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