2. Product overview
2.1 Introduction to MGP260 series
Vaisala CARBOCAP
â
MGP260 Series Multigas Probes for Methane, Carbon Dioxide, and
Humidity Measurement are compact and durable in situ probes for methane (CH
4
), carbon
dioxide (CO
2
), and humidity (H
2
O vapor) measurements in demanding biogas processing
conditions. MGP260 series probes are Ex certified for use in Ex Zone 0 (parts inserted into
process) and Ex Zone 1 (parts outside the process).
MGP260 probes can be installed directly into raw process gas, removing the need for sample
treatment. Application areas include anaerobic digestion of industrial and municipal waste and
sludge from waste water treatment, landfill gas monitoring, activated carbon filter monitoring
in biogas treatment process, and CHP engine feed gas monitoring.
The MGP260 series proprietary infrared technology provides superior stability and
repeatability. Thanks to condensation elimination through probe heating and corrosion-
resistant steel and plastic materials, the IP66-rated instruments are highly robust and durable.
MGP260 series measurement output options include 3 analog current output channels (4 … 20
mA) and Modbus RTU over RS-485. The probes also provide a 4 … 20 mA Ex ia input for
connecting an optional external pressure or temperature sensor.
For easy-to-use access to configuration, diagnostics, and calibration and adjustment
functionalities, MGP260 probes can be connected to Vaisala Insight PC software with a USB
cable accessory.
