Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 105 words
A transducer sensor head including a first cylindrical ferromagnetic core having a first coil associated therewith, characterized in that there is provided a second cylindrical ferromagnetic core 24 similar to said first core 23 and having a second coil associated therewith, said first and second coilsbeing electrically interconnected in series and being so wound on their respective cores 23, 24 that the magnetic fields which they induce are cumulative, and means 16 mounting the first and second cores 23, 24 spaced apart with their axes co-extensive, the cores 23, 24 being spaced apart by a distance of the order of the diameter of the cores.
Claim 2
Dependent Claim 105 words
A transducer sensor head including a first cylindrical ferromagnetic core having a first coil associated therewith, characterized in that there is provided a second cylindrical ferromagnetic core 24 similar to said first core 23 and having a second coil associated therewith, said first and second coilsbeing electrically interconnected in series and being so wound on their respective cores 23, 24 that the magnetic fields which they induce are cumulative, and means 16 mounting the first and second cores 23, 24 spaced apart with their axes co-extensive, the cores 23, 24 being spaced apart by a distance of the order of the diameter of the cores.
Claim 3
Dependent Claim 48 words
A transducer characterized by comprising a sensor head as claimed in Claim 1 and a rotatable vane 12, the vane 12 being rotatable about an axis parallel to the axes of the cores 23, 24, and the periphery of the vane 12 extending between the cores 23, 24.
