MECHANICALLY CONTROLLED TUBE Russian patent published in 2000 - IPC

FIELD: mechanical and instrumentation engineering. SUBSTANCE: mechanically controlled tube designed for measuring and recording displacements and forces such as for tracing turbine shaft rotating in axial direction has case, gas absorber, plane- parallel electrodes (fixed heater cathode and two anodes), and rod passed through diaphragm installed in case; one of anodes is fixed inside case in insulators and other one is moving anode overhung in insulators on rod end. Cathode and anodes are provided with leads. Novelty is introduction of permanent magnet mounted on loose end of rod. Such novelty provides for using device to measure axial displacements of rotating shaft by contactless method. EFFECT: enlarged functional capabilities. 2 dwg
