Strain gauge clip-on extensometer

A strain gauge is an electrical resistor in the form of a series of reverse loops attached to an isolating foil at right angles to the strain measurement direction If the strain gauge is stretched in the direction of measurement, its electrical resistance increases. One or more sensors are attached to a mechanical arrangement. The specimen extension is transmitted via sensor arms to the mechanical portion(s) fitted with strain gauges, causing a defined deformation of the strain gauges.

  • Single-sided strain gauge system (clip-on extensometer)
  • Double-sided strain gauge system (clip-on extensometer)
  • Analog clip-on extensometer with extension piece
  • Biaxial strain gauge clip-on extensometer
  • ProLine strain gauge clip-on extensometer

Advantages of Zwick strain gauge clip-on extensometers

  • Zwick strain gauge clip-on extensometers feature excellent linearity, with correspondingly reliable test results.
  • Gauge lengths are adjustable from 10 to 100 mm, allowing flexible use for different specimen thicknesses.
  • Lightweight, miniaturized construction, well-suited to shorter specimens.
  • High resolutions of strain gauge clip-on extensometers enable measurement of very small deformations.
  • Temperature-resistant measurement systems for use from -70 °C to + 200 °C.
  • Strain gauge clip-on extensometers for two-sided measurement of specimen deformation, enabling exact determination of Young's modulus and engineering elastic limit.
  • Variable measurement options are possible on extensometers with 2 separate measurement systems; individual signals or mean-value signal can be displayed.
