Versatile strain gauge range added to Variohm portfolio

Standard strain gauges are encapsulated in Constantan foil with phenolic-acetal backing and, with self-temperature compensation, are available in a variety of patterns and materials for research and industrial stress measurement. Versions with paper-based acetal backings are also supplied for use in composite materials or cement structures.

Special purpose strain gauges include Karma foil gauges with glass-fibre reinforced polyamide backing which have excellent heat-resistance and excellent insulation characteristics. Within the special purpose range, waterproof and submersible versions are available for use up to 50bar (5MPa). Special purpose strain gauges also suit applications where high elongation, uneven plastic deformation, high altitude and other challenging environmental factors need to be resolved.

Zemic strain gauges for high precision transducers are available in four model versions with Constantan and Karma foil encapsulation to suit up to Class 0.02 transducers. With self-temperature and creep compensation these gauges excel where high elongation, excellent heat resistance and wide temperature range are prerequisites. In particular, versions are available to specifically suit electronic weighing instruments.

Variohm also supply terminal tabs with a choice of polyimide or glass fibre reinforced backings for use across the Zemic strain gauge range.
