正確な温反伝達が行われない問題があった。The above conventional technology does not take into account the temperature change of the thermistor connection cord, and when the temperature of the hydrothermal wall is transmitted to the thermistor element Y, the temperature of the connection cord changes to λ. Heat is radiated from the connection cord with Y,
There was a problem that accurate temperature/reflection transmission was not performed.

することがない。Heat from the heat-sensitive wall is transmitted to the thermistor element, and the temperature of the thermistor element changes, resulting in a resistance change due to temperature-resistance characteristics and is transmitted to the abrasive device via the connection cord. At this time, since the connection cord is connected to the heat-sensitive wall, even if the ambient temperature (air temperature) of the connection cord changes when heat is transferred to the thermistor element, the heat of the thermistor element will not escape through the connection cord. The temperature of the heat-sensitive wall is accurately transmitted to the thermistor element. As a result, the temperature of the heat-sensitive wall is converted into the resistance of the thermistor and transmitted to the control device, thereby preventing malfunction.
以下、本発明の一実施例を第１図により説明する。 An embodiment of the present invention will be described below with reference to FIG.

とができて、誤動作を防止できる。The temperature of the heat-sensitive wall 3 changes due to the temperature change of the liquid 2 of 1 yen of concrete, and the heat is transferred to the reinforcement case 5 and the connection cord 7vc.
Conveyed. The heat is transmitted to the thermistor element 4 via the heated insulating resin 6 transmitted to the protective case 5, and the thermistor element 4 changes its resistance and sends a signal to the control position 1]41fC via the connection cord 7. At this time, even if the temperature around the heat-sensitive wall 3 changes, the connection cord 7 is in contact with the heat-sensitive wall 3 and has the same temperature as the thermistor element 4, so the heat of the thermistor element 4 is transferred to the connection cord 7. There is no running away from it. As a result, the temperature of the heat-sensitive wall 3 can be accurately transmitted to the 1611-device, and malfunctions can be prevented.
