About the BTM Series for Strain in Bolt Measurement
BTM/BTMC series bolt strain gauge
These gauges are used for measurement of tensile strain of bolt. They are simply inserted into pre-drilled hole in the bolt with exclusive adhesives. This method is recommendable when an ordinary strain gauges can not be mounted on the bolt surface. Accurate tensile force measurement is possible by calibrating the bolt after installing the bolt gauges.
The BTM bolt gauges use heat-curing A-2 adhesive for installation, which provides better long-term stability
