BS-8FT
This transducer is designed to measure strain in the inside or on the surface of thin concrete wall or on the surface of steel such as a wide flange beam.
The BS-8FT strain transducer is designed to measure strain in the inside or on the surface of a thin concrete wall or on the surface of steel such as a wide-flange beam. A temperature measuring function enables it to simultaneously measure strain and temperature. Since the compact design measures only 80 mm in length, embedment applications are limited to concrete with comparatively small aggregates.
?? Self-temperature compensation type designed with a linear expansion coefficient approximated
to that of concrete
?? Wide application range including measurement of strain on an earth retaining strut,
steel sheet-pile and tunnel support
?? Usable for long-term measurement in place of a directly bonded strain gage
