In the process of industrial production, the TC series thermocouple temperature probe is one of the important parameters of measurement and control. In temperature measurement, the application of thermocouple is extremely wide. It has many advantages such as simple structure, convenient manufacturing, wide range of measurement, small inertia, and output signals for easy remote transmission. In addition, because the thermocouple is a passive sensor, it does not need to be added to the power supply during measurement, which is very convenient to use. The TC series thermocouple temperature sensor probe has metal sheaths, mineral insulation (MI) thermocouple materials, and responds rapidly, because protective metal outer condoms allow a smaller diameter thermocouple conductor. The hard compacting magnesium oxide insulation layer further enhances the ability of the sensor to "read" the temperature by quickly transmitting heat to the measurement knot.
