Pressure
cells consist of a pair of electron beam welded, stainless steel plates forming a capsule which is subsequently
filled with fluid under high vacuum . As pressure is applied to the capsule, the fluid pressure is transmitted via a thick
wall stainless steel to a vibrating wire transducer which transforms the applied pressure to a frequency output suitable for
data logging or remote reading.
Pressure cells are intended to measure applied pressure either in fill, at an interface between fill and rigid structure or as a means to measure changes in concrete stress.

NATM and Concrete Stress Cells
Vibrating wire Pressure cell for measuring changes in concrete stress, typically used in NATM shotcrete applications. Fitted with repressurising tube for initial thermal volume change compensation.

Jack Out Pressure Cell
Vibrating Wire Pressure cells to determine the earth pressure acting on diaphragm walls or barettes. The cell is initially installed in a reinforcing cage and then jacked out to contact the wall of the excavation.
