Wireless gas sensors for CO (carbon monoxide) and NO 2 (nitrogen dioxide) monitor parking facilities, and can be applied to manufacturing lines, warehouses, and other facilities.

Measurement system using wireless gas sensor technology from MSR Electronic is reducing electrical installation costs in parking facilities as much 80%, and could readily be applied in manufacturing production lines and/or connected warehouses and loading docks.

Aimed at enclosed car parks, the system satisfies a variety of regulatory standards in nearly all countries, including UL 2075 in the U.S., VDI 2053 in Germany, and Norm in Austria. It consists of a receiver unit and up to eight wireless gas sensors. Up to eight receiver units (64 gas sensors) can be linked to the central analysis system on a local operating network bus. Sensors are placed every 400 to 500 sq m. Transmitter unit is integrated on the sensor board to create a compact and economical wireless device. Power comes from a standard battery with a three to four-year life.

Wireless gas sensors for CO (carbon monoxide) and NO2 (nitrogen dioxide) are currently available. These measure exhaust concentrations of gasoline and diesel vehicles in ambient air. Additional sensors are under development and are expected to be available by the end of the year. If specified exhaust concentration limits are exceeded, digital relay outputs in the detection system activates ventilators, warning lights, or horns to alert anyone in the structure to the presence of toxic fumes. The system also has applicability in NH3 cooling systems, for oxygen monitoring in laboratories, and on production lines.

MSR Electronic designs and produces gas technology (toxic, combustible, oxygen, refrigerant) for building automation and light industrial applications. Information about this application was provided by its U.K. representative, Slaney Direct Ltd .
