Patent number: 11959814Abstract: 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.Type: GrantFiled: January 7, 2019Date of Patent: April 16, 2024Assignee: BEIJING CONST INSTRUMENTS TECHNOLOGY INC.Inventors: Jianjun Lin, Xuecan Li, Chengjiang Wu

Patent number: 11740139Abstract: 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.Type: GrantFiled: January 8, 2019Date of Patent: August 29, 2023Assignee: BEIJING CONST INSTRUMENTS TECHNOLOGY INC.Inventors: Hongjun Gao, Wei Ji, Xuecan Li, Gang Wang, Chunying Zhang, Jianjun Lin
