What are the characteristics of the portable combustible gas detector and how it works
1. Low power: Under the normal monitoring status of the equipment, the working time is ≥8 hours.
2. LCD display Using LCD display, it can visually display the on-site gas concentration.
3. Digital module design adopts high-speed CPU processing, automatic fault identification, automatic alarm, and automatic protection for high concentration exceeding the limit.
4. The accurate measurement sensor adopts imported gas sensitive components, which have the characteristics of high precision, high reliability, good gas selectivity, and strong anti-interference ability.
5. The battery has a long working life. High-performance rechargeable lithium battery is used, which has charging protection and low-voltage protection functions. Ensure reliable and long battery life.
The combustible gas detector is calibrated and produced according to the specific gas to be detected in the place when it is applicable, and it is a detector that responds to the concentration of a single or multiple combustible gases. As long as it is a place where flammable and explosive gases exist, a combustible gas detector is required. Precautions for installation of combustible gas detector:
1. Wiring should be done when the power is off, and the power should be turned on after confirming that the wiring is correct; the probe should be debugged by remote control when it is confirmed that there is no leakage of combustible gas on site.
2. The installation location should be selected within a radius of 1 meter near the valve, pipeline interface, gas outlet or the place where leakage is easy, as close as possible, but do not affect the operation of other equipment.
3. When used for large-area gas detection, a probe can be arranged in 20-50 square meters, which can achieve the effect of safety monitoring.
4. Installation height: when detecting gases lighter than air such as hydrogen, natural gas, and city gas, install it about 1 meter above the roof; when detecting gases heavier than air such as liquefied petroleum gas, use 1.5 to 2 meters below the ground meters or so to install.
5. The installation method can be roof hoisting, wall hanging or connecting pipes, etc., and the installation should be ensured to be firm and reliable. We have equipped with an infrared remote control to facilitate debugging and operation.
6. The on-site wiring should go through pipes, and the pipes used should meet the fire protection requirements. The pipes should be connected with the probes to meet the fire protection requirements.
7. When installing, the sensor should be fixed downward.
8. Shielded cables should be used for wiring, and the diameter of a single wire is greater than 1 square millimeter. The shielding layer must be grounded when wiring.
