BSM-44D-TX
Multiaxial Bedrock Strain Transducers
Summary
Most suitable for analysis of stress conditions of bedrock natural ground
Designed for installation in a boring to detect strain in multiaxial directions inside bedrock, the BSM-44D-TX is useful to analyze stress conditions of the bedrock natural ground. Thus, it can be used for over-coring tests to measure bedrock stress changes or to seek initial stress conditions of the bedrock natural ground. By using a single unit of this transducer, three to six strain components can be measured, including one or two strain components in the axial direction of a boring and two to four strain components in a right-angled direction to the boring axis.
