Abstract

The invention relates to the technical field of thermotechnical detection equipment, and particularly discloses a thermocouple calibrating device. The device is used for calibrating a thermocouple to be tested and comprises a temperature adjusting module, a measuring module and a bearing module used for bearing the temperature adjusting module and the measuring module. The temperature adjusting module comprises at least two verification furnaces, a temperature control unit for adjusting the temperature of the verification furnaces and a conversion unit capable of enabling the temperature control unit to be in communication connection with any verification furnace, and when the verification furnaces are connected with the temperature control input port, the temperature of the verification furnaces is the same as that of the thermocouple to be tested; the measurement module comprises a low-thermal-potential scanning switch selectively connected with the measurement output port and a voltage measurement unit used for measuring the thermocouple to be measured; the bearing module can move in a horizontal plane and comprises lifting platforms capable of ascending and descending in the vertical direction, the number of the lifting platforms is the same as that of the verification furnaces, and each lifting platform bears one verification furnace. According to the device, the verification efficiency can be improved in a mode of alternately using the verification furnaces, and the working flexibility is improved by means of structural optimization.

Description

technical field [0001] The invention relates to the technical field of thermal detection equipment, in particular to a thermocouple verification device. Background technique [0002] Thermocouples and thermal resistances are commonly used temperature measuring components in temperature measuring instruments, and are one of the "compulsory verification" items stipulated by the Metrology Law of my country. Since there are many types of temperature measuring elements such as thermocouples and thermal resistances, temperature measuring elements of different models and different measurement ranges cannot be verified together, and it takes a long time to verify a batch of thermocouples. At this stage, the verification generally adopts a single-furnace verification, and only one furnace thermocouple can be verified each time, causing other furnaces to be vacant during the verification process. The disadvantage is that the verification efficiency is low and cannot meet the needs of ...
