BER-A-12S
Wall-surface Soil Pressure Transducer

Summary

Suitable for the chamber soil pressure of a shield machine, or backfill pressure measurement.
BER-A-12S/58S is an soil pressure transducers of the load cell type designed not to be subject to the influence of a structure bending.These are suitable for surface-of-a-wall soil pressure measurement.ince the 2-model (12, 58) preparations of these are made, they can choose the model united in the installation direction.

Features

●Wear of the pressure sensing surface does not affect output or initial values.　
●Load cell-based design is less affected by bending effects.
●This is for granular material pressure measurement whose particle diameter is about φ10.
