopts DC 24V or AC 220V, which is extremely convenient to use and can be applied to heating, water supply, chemical industry, water treatment, new energy and other industries.
