What are the main things to pay attention to when using a gas detector?
First, to detect gas concentration, the detector must communicate with the detection environment. Therefore, it is inevitable that various polluting gases and dust in the environment enter the detector, and the damage to the working conditions of the detector is objective. Yes, the working environment of combustible gas detectors is relatively harsh, and many of them are installed outdoors. Improper maintenance will lead to errors in the detection of flammable gas detectors or no detection. Therefore, regular cleaning and maintenance of flammable gas detectors is an important task to prevent malfunctions.
Grounding should be checked regularly. If the grounding does not meet the standard requirements or is not grounded at all, the flammable gas detector will be susceptible to electromagnetic interference and cause malfunctions.
Second, when users of gas alarms use gas detectors, the resistivity of the platinum wire of the combustible alarm may change and errors may occur. Users should also pay attention to preventing electromagnetic interference when using flammable gas detectors. The installation location, installation angle, protective measures and system wiring of the body alarm should be protected against electromagnetic interference. When using flammable gas detectors, users should pay attention to factors that may easily cause malfunctions, such as dust, high temperature, moisture, etc. When an exhaust fan is installed in a site where a combustible gas alarm is installed, and the combustible gas detectors are placed adjacent to each other, the leaking combustible gas will not be able to fully diffuse to the vicinity of the combustible gas alarm, resulting in failure to detect in a timely manner and causing delays. Users should also pay attention to avoid places where high temperature, high humidity, steam, and oil fumes can reach when using flammable gas detectors. Do not place or hang objects on the detector. The installed flammable gas detector cannot be moved arbitrarily. Users who use body alarms should try to choose products with replaceable sensor probes for ease of use.
Third, irregular construction processes may cause flammable gas detectors to malfunction during use. If the flammable gas detector is not located near the flammable parts of the equipment that are prone to leakage, or is installed adjacent to the exhaust fan, the leaking flammable objects cannot fully diffuse to the vicinity of the flammable gas detector, thereby preventing the leakage hazard from being flammable in a timely manner. Sexual gas detector detection. If the flammable gas detector is not reliably grounded and cannot eliminate electromagnetic interference, it will inevitably affect the voltage and cause inaccurate detection data. Therefore, the flammable gas detector should be reliably grounded during construction. Combustible gas alarms and wiring terminals are installed in places that are prone to collision or water intrusion, causing electrical circuit breakage or short circuit. Welding must use non-corrosive flux, otherwise the joints will be corroded and disengaged or the circuit resistance will increase, affecting normal detection. Do not drop or drop the detector to the ground. After construction is completed, debugging should be carried out to ensure that the body alarm is in normal working condition.
It is recommended that before using various instruments, the standard gas used for the instrument should be tested for response to ensure that the instrument truly plays a protective role. Combustible gas alarms and toxic gas alarms, like other analytical and detection instruments, are measured using a relative comparison method: first use a zero gas and a standard concentration gas to calibrate the instrument, and obtain a standard curve stored in In the instrument, during measurement, the instrument compares the electrical signal generated by the gas concentration to be measured with the electrical signal of the standard concentration to calculate the accurate gas concentration value. Therefore, zeroing the instrument at any time and calibrating the instrument frequently are essential tasks to ensure accurate measurement.
