Gas detector working principle

working principle
The combustible gas detector adopts high-quality gas sensor. The microprocessor combined with the precision temperature sensor can intelligently compensate the drift of the gas sensor. The environment adapts to a wide range, the work is stable, no need for debugging, and the ceiling mounting method is adopted. The installation is simple and the wiring is convenient. It is used for safety monitoring in places where there are flammable gases in homes, hotels, apartments, etc. It can detect natural gas, liquefied petroleum gas and artificial gas.
The detector operating voltage is DC powered. After the alarm, a pair of relay passive contact signals (normally open, normally closed and jumper settings) can be output to control the ventilation and ventilation equipment or to provide normally open or normally closed alarm contacts for other equipment.
When the concentration of flammable gas in the environment reaches the set threshold, an audible and visual alarm signal can be emitted, and the passive contact signal of the relay can be output.
When the ambient flammable gas concentration drops below the response threshold, the detector in the alarm state will automatically return to normal operation.

Light Duty Chain Conveyor

Light range of conveyors is developed to convey grains, seeds, pigments, additives and meal type of products where material is free flowing and less abrasive environment. Bush chain with bolted UHMWPE paddle is used to convey materials, which run on bottom plate and return brackets. UHMWPE bottom and top liners are available on request. Due to its design and product nature, these conveyors can operate at high chain speed.

Conveyor casings and bolt holes are cut using CNS laser machines and folded. These conveyors are specifically designed to reduce fabrication and assembly duration, which makes them very economical.

Chain conveyors can be designed in a horizontal, inclined, or in vertical arrangement. Conveyor`s bottom and side panels are made off 3mm folded galvanized sheets with 2mm top cover. Drive and tail units fitted with flanged bearing housings with lip seals, Plummer block bearing housing are also available on request.

Hardened head end and tail sprockets are mounted with keys.

Conveyor roller chains and standard sprockets are widely used for these applications.

Tail end comes with adjustable screw take up in standard design; self-cleaning tail end with screw adjustment on driven is available for food products.
