LF series Strain gauges for Wood and Gypsum

LF series strain gauges for wood and gypsum are foil gauges utilizing special plastic for the backing. The grid pattern is suited for measurement on materials having a low elastic modulus and reduces the stiffening effect of the strain gauge on the specimen. Gauges are self-temperature-compensated for 11×10-6/℃ materials.
A new series of strain gauges bearing the CE mark, GOBLET, has been added. This CE-compliant series of products is compliant with RoHS directives. These gauges exceed the capabilities of conventional strain gauges with lead-free soldering as well as a unique tab design. CE-compliant extension lead wires are also available.
