Magnetic field strain gauge

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.
