Scene automatic calibration system and method for integrative temperature transmitter

Abstract

The invention belongs to the temperature measurement technical field, and in particular relates to a scene automatic calibration system and a scene automatic calibration method for an integrative temperature transmitter. The scene automatic calibration system comprises a computer, a standard platinum resistance thermometer and an integrated control module. The standard platinum resistance thermometer and the element to be measured are respectively connected with a multifunctional electric measuring instrument of the integrated control module; the standard platinum resistance thermometer and the element to be measured are positioned in a work cavity of a constant temperature working range to be heated; the temperature increase of the constant temperature oven is automatically controlled by the computer through the preset program, the resistance value of the standard platinum resistance thermometer is collected in real time for monitoring the temperature change in the work cavity; the computer analyzes and processes the collected data according to the preset program for automatically generating the calibration report after that the temperature field reaches to the calibration condition. The scene automatic calibration system and the scene automatic calibration method for the integrative temperature transmitter have the beneficial effects that the difficulty of complex field calibration connection circuit and inconvenient to carry instrument is solved, the computer is adopted for executing automatic calibration, and the new market of the scene automatic calibration device of the integration temperature transmitter is developed.

Description

technical field [0001] The invention belongs to the technical field of temperature measurement, in particular to an on-site automatic calibration system and method for an integrated temperature transmitter. Background technique [0002] Temperature is a physical quantity that characterizes the degree of coldness or heat of an object. The process of obtaining temperature through various temperature measuring instruments is called thermometry. Temperature measurement is of great significance in industrial production, medical safety and other aspects. As an important temperature measuring instrument, integrated temperature transmitter has a wide range of application values. [0003] Instruments used for the calibration of temperature measuring instruments, especially integrated temperature transmitters, include standard platinum resistance thermometers and their supporting electrical measuring instruments, integrated temperature transmitter supporting electrical measuring instr...

Problems solved by technology

[0003] Instruments used for the calibration of temperature measuring instruments, especially integrated temperature transmitters, include standard platinum resistance thermometers and their supporting electrical measuring instruments, integrated temperature transmitter supporting electrical measuring instruments and their power supply modules, and portable constant temperature baths. Devices exist alone, and the connection lines are complicated and difficult to operate during the measurement process, and it is inconvenient to carry because the instrument is not integrated; and the calibration process requires manual temperature control, temperature field determination, data reading and processing, not only the workload is heavy, but also a lot of The Introduction of Uncertain Factors Seriously Affects the Quality of Measurement Work

The on-site automatic calibration device and automatic calibration method of the integrated temperature transmitter are still blank in the domestic market, and similar instruments and patents have not yet appeared
