The CEN Series wireless gas detection and control panel uses pneumatic sampling to bring gas from each sensing location back to the central panel. The advantage of pneumatic sampling systems is the ability to filter the air stream at both the sensing location and at the panel to remove suspended particulate and other solid contaminants. The filtration process keeps the sensors clean and extends their lifespan, improving performance and saving money for the building operator. Since one sensor for each gas can be shared among multiple sampling locations, lower servicing costs result since fewer sensors are replaced at service intervals when compared with purely electronic gas detection systems.
