<p>The unit has a transducer unit (2), a source (3) energizing the transducer unit and an amplifier (4) attached to the transducer unit. The transducer unit contains a transducer bridge connection with two parallely switched bridge arms (5,6). Each bridge arm has a magnetic field transducer (7,8) and an arm unit (9,10) switched in sequence. The amplifier is attached to two pick-up nodes (11,12), one of which is provided between the magnetic field transducer and the arm unit of each bridge arm. The first magnetic field transducer of each bridge arm is a tunnel magneto-resistor, which consists of multiple tunnel elements electrically switched in sequence.</p> |
