Система газовой сигнализации
The Salwico SW2020 system is of scanning (sequential) sampling type permanently installed for a number of sampling points. The gas detectors are common for all sampling points, allowing the use of high quality gas detectors with good accuracy and by its unique design it offers a possibility to connect any 4-20mA gas detector up to 4 in a system.
The Salwico SW2020 is intended for detection of explosive and toxic gases in pump rooms, cofferdams, pipe tunnels, stools, ballast tanks, slop tanks and other areas.
- Sampling time as a function of pipe length.
- Gas detectors (up to 4 ) connected for alarm condition.
- Alarm levels for low and high alarm for each detector.
- Clear text information.
