1.Flammable gas detectorsComposition:
It mainly consists of the following three parts:
1. Detector: collect flammable gas in the air and install it near the flammable gas release source;
2. Controller: display the oil and gas concentration, when the set value is reached, send out an alarm or other signal, generally installed in the manned duty room;
3. Connection part: refers to the armored cable or cable with metal sleeve to prevent electromagnetic interference, which transmits the signal of the detector to the controller.
When the detector detects the oil and gas in the air, the size of the oil and gas concentration is converted into a corresponding signal, which is transmitted to the controller by the connecting cable, and the controller converts the electrical signal into a digital signal, and displays the concentration value of the oil and gas on the liquid crystal display, but when the value is greater than the set value, the buzzer or warning light will send an alarm signal, or start the interlock system and turn off the release source.
II.Flammable gas detectorsInstallation Range:
Flammable gas detectorsIt is installed in flammable and explosive places where crude oil is produced, transported, stored and used, such as pump rooms, metering rooms, valve group areas, oil storage tank areas and other devices where crude oil leakage may occur. The specific installation location of the detector should be determined according to the type of flammable gas, process equipment, storage and transportation facilities, and the place of diffusion and accumulation of flammable gas, which can be installed both indoors and outdoors; Mounted on both the ground and rooftop, its detection range covers the entire hazardous area.
