摘要：
Paper presents results of investigation on influence of external magnetic field on measuring characteristics of magnetoelastic sensor with ring-shaped core. The core of sensor was made of a high permeability amorphous alloy. External magnetic field up to 4 kA/m was generated by Helmholtz coils. Presented results confirm significant role of the demagnetization in analyze of influence of the external magnetic field on characteristics of the magnetoelastic sensors. Due to demagnetization even strong magnetic field has relatively small influence on the functional properties of the sensor.
