Abstract
The utility model discloses an interconnected control system for three temperature sensors of a water-resisting thermotank. The system comprises a cabinet body, a cabinet door, and an electric cabinet. A glass door is disposed between the cabinet door and the cabinet body. Seal rings are respectively disposed between the glass door and the cabinet body, and between the cabinet door and the cabinet body. The system is reasonable in design, and simple in structure. A CPU processor is disposed in the electric cabinet. Temperature of the thermotank is controlled by three temperature sensors on different positions through the interconnected control system formed by the CPU processor. The three temperature sensors on different positions respectively acquire temperature data, and the CPU processor processes the data. Thus, temperature of a working cavity inside the cabinet body is induced, measured, and controlled, so that temperature is very stable, accurate, and uniform, and temperature safety performance is relatively good.
Description
Technical field:
The utility model relates to a kind of constant temperature oven, is specifically related to a kind of water isolation type constant temperature oven three-temperature sensor interlock control system.
