  • Patent number: 11959814
    Abstract: A high temperature dry block temperature calibrator relates to the technical field of temperature calibration. The high temperature dry block temperature calibrator includes a high temperature furnace, a control board module, a system board module, a measuring board module, a lower support, and a housing. The high temperature furnace and the control board module are mounted on the lower support. The system board module and the measuring board module are mounted on the front side surface of the housing. The housing is clipped to the periphery of the lower support and the high temperature furnace and the control board module are accommodated in the housing. The modules are independent of each other and can be removed separately, thereby facilitating maintenance and replacement. The high temperature dry block temperature calibrator can be used for calibrating the temperature of a high temperature element to be measured.

  • Patent number: 11740139
    Abstract: A flow guiding and heat dissipating type dry block temperature calibrator, which belongs to the temperature calibration field. The temperature calibrator includes a furnace body located in a housing and at least one air flow generating device. The air flow generating device is on one side or at the periphery of the furnace body, and is one or a combination of a gas passage, a flow guiding fan, an air pump and a blower. The air flow generated by the air flow generating device is blown toward a handle of a device being tested that is inserted in the furnace body, such that the handle is cooled, thereby preventing the sensor inside the handle from failing due to high temperature, facilitating the heat dissipation of the internal electronic components of the instrument itself, and extending the service life of the temperature calibrator.

  • Patent number: 11733108
    Abstract: A method for calibrating a short temperature measuring device using a dry body temperature calibrator; wherein a heat soaking block is placed in the furnace of the dry body temperature calibrator, and two temperature measuring holes are in the heat soaking block, the bottom of the furnace includes a temperature control element. This method includes electrically connecting the first standard temperature sensor to the temperature control element through the measuring module and the control module sequentially to form a closed-loop for temperature feedback control, accurately controlling the temperature of the temperature measuring hole, and calculating the temperature difference between the temperature sensor to be calibrated and the standard temperature sensor in the two temperature measuring holes respectively.
