Problems solved by technology

[0004] However, in the prior art, the calibration method of manually comparing the products one by one and adjusting the potentiometer is usually used. The calibration takes a long time, the production efficiency is low, and the operation error rate is high, resulting in inconsistent product quality.

Abstract

The invention discloses a dust concentration sensor calibration system. The dust concentration sensor calibration system comprises a main control panel, a plurality of standard sensors and a plurality of calibration plates. The standard sensors are connected with the main control panel and used for measuring a first measured concentration value of dust in the environment; the multiple calibration plates are in communication with the main control panel. The dust concentration sensor calibration system is simple in production calibration operation, high in calibration efficiency and accurate in calibration, and therefore the qualification rate of a product is increased.

Description

technical field [0001] The invention relates to the technical field of sensors, in particular to a calibration system for a dust concentration sensor. Background technique [0002] The dust concentration sensor is a device that uses the MIE scattering theory to count or measure the mass concentration of suspended particles in the air. It is mainly used in dust workplaces. It can monitor and display the total dust concentration in real-time, on-site, and continuously. At the same time, it is connected with other dust suppression devices such as sprinkler spray to achieve the best effect of dust measurement and dust reduction. [0003] Due to the different dust concentrations in different workplaces, the light scattering coefficient is also different. In order to measure accurately, it is necessary to calibrate the sensor in different dust concentration environments during the production process, so as to check the proportional coefficient of the dust concentration sensor in d...
