The MDX400T-X is a multi-channel data acquisition unit for Fibre Bragg Grating (FBG) sensors for measurement in harsh environment. It is available with 4 optical channels that are capable of sampling data at a frequency of 100Hz per channel for measurement of maximum of 64 sensors simultaneously. The MDX400T-X is capable of accepting almost all types of FBG sensors. It is an ideal choice of instrument to measure FBG sensors without having to purchase expensive signal conditioners. This multi-channel unit also offers advanced connectivity to interface with TCP-IP and CAN-open protocols.
