BER-A-15S
Wall-surface Soil Pressure Transducer

BER-A-15S

Summary

Suitable for surface-of-a-wall soil pressure measurement of a small shield machine.
This is the small and lightweight wall-surface soil pressure transducers which harnessed the feature of BER-A-12. Since the 2-model (15, 17) 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 φ3.
