Limit transducer electronic - Inductive contact / electronic contact - DESCRIPTION It is the task of the limit transducer to close or open power circuits via a contact arm that is moved by the current value indicator. Inductance is the phenomenon where a fluctuating current, which by definition has a magnetic component, induces an electromotive force (emf) in a target object. The change in resistance is measured by the ac or dc measuring devices.The resistive transducer is used for measuring the physical quantities like temperature, displacement, vibration etc. They are. When the target moves closer to the coil due to the displacement, the air gap becomes less causing the reluctance of the magnetic field to reduce and thus the coil inductance to increase.
