measurement technology. SUBSTANCE: device controlling level of dielectric loose material has low-voltage power supply source, signal electrode, common electrode, relay element and high-voltage low-capacity pulse converter. Signal electrode is mounted in vessel with the aid of bushing insulator at controlled level. Common electrode contacts wall of vessel with loose material. Input terminals of high-voltage pulse converter are connected to low-voltage power supply source and its output terminals are linked to common electrode and via relay element to signal electrode. EFFECT: expanded application field, raised functional reliability of device. 1 dwg |
