MF series Magnetic field strain gauge

mf_list These gauges are designed for strain measurement in magnetic field. The gauges have a sensing element material which exhibits low magnetoresistance. In addition, the sensing element consists of two identical grids with one grid folded back on another. These construction makes the strain gauges less sensitive to the influence of the alternating field. The gauges have a twisted leadwire pre-attached which is also effective to avoid the influence of the alternating field. The 2-element and 3-element rosette gauges of this series are usable in high temperature up to 200°C.
