Gas detector troubleshooting

In the process of using the gas detector, the gas alarm user uses the air-harmonic and heating equipment to approach the flammable gas detector device. When the air-harmonic and heating equipment is used, if the cold and warm air flows directly through the body alarm, It is possible to form a body alarm, the platinum wire has a change in the electrical resistivity of the body, and the body alarm should be kept away from the air conditioner and the heating device to prevent the improper orientation from being caused. Users should also pay attention to electromagnetic interference during the process of using flammable gas detectors. The user uses the body alarm as much as possible to select a product that can be replaced by the sensor probe for ease of use.

First, the construction process is not standardized

If the construction process is not standardized, the flammable gas detector will be explored during the application process. For example, the flammable gas detector is not located in the vicinity of the device, and the device is adjacent to the exhaust fan. The leaky body cannot be dispersed enough to be adjacent to the flammable gas detector, so that the leakage danger cannot be ignited in time. Gas detectors detect. If the flammable gas detector is not grounded firmly, it cannot eliminate the electromagnetic disturbance, which will affect the voltage and present the problem of prohibition of exploration data. Therefore, the flammable gas detector should be grounded firmly during the construction process. The flammable gas alarm and the wiring terminal are arranged to be vulnerable to bumps or easy water inlets, forming an electrical circuit breaking or short circuit. It is necessary to use non-corrosive flux for welding, otherwise the joint will be corroded or line resistance will be added, which will affect normal exploration. Do not fall or throw the explorer to the ground. After the construction, debugging should be carried out to ensure that the body alarm is in normal working condition.You may need combustible gas detector from https://www.chinagasalarm.com/product/

Second, maintenance of the body detector to detect the body concentration

It is necessary to make the explorer and the test environment communicate, so the various polluting gases and dust in the environment can not be prevented from entering the surveyor, and the damage to the working conditions formed by the explorer is objective. The flammable gas detector The working environment is relatively harsh, and many devices are outdoors. Poor maintenance will result in errors in the exploration of the body alarm or no exploration. Therefore, cleaning and maintaining the flammable gas detector at regular intervals is an important task to prevent the onset of the problem. Grounding should be detected regularly, the grounding can not meet the requirements of the specification, or the grounding is not grounded, and the flammable gas detector is also susceptible to electromagnetic interference, which is a problem.

It is advocated that before the various instruments are used, the instrument should be tested with the standard gas to ensure that the instrument plays a real role in maintenance. The combustible gas alarm and the toxic gas alarm are also the same as other profiling instruments, which are measured by a relatively comparative method: the instrument is first calibrated with a zero gas and a normal concentration of gas, and the specification curve is stored in In the instrument, during the measurement, the instrument compares the electrical signal generated by the gas concentration to be measured with the electrical signal of the normal concentration, and calculates an accurate gas concentration value. Therefore, the instrument is zeroed at any time, and regular calibration of the instrument is an essential task to ensure accurate measurement of the instrument.
