Zero-position adaptive device and method for electrochemical sensor

Abstract

The invention provides a zero-position adaptive device and method for an electrochemical sensor. The device comprises an air-inlet module, a check valve, an air pump, an electrochemical sensor module,a power supply module, a core processing module and a discharging module, the air-inlet module is separately connected with the air pump and the electrochemical sensor module, the check valve is arranged between the air-inlet module and the air pump, the air pump is separately connected with the electrochemical sensor module, the core processing module and the power supply module, the electrochemical sensor module is separately connected with the core processing module, the power supply module and the discharging module, and the power supply module is also connected with the core processing module. According to the zero-position adaptive device and method for the electrochemical sensor, once zero-position drift occurs in a usage process of the sensor, adaptive calibration can be rapidly realized, and zero-position deviation is avoided.

Description

technical field [0001] The invention belongs to the technical field of sensor measurement, and in particular relates to a zero-position adaptive device and method of an electrochemical sensor. Background technique [0002] Due to its own principle and characteristics, the electrochemical gas sensor will have a certain zero drift after a period of use, resulting in inaccurate test values ​​and misjudgment of faulty gas detection. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a zero position self-adaptive device and method for electrochemical sensors, once the zero position is found to drift during the use of the sensor, it can be quickly self-adapted and calibrated to avoid zero position deviation. [0004] The present invention is achieved like this: [0005] A zero position self-adaptive device of an electrochemical sensor, comprising an intake module, a check valve, an air pump, an electrochemical sensor mod...
