FIELD: electricity.
SUBSTANCE: invention is related to a sensing device to be mounted at the electric machine shaft with a recording unit to record current values of the electric machine bearing. The sensing device to be mounted at the electric machine shaft comprises a recording unit intended to record current values of the electric machine bearing. Further the sensing device comprises an energy converter, which is mounted with the recording unit in a replaceable module, in order to convert mechanical energy of the shaft to electric energy for the recording unit.
EFFECT: designing small-size sensing device with independent power supply.
