IAS-MO 2000 SET
The IAS-MO 2000 Set system consists of the following main components:
y 1 MO 2000 Set optical microphone system
y 1 MZWW 2000 weather and wind protection
The IAS-MO 2000 Set system meets the requirements of the ATEX directive.
The MO 2000 H optical microphone consists of an opto-acoustic microphone
head which is fitted with a fixed 3 m double fiber optic cable. The fiber optic
cable is connected to the MO 2000 CU central unit. Power is supplied via an
external wide voltage range power supply unit.
The MO 2000 H is an omni-directional microphone designed for picking up air-
borne sound. The components of the MO 2000 H microphone head (outside
dimensions: 1/2
inch) are made of plastic suitable for permanent stationary
use in areas where aggressive substances (gases, salts, moisture) or radia-
tion are present. All components of the MO 2000 H microphone head are
metal-free, including the fiber optic cable feed.
The main areas of application of the optical microphone are acoustic mea-
surement and communication tasks in industrial environments and EMC-sen-
sitive areas as well as medical magnetic resonance imaging and magneto-
encephalographic measurement (MEG). Other applications are to be found in
the field of non-detectable acoustic surveillance.
