BS-15CT
Surface-mounting Type Strain Transducer

bs-15ct

Summary

For measurement of strain on steel and concrete surfaces.
The BS-15CT surface mounting type strain transducer is developed especially for measurement of strain on steel and concrete surfaces. A temperature measuring function enables simultaneous measurement of strain and temperature. Installed on a pile or steel sheet pile, the rugged design endures vibration initiated by driving the pile.

Features

●Self-temperature compensation type with linear expansion coefficient approximated to that of concrete (11μm/m/℃)
●Large capacity (±2000μm/m), shock- and vibrationresistance, and integrated mounting legs
●Applicable for steel pipe piles, steel pipe laggings, steel sheet piles and hydraulic iron pipes in power stations
