Video Extensometer is a contactless optical measurement system based on a digital camera and real time image processing. It measures the longitudinal and transverse strain between two applied lines with a rate of up to 4000 Hz. The strain data is transferred e.g. via an analogue signal or digital interface to the test machines for further processing or controlling.
ApplicationsMeasurement of material properties, true strain controlled tensile tests, fatigue tests, exploration of cracks, investigation of strain behavior on dynamic tensile tests, dynamic and high speed tests, vibration analysis, etc.
