A new monitoring system for toxic and flammable gases eliminates
the need for processors to install multiple fixed detectors, its
manufacturer claims.

Crowcon said its PGSi Programmable Monitoring System can detect toxic or flammable gases such as carbon monoxide, carbon dioxide and methane from multiple locations. "By doing away with the need for multiple fixed detectors, the sampling system significantly reduces installation and maintenance costs,"​ the company stated. Crowcon designed the system especially for carbon dioxide monitoring in breweries, distilleries and food processing plants. The system simultaneously monitors up to four different gases from up to 32 individual sampling points. Each sample line can be up to 3,280 ft long, and sample times for each monitoring point, which can be sequenced in any order, are individually adjustable, the company claimed. 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, the company sated. A dual pump arrangement is designed to ensure that samples reach the gas sensors as quickly as possible, the company stated. Filters, flow-fail devices, internal gas leak detectors and flame arrestors are all fitted as standard. The system is controlled from a Windows XP-based computer. The software displays and logs individual sample locations, gas levels, and alarms in tabular or graphical formats. It operates up to 32 relays, which activate alarm devices or send a signal to external control equipment. The system can be monitored remotely via an optional modem, allowing status checks and the uploading of datalog files.
