Toxic And Flammable Gases Easily Monitored
Toxic or flammable gases such as carbon monoxide, carbon dioxide and methane can be easily monitored from multiple locations with Crowcon’s new PGSi Programmable Monitoring System.
Monitoring up to four different gases at once, from up to 32 individual sampling points, the PGSi is ideal for applications such as carbon monoxide monitoring in car parks and tunnels, carbon dioxide monitoring in breweries, distilleries and food processing plants, or monitoring methane leaks from the heating systems of buildings. By doing away with the need for multiple fixed detectors, the sampling system significantly reduces installation and maintenance costs.
Each sample line can be up to 3280 feet (1000m) in length and sample times for each monitoring point are individually adjustable and can be sequenced in any order. A dual pump arrangement ensures that samples reach the gas sensors as quickly as possible. Filters, flow-fail devices, internal gas leak detectors and flame arrestors are all fitted as standard to ensure safe and reliable operation at all times.
The system is controlled by a PC using Windows XP-based software. A screen displays individual sample locations, gas levels and alarms. It operates up to 32 relays (which activate alarm devices or send a signal to external control equipment) and provides comprehensive data-logging facilities, with gas data is displayed either in tabular or graphical formats. The PC can be monitored remotely via an optional modem, allowing status checks and the uploading of datalog files. The system can be supplied with a PC or can operate with a PC supplied by the user.
