汽油氣體檢測探測報警器

汽油在常溫下為無色至淡黃色的易流動液體，很難溶解于水，易燃，餾程為30℃至220℃，空氣中含量為74～123克/立方米時遇火爆炸，建議在汽油場所配置汽油氣體檢測（探測）報警器，防止爆炸、火災(zāi)事故的發(fā)生。

汽油氣體檢測（探測）報警器產(chǎn)品特點：

◆ 測量準(zhǔn)確：傳感器采用進(jìn)口氣體敏感元件，精度高，零點漂移小，抗中毒性能好。

◆ 防爆設(shè)計：可用于工廠條件的1、2區(qū)危險場合。

◆ 維修方便：傳感器采用數(shù)字化模組設(shè)計，現(xiàn)場更換時無需校零、標(biāo)定。

◆ 聲光報警：氣體檢測器可選配專用的防爆聲光報警器，實現(xiàn)現(xiàn)場聲光報警。

◆ 濃度顯示：氣體檢測器可選配液晶濃度顯示，現(xiàn)場實時顯示濃度。

Gasoline Gas Detect Alarm

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.
