maMoS

maMoS – modular stationary gas analyser

Small in size, yet very skilful analyser – it has the best capabilities/price ratio. maMoS is our alternative for large, intricate CEMS systems, as it does not fall behind them concerning functionality and abilities, and is far ahead in terms of expenses.
It has modular construction, and many add-ons, that makes it easy to adjust to a very specific, individual application.
Powerful PC software allows to adjust many aspects of the work with the analyser very individually (work schedule, analogue outputs' behaviour, data presentations, and more...)

  • Communication with PC via different interfaces (USB, LAN, RS485 and MODBUS).
  • Different work modes to select from (continuous measurements, work with scheduler, measurements triggered with digital input, “work in-turns” - allows to measure from two different sources, and more...).

Compact vs split configuration

Compact configuration

1_1

Compact configuration - analyser with gas dryer on a common mounting plate, all installed near the measurement place

Split configuration

1_2

Split configuration - analyser and gas dryer are installed on separate mounting plates, each equipped with its own power supply module.
Gas dryer is installed near the measurement place, analyser can be installed in a distance from the dryer (in the operation convenient place). Analyser can be far away from the dryer, as the gas in the between connection is suitably prepared for measurement.

Twin-split configuration with one dryer mounted on a separate plate.

1_2a

Twin split configuration - this version is based on compact configuration, but one MD3 dryer with its own power supply is added on a separate mounting plate.
Allows to perform measurements from two different locations (each dryer is installed near the measurement place). maMoS measures in turns - one cycle per location.

Twin split configuration - both dryers on separate plates

1_3

Twin split configuration - analyser and two gas dryers, each on its own mounting plate, each equipped with a power supply module.
Allows to perform measurements from two different locations (each dryer is installed near the measurement place). maMoS measures in turns - one cycle per location.

Complete and ready to operate maMoS unit

1_6

Configurations of the analyser’s gas channel

1_7

Analyser with a single gas channel is basic configuration of the device

1_8

The second (additional) gas channel is enabled for shorter time during the measurement phase. The additional gas channel is dedicated for the ”fragile” sensors, where they are protected against too long exposure to the gas. This way the life-time of the fragile sensors is prolonged.
Bio-measurement is a typical application for the double gas channel configuration - then the primary gas channel holds sensors CO2, CH4, O2, and the additional gas channel holds the H2S sensor that is recognised as a fragile one.

1_9

Analyser designed to work with overpressure with a single gas channel. Configuration can be used in installation with slight overpressure (<1.8bar)
