About the PFLC Series Straingauge for Concrete Material

PF series polyester wire strain gauge
These are foil strain gauges utilizing a polyester resin backing which is the same as the P series. The gauge length is available in 3 ranges of 10, 20 and 30mm, so it is suited mainly to strain measurement on concrete or mortar. The backing is transparent and the installation is easy.

Dedicated leadwire recommended for PF series strain gauges
We supply various leadwires dedicated to strain gauges so as to meet our customers’ requirements.
For CE marked strain gauges, only the leadwires using lead-free solder are available.
