LINEAR DISPLACEMENT TRANSDUCER Russian patent published in 2009 - IPC G01B7/00 

FIELD: instrumentation.

SUBSTANCE: invention refers to instrumentation and can be used for linear displacement and vibrations control of various mechanical components and equipment at sites with harmful labor conditions, for example at nuclear power stations. Essence: transducer consists of two independent and moving components. The first component contains retractable rod spring-loaded relative to transducer body and semispherical contact tip and ferromagnetic core which are positioned coaxially with the rod. Ferromagnetic core is screwed into inner rod which is fixed in retractable rod body. Thermocouple is welded into intracavity of contact tip. The second component consists of non-magnetic bushing where differentially connected measurement windings are located. Free end of the bushing has a nut welded to it. Into nut screw is inturned which is connected by coupling with step motor shaft.

EFFECT: safety improvement due to possibility of remote calibration and adjusting, increase in accuracy, reliability.
