Abstract
An automatic lubricator for lubricating an object is described, which comprises a housing with a coupling section configured to couple with a lubricant container containing a lubricant, wherein the lubricant container comprises a rotatable shaft with a piston to dispense the lubricant from an output of the lubricant container. The lubricator further comprises an electric motor configured to drive the rotatable shaft of the lubricant container during at least one lubrication action, such that at least a part of the lubricant is dispensable from the lubricant container during the at least one lubrication action, and a power supply configured to supply the electric motor with a supply current during the at least one lubrication action. The lubricator further comprises a control circuitry configured to acquire a current signal indicative of the supply current over time during at least a part of the at least one lubrication action, determine a periodicity of the acquired current signal, and determine, based on the determined periodicity, at least one lubrication parameter indicative of the at least one lubrication action.
