BJB-C-S,D-S,E-S
3 models are available for selection of the most suitable one.
The BJB-C-S, BJB-D-S and BJB-E-S series displacement transducers are used as detectors for measurement of rock-bed displacement and ground settlement. Varieties of models are available for selection of the most suitable one based on the measuring range, dimensions and field situations.
?? BJB-C-S series is suitable for ordinary measurement of rock-bed displacement.
?? BJB-D-S series is available with high rated capacities and is suitable for measurement of the settlement of soft ground.
?? Slender BJB-E-S series is suitable for embedment in a boring and for rock-bed displacement measurement in NATM
