Problems solved by technology

The temperature verification system adopts the 98th edition of the old national standard, and the thermal resistance verification adopts the three-wire system standard. After the introduction of the new version of the national standard, it is required to use the method of combining the three-wire system and the four-wire system. The accuracy control of the original detection system has been far behind. Require

Abstract

The invention discloses a temperature verification device system and a detection method. The temperature verification device system comprises a computer, first and second detection hosts and first andsecond power regulators; the computer is connected with the first and second detection hosts via communication connecting lines; the first and second detection hosts are connected with the first andsecond power regulators respectively; the computer emits a control instruction to the detection hosts; and the detection hosts receive a computer instruction and then control the power regulators to execute corresponding running programs. The system and communication stability is improved, and thermocouple detection and thermal resistance detection can be carried out synchronously but independently via two temperature detection control systems; and a honeycomb portable temperature component verifier can take heat away rapidly in the heat radiation detection process, the real-time temperature in the furnace cavity can be observed, and proper time to take the temperature component can be obtained accurately.

Description

technical field [0001] The invention belongs to the field of temperature calibration, and in particular relates to a temperature calibration device system and a detection method of the temperature calibration device system. Background technique [0002] The existing laboratory temperature control system consists of a computer, SDT2000 mainframe, a single-group digital meter, a single-group power regulator, a double-calibration furnace, and a freezing point device for the oil tank and water tank. At the same time, check the thermal resistance. At this time, the oil tank, water tank and freezing point device are in an idle state. Moreover, the temperature at the calibration point of the thermocouple is very high and the temperature rises slowly, and different indexing elements must be bundled into the furnace in batches. After the calibration is completed, the next indexing element must be restored to normal temperature. The tube wall of the verification furnace is made of cl...
