Revolation rate measurement arrangement - has rotatably driven magnet carrier in pot-shaped housing with magnetic ring, magnetic field sensor, and drive arrangement

摘要

The revolution rate measurement arrangement has a pot-shaped housing (1) contg. a rotatably driven magnet carrier (3) with a magnetic ring concentric to the rotation axis with peripherally distributed magnetic poles passing by a fixed magnetic field sensor. A drive journal (10) protruding from the housing is connected to a drive shaft (23) rotatably mounted in a casing attached to the housing. The magnet carrier is supported on the housing floor (8) via a ball bearing (13) and radially guided in the housing. It is acted upon by the end of the drive shaft in the direction of the housing floor. USE/ADVANTAGE - The revolution rate measurement arrangement contains a few simple parts and is easily assembled.
