How to apply infrared combustible gas detector
Infrared combustible gas detector is a detector that responds to the concentration of single or multiple combustible gases.
The intelligent sensing transmitter used in the detector is a fully functional combustible gas sensing transmitter.
Application environment of combustible gas detector
Infrared combustible gas detectors are an ideal choice for the following application environments:
1. Frequent exposure to catalytic toxic gases;
2. Frequent emissions of highly flammable gases;
3. Hypoxic environment;
4. Detecting environments that are difficult to implement.
The application scope of combustible gas detectors includes:
Work platforms and drilling platforms, refineries, petrochemical plants, compressed natural gas and liquefied gas treatment, wastewater treatment, chemical plants, pump stations, thermal power plants.
1. There is no display when turned on. Membrane switch malfunction; Battery lead breakage: The battery voltage is severely insufficient.
2. When turned on, there is only a negative sign, and pressing the "voltage" button does not count. Voltage regulator power supply failure or short circuit on its output side.
3. The startup only has a decimal point. The sensing element has a damaged loop; Or a component in the bridge circuit may experience desoldering.
4. No alarm for exceeding the limit. Ring damage of the alarm: The alarm circuit is disconnected.
5. The accuracy cannot be adjusted to the standard gas sample. Serious dust accumulation in the explosion-proof cover; Sensor aging.
Repair requirements for combustible gas detectors:
1. It is prohibited to dismantle this instrument at will, and maintenance work should be carried out by trained professionals.
2. When a malfunction occurs during use, it is not allowed to dismantle and repair the machine underground.
3. Sensors and battery packs are special explosion-proof components that must be replaced as a whole after damage. Our factory provides spare parts and cannot substitute with other types of components.
The above are the common faults and maintenance methods of combustible gas detectors. After mastering these maintenance and analysis methods, everyone can try to repair the combustible gas detector by themselves, without the need to trouble professionals or companies for repairs.
