How to solve the fault of the combustible gas detection instrument
There are two types of combustible gas detection instruments: catalytic type and infrared optical type. They are detectors that respond to the concentration of single or multiple combustible gases. In the process of using the combustible gas detection instrument, users will also encounter some failure problems, so we also need to master the methods of dealing with failures in use.
In the process of using the detection instrument, the user should install the air conditioner and heating equipment close to the combustible gas detection instrument. When using the air conditioner and heating equipment, if the cold and warm air flows directly through the combustible gas detection instrument, it may cause combustible gas detection. The resistivity of the platinum wire of the detection instrument changes and there is an error. Therefore, the combustible gas detection instrument should be kept away from air conditioners and heating equipment to avoid malfunctions caused by improper setting.
Users should also pay attention to preventing electromagnetic interference when using the flammable gas detection instrument. The installation position, installation angle, protective measures and system wiring of the combustible gas detection instrument should be protected from electromagnetic interference. There are three main ways for the electromagnetic environment to affect the combustible gas detection instrument: electromagnetic interference in the air, narrow pulse groups on the power supply and other input and output lines, and human body static electricity.
When using the flammable gas detection instrument, users should pay attention to the factors that may cause failure, such as dust, high temperature, humidity, rain, etc. When an exhaust fan needs to be installed in the field where the combustible gas detection instrument is installed, if the exhaust fan is installed adjacent to the combustible gas detection instrument, the leaked combustible gas will not fully diffuse to the vicinity of the combustible gas detection instrument, resulting in failure to detect in time. Yi missed the fighter.
In addition, users should also pay attention to the setting of flammable gas detection instruments in explosion-proof places. For example, Class A workshops that emit flammable gas should choose explosion-proof flammable gas detection instruments, and the explosion-proof level should not be lower than the corresponding explosion-proof level requirements of the current specification.
Users using flammable gas detection instruments should also pay attention to avoid places where high temperature, high humidity, steam, and oil fumes can be reached. Do not place objects or hang objects on the testing instrument. The installed flammable gas detection instrument cannot move the position of the device arbitrarily.
When using combustible gas detection instruments, users should try to choose products with replaceable sensor probes for ease of use.
