BEH-C-S
Skin Friction Transducers

Summary

High immunity against external force (interference)
High safe vertical force, and hard to break down
These transducers are designed to measure skin friction resistance force between a sinking caisson and the ground. They can suitably be used to control settlement and posture of the caisson.

Features

●Model providing a desired skin friction force can be manufactured.
●For measurement under the same conditions as around the installation site, the BEH-C-S series is designed for concrete shells and the BEH-D-S series, for steel shells.
●Receive no adverse effect from water pressure changing while they are sinking.
