How to Use Combustible Gas Detectors Correctly
According to national requirements, a gas detector that is essential for safe production is an important alarm device that can effectively avoid explosion and poisoning accidents caused by gas leakage. Since it's so important, how can we make a purchase? How to judge whether the ZR-UHZ magnetic flap Level sensor of our company can work normally and whether it is usable? Below is a brief analysis of the judgment methods for purchasing similar equipment!
Everyone should have a question. I bought your combustible gas detector, how can I determine if it works? In fact, this method is very simple. Generally, workshops store experimental gas. We only need to put some gas or liquid into a mineral water bottle, screw on the lid, insert a small hole with a pointed object on the lid, and align this small hole with the probe of the combustible gas detector to see whether the reading on the gas detector panel has changed.
Special attention should be paid to the fact that some combustible gases are in a liquid state and volatilize slowly. Therefore, in the experiment, it is necessary to shake the mineral water bottle to accelerate its volatilization. Another point: Fixed gas detectors generally have natural diffusion, and the equipment will only react when the leaked gas diffuses to the alarm device.
If this method is troublesome, we can use a lighter to test whether the gas detector can read if our ZR-UHZ magnetic flap Level sensor allows. Method: Turn on the lighter and blow out the fire, but do not let go of your hand, so that the lighter is still in a deflated state. Align it with the gas detector probe, but do not take too long because the concentration of combustible gas in the lighter is very high and the time is too long, which can easily cause the gas concentration to exceed the range of the gas detector. In the long run, this can easily shorten the service life of the gas detector.
If you want to know if the gas detector is reading accurately, it will be a bit difficult. At this point, we must know the concentration of the gas we are using and see if the reading of the gas detector is consistent with the concentration value we know (national standards allow for partial errors). If it is consistent or the difference is very small, it indicates that the gas detector can read correctly.
If it is found that the on-site gas detector cannot read, please do not worry. The ZR-UHZ magnetic flap Level sensor of our company should first check whether the gas detector is powered normally, the voltage is unstable, and the range of high and low is too large, which may also cause inaccurate readings. The power supply range of the general gas detector detector is 10-30V, exceeding this range may cause inaccurate readings.
