Options
▪
Monitoring of Ambient Air:
A continuous monitoring of ambient air, such as for example for Methane (CH
4
) and Hydrogen Sulphide (H
2
S), can
also be realised via external ExTox-Transmitters.
▪
Change-over of measuring points:
The system can be changed over between 2 and maximum 6 (Special version: 12) measuring points. After each
measurement the gas inlet is cyclically changed over to the next measuring point. Control of course is done by
the control unit.
▪
Flame Arrestor
¯
IIG IIB3 (Standard) or
¯
IIG IIC:
When sampling in hazardous areas the gas flow inside the IMC is decoupled of the monitored process as far as
the danger of explosion is concerned. The flame arrestor is connected to the measured gas inlet. When returning
the measured gas into the process another flame arrestor at the measured gas outlet is necessary.
▪
Measured gas cooler including automatic removal of condensate:
Gas dehumidification by means of a Peltier cooler, temperature of measured gas at outlet: +5 °C
(Recommended for very high humidity content in measured gas.)
▪
Hydrophobic dehumidification of measured gas:
Dehumidification of gas is done via a chemical exchange process.
(Recommended for very high humidity content in measured gas.)
▪
Heating for enclosure with thermostat c5 to +30 °C :
Necessary for very low temperatures at the place of application. Formation of condensate inside the housing is
avoided when installing the IMC outside.
▪
ProfiBus
®
-Connection:
Measured values and messages can be transferred to a ProfiBus
®
via Interface.
(Further connections to superior
systems on request).
▪
Data Logger:
Measured values and messages are stored on a SD memory card. All data can be read out and processed on
every standard PC later on.

Customer specific modifications – Ask us!
Different biogas concepts also require different monitoring concepts. The modular design of our IMC-Systems al-
lows us to respond to your special wishes and requirements.
