Problems solved by technology
However, the explosion-proof touch screen is expensive, which causes the material cost of the explosion-proof oxygen analyzer to be too high, which is not conducive to cost control for manufacturers
Secondly, the software design of the instrument using the explosion-proof touch screen is more complicated and cumbersome
In addition, the user needs to perform multiple operation steps such as menu selection and setting during on-site calibration, so the operation is more complicated

The invention provides a mechanical calibration device of an oxygen analyzer. The mechanical calibration device comprises calibration potentiometers used for calibrating the oxygen analyzer and an operatingmechanism used for rotationally operating the calibrationpotentiometers; the calibration potentiometers are arranged on a casing of the oxygen analyzer and extend out of the casing; the operating mechanism is arranged on the protective casing of the oxygen analyzer, the oxygen analyzer is arranged in the protective casing, and the operating mechanism is in operational connection with the calibration potentiometers, so that the calibration potentiometers are rotationally operated. The independent mechanical calibration device is designed on the protective casing of the oxygen analyzer andis operationally connected with the calibration potentiometers arranged in the casing, so that a user can complete online calibration by the mechanical calibration device arranged outside the protective casing, and the calibration process is convenient and efficient. A display window part of the oxygen analyzer only needs to adopt common explosion-proof glass meeting related explosion-proof criteria, and therefore, the cost is greatly reduced under the condition that the explosion-proof requirement is met.
Description
technical field [0001] The present invention relates to the technical field of oxygen measuring equipment, and more specifically, relates to a device for calibrating oxygen measuring equipment. Background technique [0002] Zirconia oxygen analyzer is a new type of oxygen measuring instrument developed in recent years. Because its sensitive probe can be directly inserted into the flue for detection, and has the characteristics of simple structure, high precision, and rapid response to changes in oxygen content, it is widely used to measure the oxygen content of flue gas in various boilers and kilns . In addition, the zirconia oxygen analyzer can be easily matched with the regulator to form a closed oxygen quantity control system to realize low-oxygen combustion control, so as to save energy and reduce environmental pollution. Therefore, its application in actual production is more and more extensive. [0003] The zirconia oxygen analyzer consists of two parts: an oxygen m...
