Beschreibung
Zusammenfassung:	instrumentation engineering. SUBSTANCE: process of manufacture of Bourdon springs is specifically related to manufacture of restoring sensitive elements which are primary converters employed to measure pressure of fluid media from units to tens of MPa. Tube before deformation during process is filled with fine-grained filling agent, for example, sodium bicarbonate. Tube with filling agent is rolled prior to heating. Spring is bent by revolving around roller. Filling agent is removed by chemical way, for instance, by boiling in solution of acetic acid. Bending of deformed tube around roller can be conducted by slow or fast revolving with application of force from outside. EFFECT: possibility of manufacture of Bourdon springs to measure pressure from one to tens of MPa with effective relation of strength, sensitivity and dimensions. 2 cl, 8 dwg
