Calibration system of NDIR gas sensor

Abstract

The utility model relates to the technical field of sensor calibration, in particular to a calibration system of an NDIR (Non-Dispersive Infra-Red) gas sensor, which comprises a computer, a serial server, a relay module, a gas source group, a mass flow controller, a high-low temperature box, a gas analyzer and a calibration tool frame group for broadcasting calibration. The to-be-calibrated NDIR gas sensor is detachably mounted on the corresponding calibration tool plate and is in communication connection with the calibration tool plate; a storage medium is arranged in the NDIR gas sensor and is used for storing calibration data; the computer is in communication connection with the relay module, the gas analyzer, the mass flow controller, the high and low temperature box and the calibration tool plates through the serial port server. According to the utility model, simultaneous calibration of a plurality of NDIR gas sensors can be conveniently realized in mass production, and a lower-carbon green production environment is realized. 本实用新型涉及传感器标定技术领域，具体涉及一种NDIR气体传感器的标定系统，包括：计算机、串口服务器、继电器模块、气源组、质量流量控制器、高低温箱、气体分析仪和用于广播标定的标定工装架组。待标定NDIR气体传感器可拆卸地安装在相应的标定工装板上，并与其通信连接；NDIR气体传感器内部具有存储介质，用于存储标定数据；计算机通过串口服务器分别与继电器模块、气体分析仪、质量流量控制器、高低温箱和各标定工装板通信连接。本实用新型可以方便地在大批量生产中实现多个NDIR气体传感器的同时标定，实现更低碳的绿色生产环境。
