Avoid electromagnetic influences when using a combustible gas detector
In order to ensure the measurement accuracy of the combustible gas detector, we should pay attention to its regular verification and calibration in the process of daily use of the combustible gas detector. In some places, the safety supervision bureau has strict requirements on the use of the combustible gas detector. Some require calibration once a month, some three months, and some one year.
Most places do not have strict requirements for the calibration of the detector. You can pay attention to it when you use it, and often perform a simple test on the instrument. If you find that the instrument is obviously insensitive, you can send it back to the seller for professional technology. Judgment and maintenance. The instrument in good condition should be sent back to the seller for appraisal after it has been used for more than 3 years to see if the instrument can still achieve the detection effect, and the professional technical guide will guide the use and maintenance.
The following environments should be avoided in the use of the four-in-one gas detector, including:
1. There are three main paths for the electromagnetic environment impact detector: 1) The disturbance of electromagnetic waves in the workplace; 2) The narrow pulse group on the power supply and other input and output lines in the fixed gas detector; 3) The static electricity generated by the human body.
, The use of flammable gas detector should also pay attention to avoid high temperature, high humidity, steam, oil fume, etc.
Explosive combustible gas detector. The explosion-proof level should not be lower than the corresponding level of the current specification. The waterproof and dustproof rating is . A number represents dustproof, which can completely prevent dust from entering, which is a high level in dustproof. The second number stands for waterproof, even if the body gets wet by sudden rain, you can refurbish it.
In addition, all kinds of gas detectors have their own fixed inspection range. Only within the specified inspection range can the correctness of the detection data of the gas detector be ensured, and the detected data beyond the detection range for a long time can be guaranteed. The values are inaccurate and cannot be used as correct data. Therefore, the gas detector can only be used within the specified range.
