LIGHTWEIGHT,DUST PROOF,
ROBUST CONSTRUCTION WITH
DIGITAL DISPLAY
The CONVEX-Si is a digital tape extensometer which quickly and accurately measures changes in distance between two reference points in any orientation.
The CONVEX-Si digital tape extensometer basically consists of a steel survey tape with punched holes, loaded on a reel fixed to the body of the instrument.
There is a digital LCD display to accurately read the relative change between two reference points. By turning the rotary protection drum, it is easy to get quick access to the digital display function buttons through the opening provided for this purpose.
Two hooks are provided, one at the movable end of the tape and the other on the reel frame.
Tensioning of the tape to a predetermined load is easily done by rotating a large knurled collar until two reference lines are precisely aligned. Visual alignment is optimized by the use of two superimposed magnifying lenses. The CONVEX-Si can be easily handled by only one person.
For an actual measurement, the CONVEX-Si is stretched between two reference points consisting of two stainless steel eyebolts fixed on their respective anchor.
A verification frame can be used to regularly check the repeatability of the instrument.
