Products include extensometers for elongations up to 50% and gage lengths up to 2 inches, extensometers for high temperature or longer gage lengths, extensometers for high elongation, deflectometers and compressometers, and bolt extensometers, all of which use LVDT technology to measure the displacement. In addition to these technologies we can also supply strain gage based extensometers, powerful non contacting video extensometers, laser based non-contacting extensometers and encoder based automatic variable gauge length extensometers.
LVDT extensometers measure strain by means of knife edges which contact the sample, one of which is fixed in its position, and the other which is located on a moveable arm. This moveable arm is actually a pivoted arm, on one end is the knife edge and the other is attached to an armature that moves through an LVDT coil. Most of these extensometers can be adapted to your exact specimen holding needs by different options, but in their standard form hold flat or round specimens from 1/16” to 5/8” (1.6mm to 16mm).
