DEFINITION

Classification: 324/247

Nonparallel plural magnetic sensors:

(under subclass 244) Subject matter wherein the apparatus to sense the magnetic field includes several magnetic sensors positioned angularly with respect to each other so that an axis of another sensor will intersect the other axis and the apparatus to indicate is connected to the several sensors to note the combined sensing of the tested magnetic field.

SEE OR SEARCH THIS CLASS, SUBCLASS:

227, for plural magnetic tests each having a magnetic field sensor.

228, for magnetic tests to subject material to a magnetic field.

242, particularly for material flaw testing apparatus using plural magnetic coil sensors.

243, for material tests using plural magnetic coil sensors to examine material.
