Transducer for determining thread tensile force on textile machine, has sensor element with coil, plunger coil with annular body that has immersion opening for sensor element

摘要

The transducer has a sensor element (1) with a coil (2), a plunger coil with an annular body that has an immersion opening for the sensor element. The annular body carries a coil arrangement. An evaluation circuit (14) is provided for dispensing an output signal (A) dependent from the axial position of the sensor element relative to the annular body. An alternating current exciter (10) energizes an alternating current in the coil of the sensor element.
