Foil Type Strain Gauge
FLM / WFLM Series Metal Backing Strain Gauge
These strain gauges have thin stainless steel backings which prevent the penetration of moisture from the reverse sides. This construction is aimed for successful strain measurement on concrete surface. The WFLM gauges have moisture proofing over-coating and integral leadwire in addition to the stainless steel backing. It is intended for long term measurement or measurement on underwater-curing conctrete.

MF Series Magnetic Field Strain Gauge
These non-inductive strain gauges are designed for strain measurement in magnetic fields. Two strain gauge elements are overlapped to cancel out electromagnetic induced noise occurring in the gauge, and the twisted lead wire also similarly works to cancel out induced noise. Their structure makes them less sensitive to induced noise from alternating fields.

QMF Series Magnetic Field Strain Gauge
These are non-inductive strain gauges suited to the measurement in magnetic field. The sensing element of the gauge consists of two identical grids with one grid folded back on another. This construction makes to cancel the electromagnetic noise induced in the grids. The twisted leadwire of the gauge is also effective to cancel the noise induced in the leadwire in the same way. Accordingly, this strain gauge is less sensitive to the influence of noise induced in changing magnetic field. It utilizes polyimide resin for the backing and is applicable to the measurement in high temperature.
