CLIP-ON EXTENSOMETER – MECHANICAL EXTENSOMETER FOR MATERIAL TESTING – BMT-CME
The clip on extensometer is a mechanical strain measurement device designed for accurate deformation measurement during material testing applications. BESMAK Clip-on Mechanical Extensometers are suitable for round specimens up to 25 mm in diameter and flat specimens up to 31 mm in width and 12 mm in thickness. Designed to meet the accuracy requirements of ASTM E83 Class B-1, these extensometers provide reliable measurement performance for laboratory and material testing applications.
Different initial gauge lengths are available to meet various testing requirements.
What Is a Clip On Extensometer?
A clip on extensometer is attached directly to a test specimen to measure changes in length during mechanical testing. By monitoring specimen deformation over a defined gauge length, the extensometer provides measurement data that can be used during the evaluation of material behavior. Clip-on extensometers are commonly used as part of material testing systems where accurate deformation measurement is required.
