Biogas 401
Multi-Channel Gas Analyser
Application
The Biogas analyser monitors either continuously or intermittently, the gas components contained in the Biogas and optionally, monitors the surrounding air to provide an early warning of dangerous, explosive and non-combustible gases and vapours.
Features
- Use of various types of measurement sensor
- Direct indication of a warning state on an LC-display with coloured background lighting
- Menu-assisted operation via 2 keys
- 3 alarm levels, independently adjustable from 5 -100% of the test range selected
- 3 floating alarm outputs for driving external warning and control equipment
- Floating contact connections for fault and mains failure
- Serial interface output, RS 232 or RS 485
- 4-20 mA current interface
- Various types of housing available, e.g. 19" rack system, wall-mounting cabinet
- Up to 6 measurement channels per unit
- 1 card as Master, for controlling intermittent operation Biogas measurement time and test interval
- Extreme service reliability
- Low current consumption
- Peltier cooling element with condensate pump
- Flow-through adjustement
- Gas components - filter system and conditioning
- Water sensor for the detection of condensate break-through
-
Modular construction
- Monitoring of more than one measuring point possible
Fields of Application
- Monitoring of Biogas components
- Warning of explosive gas mixtures
