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.
