Application

The GAS 306 system is designed to monitor gas levels from a number of sample points, targeted at situations where the positioning of conventional gas sensors may not be practical. This may be due to equipment security, cable routing, access for detector head installation/maintenance, harsh environment or a cost-effective means of monitoring designated hazardous areas, typically – tunnels, marine applications, underground/high-level voids, process control, landfills, multi-storey car parks, brewing, horticulture, superstore multi refrigeration units.

Operation

A central control unit sequentially extracts gas samples via fixed sample lines for a timed period. A high-rate sample is taken by the main pump, during which a reduced-rate sample is passed across the sensor device.

The central unit provides gas level readouts with two alarm trip points per line, providing a range of signal outputs for annunciator and control functions.
