Gasoline at normal temperature, is a colorless or light yellow, free running liquid, hard to dissolve in water, inflammable, boiling range 30℃~220℃. The content of gasoline in air is between 74 and 123 g per cubic meter, fire star causes explosion. Gasoline gas alarm should be configured in gasoline site, taking precautions against explosion and fire.
Gasoline gas alarm consisting of gas detector and gas controller, is widely used in oil chemical lines (such as oil station, gas station, chemical industry, oil depot), monitoring the leakage, guarding the safety of body and property.
When the gasoline gas is detected, the detector turns gas signal into voltage signal or current signal, then sends the signal to the controller that displays the percentage concentration value. If the concentration exceeds the set value, the controller sends audible and visual alarm. The operator on duty adopts timely safety measures, avoiding burning explosion.
Feature of gasoline gas alarm
1. Accurate measurement: sensor with imported gas sensory unit, high precision, less zero shift, strong anti-poisoning.
2. Explosion-proof design: suitable for 1-area and 2-area dangerous site in firm.
3. Maintenance-free: sensor designed with digital module group, no need to zero setting and calibration.
4. Audible and visual alarm: gas detector if equipped with explosion-proof audible and visual alarm, sending audible & visual alarm on the spot.
5. Concentration display: gas detector if equipped with LCD, displaying the concentration on the spot.
