MLTDR-W-50S
The MLTDR-W-50 is a datalogger designed to automate monitoring of up to 8 coaxial cables embedded in a slope or borehole for deformation monitoring. It contains a control module, TDR interface and, optionally, an 8 channel coaxial cable multiplexer.
It is equipped with an interface to read Vibrating Wire gages. These gages are typically used to monitor pore pressures along the length of the installed TDR cable. The datalogger provides connection for 2 Vibrating Wire gages, a Canary Systems® MicroMux or MiniMux multiplexer may also be installed to expand the measurement capability to 5 or 17 instruments. A 50AHr lead-acid battery provides power, and is recharged either through a 40W solar panel or an AC power connection.
Communications are possible via a wireless or wired network interface. For wireless networks, a high performance ultra wide band log periodic antenna is supplied, including a lightning surge protector. An SGX 5150 is used for the Wi-Fi network interface.

Description
Time Domain Reflectrometry (TDR) is increasingly being used in geotechnical applications for deformation monitoring in soils and concrete. It provides accurate location information for faults and can provide indication of the static or dynamic nature of the faults. It is typically used to monitor slope movement of embankments including highway cuts, rail beds, bridge abutments and open pit mines.
In TDR applications the signal is an electrical pulse broadcast down a coaxial cable, and changes in the impedance of the cable, either inductive or capacitive, cause reflections to be returned to the signal generator. The resultant reflections are measured and presented as a function of time, the time is translated to distance based on the known propagation velocity of the cable being utilized. In geotechnical applications the cable typically takes the form of a rugged coaxial cable with a diameter of 12mm (0.5”). The cable is usually grouted into a borehole drilled into the embankment to be monitored. Any movement of the embankment will crimp the cable, and the reflections indicate approximate magnitude of the crimp and the location. The resolution is related to the number of samples of data being collected.
