FBG Earth Load Cell

FBG Earth Load Cell is a new type of optical earth load gauge developed by using high-quality constant elasticity alloy as the load transmitter, and then utilizing the inherent strain sensing characteristics of fiber grating. The Earth Load Cell is suitable for measuring soil stress in building foundations such as earth-rock dams, breakwaters, revetments, quay walls, high-rise buildings, pipeline foundations, bridge piers, retaining walls, tunnels, subways, airports, highways, railways, and anti-seepage wall structures, as well as the measurement of freezing force in glacier frozen soil. Earth Load Cell has the advantages of good stability, suitable for long-term monitoring, etc., and comes with self-temperature compensation.
