BEM-A
A pressure-sensing surface 80mm in diameter.The stainless steel design enables marine applications.
The BEM-A series is underground soil pressure transducers with a pressure-sensing surface 80 mm in diameter. The strainless steel design enables marine applications.
?? 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
