BPC-A
For underground pore pressure measurement
Embedded in soil, BPC-A transducers measure underground pore pressures. A double-cased structure lets them perform without receiving any adverse effect from lateral pressures and makes them suitable for measurement where underground soil pressures change significantly. The cable length may be as desired.
?? Double-cased structure ensures measurement without receiving any effect of lateral pressure.
?? Flat filter (10??m mesh standard) is provided to prevent the sensing part from clogging.
?? Stainless steel case (including flat filter FB-10SUS)
