Abstract
본 발명은 가수센서부에 연결된 마이컴에 의해 대기상태에서 감지한 가스센서부의 저항값과 측정가스를 흘렸을때의 가스센서부에서 감지한 전기적 신호를 연속적으로 측정하여 오차없이 감도변화를 정확하게 측정하도록한 가스센서 특성 측정장치에 관한 것으로, 챔버(4)내에 혼합기(3)에서 혼합된 가스가 유입될때 잡가스영향을 차단하지 못하고, 가스센서(5)의 전기적 신호를 검출하고, 감도를 감지하고자할대 마이컴에 의한 자동제어가 수행되지 않아 상기 가스센서(5)의 전기적 신호를 레코더(7)에 연속적으로 기록하지 못하는 문제점을 해결하기 위한 것이다.The present invention continuously measures the resistance value of the gas sensor unit detected in the air by the microcomputer connected to the mantissa sensor unit and the electrical signal detected by the gas sensor unit when the measured gas flows to accurately measure the sensitivity change without error. The present invention relates to a gas sensor characteristic measuring apparatus, which does not block the influence of miscellaneous gases when gas mixed in the mixer (3) flows into the chamber (4), detects an electrical signal of the gas sensor (5), and detects sensitivity. This is to solve the problem that the automatic control by the microcomputer is not performed and thus the electric signal of the gas sensor 5 cannot be continuously recorded in the recorder 7.
본 발명은 이와같은 종래 문제점을 해결하기 위하여 챔버에 자동압력 조절기 및 펌프를 연결하여 챔버내에 유입되는 측정가스 이외의 잡가스영향을 사전에 방지하고, 또한 챔버내의 가스센서에 A/D변환부와 연결된 마이컴을 연결하여 가스센서에서 감지한 대기상태에서의 저항값 변화 및 측정가스에 의한 전기적 신호를 자동연속적으로 여차없이 감도변화를 측정할 수 있게 한 것으로, 가스에 적용되는 모든 센서에 채용된다.The present invention connects the automatic pressure regulator and the pump to the chamber in order to solve such a conventional problem, to prevent the effect of miscellaneous gases other than the measured gas flowing into the chamber in advance, and also to the gas sensor in the chamber, By connecting the connected microcomputer, it is possible to measure the change of the resistance value in the atmospheric state sensed by the gas sensor and the electric signal by the measured gas automatically and continuously. It is adopted in all the sensors applied to the gas.
