KDA-PA/KDB-PA Soil Pressure Gauge
Measuring soil pressure at construction site
Key features
- Minute displacement of pressue-sensitive area due to double diaphragm structure
- Can measue dynamic earth pressure, too
About the KDA-PA/KDB-PA Soil Pressure Gauge
The KDA-PA and KDB-PA are soil pressure gauges each 200 mm in outside diameter. They are widely used at construction sites. They are designed with a dual-diaphragm structure that can minimize the displacement of a sensing area and thereby can keep the stress distribution in soil undisturbed under pressure. The KDA-PA is used to measure the pressure in soil and to monitor the behavior of embankments. The KDB-PA is used to measure the pressure in earth retaining walls or the pressure on wall surfaces of structures.
