Overview
TS 21 I-HC is LPG gas detector system for protection against gas leakage. The system is designed
to detect gas leakage in the industrial premises with the help of gas sensor. The system is kept at
the user premises. It also detects presence of combustible gases like CNG, LNG. The gas detecting
sensor is kept inside Central Mining Research Institute (CMRI) certified flameproof enclosure. It is
a solid state semiconductor device that reacts to the presence of flammable gas. Microprocessor
based system reads sensor output and indicates the concentration of gas in atmosphere. It is
measured in % LEL (Lower Explosive Limit).
It is useful in variety of locations like LPG / CNG/ LNG gas storage areas, LPG bullets and banks,
plant locations, hotel kitchens, industrial canteens, gas filling stations and so on.
