Wall-mounted alcohol gas alarm is a fixed alcohol gas detector, which is mainly composed of two parts: a gas detector and a gas controller. The alcohol gas detector is installed in the detection site to detect the alcohol concentration, and the gas controller is installed in the duty room to analyze and display the alcohol gas concentration. When the alcohol concentration reaches a certain concentration, the alcohol gas controller will automatically remind the staff to take appropriate measures in time, so as to avoid the occurrence of important accidents. In order to ensure the accuracy of the detection of the alcohol alarm, it is necessary to operate in strict accordance with the relevant regulations during installation, so as to avoid the occurrence of accidents caused by inaccurate detection.
Item 1: The alcohol combustible gas alarm should be installed in a place where the gas is easy to leak, and the specific location should be determined according to the proportion of the detected gas relative to the air: 1. when the proportion of the detected gas is greater than the proportion of air, the gas detector should be installed at the distance from the ground (30 ~ 60)cm, and the sensor part is downward. 2. when the proportion of detected gas is less than the proportion of air, the gas detector should be installed at the distance from the ceiling (30 ~ 60)cm, and the sensor part is downward.
Item 2: In order to correctly use the gas detector and prevent the occurrence of the gas detector failure, please do not install in the following locations: 1, directly affected by steam, fume; 2, the air outlet, ventilation fan, door and other places with large air flow; 3, water vapor, water droplets (relative humidity ≥95%RH); 4, where the temperature is below -20℃ or above 50℃; 5. Places with strong electromagnetic fields.
Item 3: Fixed gas detector for one-to-one gas detection.
Alcohol gas detector uses natural diffusion method sampling, high precision, strong reliability, flame-proof design suitable for dangerous conditions 1, 2 area, small size, easy to install, the controller uses high-speed CPU processor, can quickly and accurately handle the system task, to ensure the reliability of the system, LED, LCD display screen, The detector's concentration and status can be displayed in real time, and the modular structure design is convenient for system maintenance, and the local monitoring can be realized by computer.
