Abstract:
Voltage-generating magnetic sensors using new square-loop Fe-Cr-Ni magnetic alloy wires are described. Typical magnetic properties of the sensor wire are Br ∼15 kG, Br/Bs ∼0.99, and Hc ∼2–30 Oe. These alloys are corrosion resistant, easy to manufacture into desired wire shape and sensor geometry, and are of low material and processing cost. One exemplary sensor consists of an Fe-20%Cr-4%Ni alloy wire of 0.1–0.5 mm in diameter, 3.7 cm in length, and a sense coil of 1000–2000 turns wound around the alloy wire. With an external ac drive field of 20–200 Oe at various frequencies, voltage pulses with a peak amplitude in excess of 30 V are generated. This sensor may be used as a proximity/displacement sensor, current sensor, rotation/frequency sensor, and other triggering, switching, and security devices.
