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
