What are the main precautions in the use of gas detectors?
First, to detect the gas concentration, the detector must communicate with the detection environment, so it is unavoidable for various polluting gases and dust in the environment to enter the detector, and the damage to the working conditions of the detector is objective In fact, the working environment of flammable gas detectors is relatively harsh, and many of them are installed outdoors. Poor maintenance will lead to errors or non-detection of the body alarm. Therefore, regular cleaning and maintenance of combustible gas detectors is an important task to prevent failures.
The grounding should be checked regularly. If the grounding does not meet the standard requirements, or is not grounded at all, it will also make the flammable gas detector susceptible to electromagnetic interference and cause malfunctions.
Second, when the gas detector user uses the gas detector, the resistivity of the platinum wire of the combustible detector may change and cause errors. Users should also pay attention to preventing electromagnetic interference during the use of the flammable gas detector. The installation position, installation angle, protective measures and system wiring of the body alarm should prevent electromagnetic interference. When using the flammable gas detector, users should pay attention to factors that may cause failures, such as: dust, high temperature, humidity, etc. When an exhaust fan needs to be installed in the place where the flammable gas alarm is installed, the flammable gas detector is set adjacent to it, and the leaked gas will not be able to fully diffuse to the vicinity of the gas alarm, resulting in failure to detect in time and delaying the battle. Users should also pay attention to avoid places where high temperature, high humidity, steam, and oily smoke can reach when using the flammable gas detector. Do not place or hang objects on the detector. The installed flammable gas detector cannot move the position of the device arbitrarily. Users should try their best to choose products with replaceable sensor probes when using body alarms for ease of use.
Third, irregularities in the construction process will cause the flammable gas detector to detect failures during use. If the flammable gas detector is not installed near the flammable gas detector, or it is installed adjacent to the exhaust fan during installation, the leaked flammable gas cannot be fully diffused near the flammable gas detector, so that the dangerous leakage cannot be promptly detected by the flammable gas detector. Gas detector detection. If the flammable gas detector is not reliably grounded and electromagnetic interference cannot be eliminated, the voltage will be affected and the detection data will be inaccurate. Therefore, the flammable gas detector should be reliably grounded during construction. The flammable gas alarm and connection terminals are located in places that are prone to collision or water ingress, causing electrical circuit breaks or short circuits. Non-corrosive flux must be used for welding, otherwise the corrosion at the joint will separate or increase the line resistance, which will affect the normal detection. Do not drop or drop the detector on the ground. Debugging should be carried out after construction to ensure that the body alarm is in normal working condition.
