Abstract

Lessons learned during application of time domain reflectometry sensor cables to monitor deformation in rock and soil were presented. In the area of connector accessibility it was learned that, connections between different cables were a weak link, and should be made as robust and water proof as possible. If cables were interrogated manually with a Tektronix 1502 cable tester, it was required that they should be equipped with a SP232 module to acquire digital records.
