PROBE Russian patent published in 2001 - IPC

FIELD: measurement technology, conducting of various measurements. SUBSTANCE: given probe is made of conductors in insulation shells and measurement lug put into space of case. Case comes in the form of spring. Adjacent turns of spring contact one another when probe is in free state. Adapter carrying first end of cone is installed between case and measurement lug. Second end of case can be placed on bushing. Adapter and bushing have longitudinal axial holes. Diameter of wire of spring and length of conductor are determined by relationship with due account of longitudinal axial force, force of initial compression of spring, its structural characteristics and mechanical properties. Dimensions of case are chosen by relationship taking into account number of conductors and physical properties of material of probe. EFFECT: increased functional reliability and serviceability of probe used in bent, extended and narrow conduits. 1 cl, 4 dwg
