  • MF series: Magnetic field strain gauges

    The MF strain gauges have a sensing element material that exhibits low magnetoresistance for strain measurement in magnetic environment. The sensing elements consists of two identical grids with one grid folded back on another which makes the gauges less sensitive towards magnetic interference. The MF strain gauges also have a pre-attached twisted leadwire that further reduce the magnetic influence. They are usable for measuring at temperature up to 200oC.
