摘要
A measuring system for determining the distance (A) to a magnetic alternating field source (7), with a magnetic sensor arrangement (8), by means of which a characteristic magnetic alternating field signal of the magnetic alternating field source (7) can be recorded, and an evaluation device (12) connected with the magnetic sensor arrangement (8) and by means of which the characteristic magnetic alternating field signals of the magnetic alternating field source (7) recorded by the magnetic sensor arrangement (8) can be evaluated and converted into the distance (A) between the magnetic alternating field source (7) on the one hand and the magnetic sensor arrangement (8) on the other. In order to submit such a measuring system and also a corresponding method for measuring the respective distance, which also for disturbed environments offers the possibility of taking reliable and accurate distance measurements in the range from millimetres to a few hundred centimetres at minimal technical and constructional expense, it is proposed that the magnetic sensor arrangement (8) comprises at least two magnetic field sensors (9, 10) arranged at a fixed distance (B) relative to each other on an axis of movement (X) and in that the magnetic alternating field source (7) is movable along the same in respect of the magnetic sensor arrangement (8), and in that the characteristic magnetic alternating field signals recorded in the at least two magnetic field sensors (9,10) can be received in the evaluation device (12) and set into a relationship (ratio) to each other, and the ratio between the at least two characteristic magnetic alternating field signals can be converted into the distance (A) between the magnetic alternating field source (7) on the one hand and the magnetic sensor arrangement (8) on the other.
