Extensometers

There are contact and non-contact extensometers available to meet customers’ requirement.

For contact extensometers, there are basically two types of axial clip-on extensometers. The first type is long travel contact extensometers that we ideal for use when testing high-eongation materials. The second type is suitable for use with rigid, semi-rigid and ductile materials.

The video extensometer is the non-contact type extensometer.

There are contact and non-contact extensometers available to meet customers’ requirement.

For contact extensometers, there are basically two types of axial clip-on extensometers.

The first type is long travel contact extensometers that are ideal for use when testing high-elongation materials. It is specifically aimed at the plastic and rubber industries to provide accurate readings of strain and extension over a large extension range. The unit, incorporating two clamping arms and precision potentiometers, produces a DC voltage proportional to the distance between the arms. This generates accurate readings of percentage strain and allows additional parameters such as yield point and break points to be calculated when used with NEXYGENPlus software.

The second type is suitable for use with rigid, semi-rigid and ductile materials. The extensometer is supplied with a universal voltage external power supply unit, a loom and a connector to fit a range of machines, as well as a mounting stand.

The VE1 is a high precision video extensometer that uses a non-contacting optical measurement based on a digital camera and real time image processing to measure the longitudinal and transversal strain during tensile tests.

The VE1 extensometer offers high resolution measurement, simple preparations and an intuitive user interface. The video extensometer measures longitudinal strain between two applied lines at a rate of up to 100 Hz. The strain data is synchronised and transferred to NEXYGENPlus software (LD and LS test machines).

Strains from 20 um/m up to more than 1000% can be measured. System calibration provides measurements from a few millimeters to multiple meters.

The VE1 video extensometer saves images during the tensile test and can be used until sample break. It has a large application area and can test a wide range of materials including metals, rigid plastics, composites, ceramics, thick films etc. in both ambient and non-ambient temperature conditions.
