Monitoring device for monitoring position of movable valve unit of hydrovalve, has sensors arranged in housing at distance to each other with respect to movement direction of valve unit for detecting detection characteristic of valve unit

摘要

The device (2) has sensors (12, 14, 16) i.e. inductive proximity switches, arranged at a valve unit (4) for detecting a detection characteristic of the valve unit, where the sensors are arranged in a housing i.e. control and/or spring housing, at a predetermined distance to each other with respect to a movement direction of the valve unit. The housing is arranged at a front flange of a valve housing, and a detector disk (46) is fastened to an end section of a pin, where the sensors comprise sensor holes that run in the housing in a radial direction. An independent claim is also included for a hydrovalve comprising a monitoring device.
