These
are 200-mm outer diameter soil pressure gauges widely used at construction
sites.
They are designed with a dual-diaphragm structure that can minimize the
displacement of the sensing surface when pressure is applied, and thereby keep
the stress distribution in the soil undisturbed. KDA-PA and KDB-PA models are
available with differing cable exit directions, with KDA-PA used to measure
pressure in soil and monitor the behavior of embankments, and KDB-PA used to
measure pressure in earth-retaining walls and soil pressure on walls of
structures.
Protection ratings : IP 68 equivalent
Features
· Minute displacement of pressue-sensitive area due to double diaphragm structure
· Can measue dynamic earth pressure, too
