Problems solved by technology
If the thermocouple directly measures the temperature of the workpiece, high voltage will be introduced into the temperature control instrument, thus burning the instrument
And the surface of the product is in a plasma state, the complex interference of the electric field and magnetic field will also affect the potential difference of the thermocouple, and the DC pulse power supply itself sends out a 1KHz high-frequency signal, which will also generate an induced potential and affect the output signal of the thermocouple. So that the measured temperature is different from the actual temperature

Abstract
A direct temperature measuring device comprises a temperature measuring assembly and a digital display instrument. The temperature measuring assembly comprises a shell and at least one flexible thermocouple installed inside the shell. A heat insulation material coating the flexible thermocouples is arranged inside the shell. Each flexible thermocouple has a measuring end and a connecting end. Inside the shell, at least one insulating layer is arranged in parallel at one side of the measuring ends of the flexible thermocouples. Outside the shell, a vacuum sealing layer extends from the end face of the shell at one side of the connecting ends of the flexible thermocouples. The connecting ends of the flexible thermocouples are connected with the digital display instrument. The measuring end of each flexible thermocouple is a plane, and the width of the widest part is 0.5-2mm. The direct temperature measuring device further comprises a signal isolation gate which is arranged between the connecting ends of the flexible thermocouples and the digital display instrument. The direct temperature measuring device can be installed on a variety of thermal treatment equipment such as a plasma thermal treatment furnace. With the direct temperature measuring device adopted, the temperatures at multiple points in a thermal reaction device can be measured directly.
Description
Technical field [0001] The invention relates to a temperature measurement device, a plasma heat treatment furnace applying the device and a temperature measurement method using the device for temperature measurement. Background technique [0002] The temperature measuring device is a commonly used device in the field of thermal reaction and heat treatment. In order to monitor the thermal reaction or heat treatment temperature, control the thermal reaction or heat treatment effect, it is necessary to monitor the temperature of the thermal reaction device, the temperature inside the heat treatment device, or the temperature of the workpiece to be processed inside the heat treatment. Due to the high temperature environment inside the thermal reaction or heat treatment device, ordinary temperature measuring devices are not suitable, and special temperature measuring devices are required. One of the main problems of the existing temperature measuring device is that the direct temperat...
