Made in Japan
Manufacturer: Kyowa Electronic Instruments Co., Ltd.
Model: BEN-A-1MP

A pressure-sensing surface 70mm in diameter.
Vibration-resistant design for installation on driven materials
The BEN-A series soil pressure transducers are specially designed to endure vibrations. Thus, they are suitable for installation on driven materials such as sheet piles and steel pipe piles.

Features

●Dual diaphragm design, with the pressure medium sealed between the pressure-sensing surface and strain gagebonded diaphragm, enables transmission of minute displacement through enlargement.
●Vibration-resistant design for installation on driven materials
●Highly wear-resistant pressure sensing surface
