BEE-A
Soil Pressure Transducer

Summary

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.

Features

●Applied pressure causes minimal diaphragm displacement thanks to a dual diaphragm design.
●Highly accurate displacement ratio of the pressure-sensing surface to its diameter is less than 1/100,000.
●Can measure dynamic soil pressure caused by earthquake, etc.
