MFRAL Series for Plastic Use

3-element 0°/45°/90° stacked type for strain measurement in magnetic field

About the MFRAL Series for Plastic Use

MF series magnetic field strain gauge
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 dual element and 3-element rosette gauges of this series are usable in high temperature up to 200°C.
