SensAir Combustible is an industrial grade fixed point gas detector with robust poison resistant sensor that maximizes sensor life and reduces cost of ownership. Advanced catalytic bead sensor technology detects a wide range of combustible gases. SensAir Combustible is housed in a rugged, explosion-proof aluminum or 316 stainless steel enclosure with variable mounting orientation options. A three-wire, 4-20mA output enables easy installation in retrofit or new applications with interface to common facility communication links.

Sulfides and Silicons are known to poison or inhibit standard catalytic bead sensors at concentrations as low as one part per million (1 PPM). Poisoned catalytic bead sensors are rendered ineffective and unable to detect gas. Advanced sensor technology used in SensAir Combustible significantly reduces the effects of poisoning, thereby minimizing the replacement of sensors and costs of ownership, making this product the ideal gas detector for chemical and hydrocarbon processing and manufacturing facilities.

The advanced SensAir Combustible catalytic bead sensor employs a pair of pellistors (catalytic beads) that provide uniform electrical resistance in clean air. An active pellistor “catalyzes” combustible gas when present while a reference pellistor compensates for changes in ambient environmental conditions. The difference provides an output that is accurate and linear. This advanced design provides excellent combustible gas sensitivity, rapid response, and extended sensor life.

SensAir’s advanced sensors combined with its simple, low maintenance design lowers operational expenses making it an ideal, cost-effective gas detector for industrial applications.
