Digital integrated temperature transmission controller, also known as temperature switch or temperature controller, is a product that integrates temperature measurement display, analog quantity transmission output, and alarm output. It can be used in conjunction with flash alarms to provide warning and alarm functions at on-site control points, as well as to control the opening and closing of electrical appliances. The on-site temperature display control instrument product is a concentrated representation of thermal resistance temperature sensors and intelligent measurement and control instruments. It has the characteristics of high measurement accuracy, compact structure, complete functions, and beautiful appearance, completely replacing electrical contact bimetallic thermometers and electrical contact pressure thermometers. The products are available in both ordinary and explosion-proof types. Suitable for temperature measurement and control in industrial automation control and other applications. The working power supply of the instrument adopts DC 24V or AC 220V, which is extremely convenient to use and can be applied to industries such as heating, water supply, chemical industry, water treatment, and new energy.
