FIELD: electric measurement technology; detection of interface between materials of different dielectric constants in construction, food and other industries. SUBSTANCE: device has sensing element 1 in the form of two electrodes, series-connected filter 3, threshold device 4, electronic switch 5, as well as voltage regulator 6 and ac voltage generator 2 whose output is connected with one of electrodes of sensing element 1 whose other electrode is connected to input of filter 3. Electrodes of sensing element 1 are metal half-cylinders with dielectric plate inbetween. EFFECT: enlarged functional capabilities; improved response to material interface level. |
