BJ-AT - Joint Transducers:
Suitable to check concrete blocks for an opening at the joint or cracks initiated mainly by temperature change
Mounting fixtures are available to measure an opening between a hydraulic pipe and backing concrete, as well as to use them as ordinary displacement transducers to check for deformation of blocks at dam monitoring areas or to detect displacement of rock-bed.
For embedment in concrete, the dedicated receptacle CJS-1C is embedded in advance in a preceding block and the joint transducer is installed to the next block.
Embedded across a joint of adjoining concrete blocks, the BJ-AT series joint transducers measure an opening between blocks. A temperature measuring function enables simultaneous measurement of displacement and temperature. In addition, for measurement of cracks of concrete or rock-bed, a dedicated receptacle allows embedment in concrete and mounting legs or fixtures enable surface installation.
