Kyowa BER-A-500KP15S BER-A-15S Wall-surface Soil Pressure Transducer
Made in Japan
Manufacturer: Kyowa Electronic Instruments Co., Ltd.
Model: BER-A-500KP15S
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.
