BS-15CT
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.
?? Self-temperature compensation type with linear expansion coefficient approximated
to that of concrete (11??m/m/??C)
?? Large capacity (??2000??m/m), high-shock and vibration-resistance,
and integrated mounting legs
?? Applicable for steel pipe piles, steel pipe laggings, steel sheet piles and hydraulic iron pipes
in power stations
