Foil Type Strain Gauge
LF Series Low Elastic Strain Gauge
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.

PFLW / PLW Series Low Elastic Strain Gauge
This gauge has a thin metal backing for long term measurement on woods, not affected by moisture contained in wood. The gauge is bonded with PS adhesive.
These gauges are specially designed for long term measurement on wood. They have a metal foil lined on the back of the PFL or PL strain gauges. The metal foil is effective to protect the strain gauges from an influence of moisture in the wood.
These gauges should be bonded with PS adhesive to make the best of their performance.
