Magnetic detecting apparatus with novel means for positioning sensor assembly in a housing |
摘要 |
A magnetic locator in which flux-gate sensors are mounted in longitudinal notches at the ends of a tubular support to form an assembly which is inserted into a tubular housing, the sensors being press-fitted into the notches and the tubular support being provided with spaced bushings of material which is compressed when inserted into the housing. A stiff hairpin excitation conductor extends through the sensors and through the tubular support, being preassembled with one of the sensors and being connected to a circuit chassis for positioning the sensor assembly in the housing. A simplified electrical circuit is employed which produces a beat frequency signal when a magnetic object is located and which avoids the need for a voltage to frequency converter.
