Noncontacting displacement measuring system having an electric field shield

摘要

A noncontacting displacement measuring system therefor a sensor (2) with a housing (11), at least one coil (1) accommodated in the sensor housing (11) and an embedding substance (13) for anchoring the coil (1), and further therefor an electronic supply/evaluation unit, is designed such that the influence of fluids and solids with a high dielectric constant on the measured values is large eliminated. To this end, a shield (15) is provided on the measuring side (8) of the sensor (2) , which is at least largely impervious to electric field lines (9) emanating from the coil (1), but largely permeable to electromagnetic field lines emanating from the coil (1).
