A pressure-sensing surface 160mm in diameter,used most popularly in measuring fields.
The BEE-A and BEF-A series are soil pressure transducers with an outer diameter of 200 mm which are used most popularly in measuring fields. The BEE-A series for underground soil pressure measurement is embedded in a core zone of a rockfill dam or ordinary banking. The BEE-A series can also measure soil pressure of 3 or 4 face objects. The BEF-A series can be used for soil pressure measurement of a continuous underground earth retaining wall.| Performance |
