Diesel oil gas alarm composed of gas detector and controller, widely used in petrochemical industries,such as oil,gas,chemical industry,tank farm,etc., moinitoring the gas leakage in dangerous sites, guarding the safety of body and proerty.
Diesel oil gas alarm with special detector of catalytic combusion, monitering in real time the gas concentration of diesel oil. When the gas exists in the site, the detector turns gas signal into voltage signal or current signal, then sends to the controller which displays in real time the gas concentration. If the concentration over the set value, the controller sends audible and visual alarm, the operator in duty takes in time the safety steps to avoid the flammable and combusible accident.
Feature of Diesel oil 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 for spot replacement.
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.
