Patent ID: 7061232

Claim:
A position transmitter, comprising at least one magnetoresistive sensor and an associated magnetic multipole wheel having a large number of uniformly arranged pole pairs ( 2 ), wherein the at least one sensor comprises first, second,third, and fourth magnetoresistive resistors that are electrically connected as a Wheatstone bridge with two half bridges, with a voltage UO being fed in one bridge diagonal and a sinusoidal or cosinusoidal signal being produced on the other diagonal, wherein a distance (d) between the first and second or third and fourth resistors located parallel to one another is selected with reference to a scanning direction of the multipole wheel, such that it is not equal to the wavelength of a pole pair, wherein a distance between the first and second resistors and between the third and fourth resistors is the same, a second sensor, the second sensor is electrically in the form of a Wheatstone bridge with two half bridges, and wherein the distance between the half bridges of the first sensor is d=λ/3 and the distance between the half bridges of the second sensor is d=2*λ/3.
