Multi-gas analyzers
CAM module
Freely configurable sensor system for biogas measurement
The CAM – Compact Analyzer Module is a versatile solution for reliable biogas analysis. Up to 10 sampling points can be monitored and an integrated pump enables pressure-freeoperation. Overpressure protection and flow measurement are optionallyavailable.
For gas detection, the module supports up to three EC sensors, which can be operated in pulse mode to prevent overload, as well as an O₂ sensor. The main gas components are measured using modern infrared technology – either cyclically for CH₄ and CO₂ or continuously for CH₄, C₂+ and CO₂. A thermal conductivity detector (WLD) for H₂ measurement can beintegrated to extend the functionality .
