1 Introduction
The multiplexers in the HBM series M408, M416 enhance the measuring
capability of the optical interrogators. They consist of a series of highly reliable
high-speed optical switches that are seamlessly integrated in the data
acquisition of the interrogator. The multiplexers can upgrade a four channel
evaluation device to eight or sixteen channel operation while maintaining the
same wavelength accuracy and resolution, and deterministic realtime data
acquisition.
1.1 Features
•
Upgrades four channel interrogators to eight or sixteen channel operation
(except SI410 and DI405)
•
Realtime data acquisition
•
Reliable high-speed optical switching
•
Excellent thermal and service life stability
•
Seamless integration with associated interrogator
1.2 Applications
•
Strain measurements in civil engineering, including bridges, roads and
dams
•
Continuous monitoring of structural condition of ships and airplanes
•
Underground pressure and temperature measurements in oil bores
•
Deep sea oil platform riser monitoring
•
Electromagnetically affected environments
•
Fields with high energetic potential
•
High voltage
•
In critical and/or radioactively contaminated areas in chemically aggressive
or corrosive environments
In combination with the optical interrogators in the series SI-.. and DI-, the
system can interrogate up to 208 optical sensors across a 208 nm full range
with a frequency of 0.25 Hz to 500 Hz. The interrogators facilitate the control
of the multiplexer and make the multiplex system data exclusively available
via the Ethernet remote control interface.
