Strain Gauge

Mechanical Strain Gauge was developed as a reliable and accurate way of taking strain measurements at different points on a structure using a single instrument.

With a discrimination of two microstrains (on the 200 mm gauge) and gauge lengths of 50 to 2000 mm the  strain gauge is ideal for use on many types of structure for strain

measurement and crack monitoring.

The Digital  Strain Gauge incorporates a digital indicator with a resolution of 0.001 mm, zero set, preset and output for SPC.

The indicator can be connected to a data processor for recording and analysis of results.

The indicator displays spindle movement digitally by means of a linear encloder and has a response speed of 1000 mm/sec, and is battery operated.

The strain gauge consists of an invar main beam with two conical locating points, one fixed and the other pivoting on a special knife edge.

The points locate in pre-drilled stainless steel discs which are attached to the structure with adhesive.

Movement of the pivoting point is measured by the strain gauge which is attached to a base plate on the invar beam. Design is such that thermal movement within the instrument

is negligible.

Strain gauges are supplied in a wooden case and come complete with an invar reference bar, for control measurements, and a setting out bar to

enable accurate positioning of locating discs.
