BED-A Small-sized Soil Pressure Transducer
Summary
A pressure-sensing surface 23mm in diameter. Suitable for measurement fo soil pressure distribution in short-term or model experiment The BEC-A and BED-A series are small-sized soil pressure transducers having an outer diameter of 30 mm and a pressure-sensing surface diameter of 23 mm. They are used for measurement of soil pressure distribution in short-term or model experiments.
