Options 

 

Monitoring of ambient air: 
A continuous monitoring of ambient air, such as for example for Methane (CH

4

) and Hydro-

gen Sulphide (H

2

S), can also be realised via external ExTox-Transmitters. 

 

Switching between measuring points (types Biogas2 and KAT): 
Determination of gas composition at different measuring points temporally one after an-
other. Supplementation of switching between measuring points forms a cost saving alterna-

tive to using several IMC. One single IMC performs the analysis one after another for the 
different measuring points. Switching can be done cyclically or externally controlled. The 

IMC-4D can cover up to four, the IMC-8D even up to six measuring points (special types: 
twelve).  

 

Flame Arrestor 

¯

 IIG IIB3 (Standard) or 

¯

 IIG IIC: 

When sampling in hazardous areas the gas flow inside the IMC is decoupled of the moni-
tored process as far as the danger of explosion is concerned. The flame arrestor is con-

nected previous to the measured gas inlet. When returning the measured gas into the proc-
ess 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 100 W 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. 

ƒ

 

Preparation for Installation outside: 
Rain protection covers for housing fans and/or internal control unit 

 

ProfiBus

®

-, ModBus

®

- und Ethernet-Connection: 

Measured values and messages can be transferred to a superior PLT-System via Interface.  

 

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 applications also require different monitoring concepts. The modular design of our 
IMC-Systems allows us to respond to your special wishes and requirements.
