Problems solved by technology

[0007] However, in order to safely sense gas in this existing gas sensing device, the staff directly adjusts the sensing error of the output signal of the gas sensor installed in the chamber filled with a certain concentration of gas, so its error adjustment is subject to certain restrictions. There is a problem that the characteristic value of the sensor changes or the variable resistance changes due to a certain impact

Abstract

The invention relates to a gas induction error automatic control device, in which a gas sensor for the gas inductor is put in a chamber with a certain gas concentration and the measured value taken as the proper error value of the gas sensor is stored in the storage part. A set control part can automatically set the proper resistance quantity of the gas sensor.

Description

technical field [0001] The present invention relates to an automatic adjustment device for gas induction error, in particular to a method for placing a gas sensor used for a gas sensor in a chamber with a certain gas concentration, and regarding the measured value as the inherent error of the gas sensor The value is stored in the storage unit, and the setting control unit (40) automatically sets the gas sensing error automatic adjustment device of the intrinsic resistance value of the gas sensor. Background technique [0002] Generally, gas (GAS) is supplied to gas appliances such as boilers or gas stoves through pipes, and a certain amount of gas. This kind of gas is easy to leak through the cracks of the pipeline and cause a fire, or the toxic gas after burning flows into the outdoor or indoor, which constitutes a safety hazard of toxic gas. [0003] With the devices that use natural gas (LNG) and propane gas (LPG) as fuel, the gap gas passing through the pipes is leaked ...
