BEM-A
Soil Pressure Transducer

BEM-A

Summary

The BEM-A series is underground soil pressure transducers with a pressure-sensing surface 80 mm in diameter. Strainless steel construction.

Features

●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.
●Stainless steel construction
