Abstract: A monitoring process for a grease lubricated rotating system having a processing unit linked to a measurement system for measuring the water content within lubrication grease. A learning period is performed that establishes upper and lower thresholds based on current measurements. If at least a first number of measurements out a second number of last measurements are above the upper threshold then if such is the case, emitting a first event. If at least the first number of measurements out the second number of last measurements are below the lower threshold, then if such is the case, emitting a second event, if at least a first event has been emitted, if such is the case emitting an alarm function of the at least first event.

Abstract: A system with at least one control unit and a bearing arrangement that includes at least one sensor unit for measuring a quantity. The system is configured to find out with the help of the at least one sensor unit first values of the quantity in a first time span for a first set of instants of time. The system is further configured to infer second values of the quantity for a second set of instants of time from third values measured via the at least one sensor unit in a second time span. The first set of instants of time is different from the second set of instants of time.

Abstract: A system for synchronous control of a plurality of sensors for sensing at least one characteristic such as temperature, vibration or movement, of at least one bearing, is provided. The system includes the plurality of sensors, which are in association with at least one machine. The system also includes a management device communicatively coupled to the plurality of sensors. The system provides, to the plurality of sensors, a measurement command to instruct the plurality of sensors to perform synchronous measurements of the at least one machine. The system receives, from the plurality of sensors, a plurality of measurement values corresponding to the synchronous measurements.

Abstract: A condition monitoring system that determines a presence of change of water content in grease. The system provides a sensor electrode that is placed in the space where the grease is located. The electrode is suitably a plate with a surface area creating a capacitance C. This in combination with a resistor R, creates an RC circuit. The system senses the RC circuit. The dielectric constant of the monitored grease varies in dependence of the water content of the grease. A change of the dielectric constant will change RC, that is then sensed by the system. An analysis of a change of RC will determine if there is a presence of a change of the level of water content in the monitored grease.

Abstract: The present invention relates to a measurement device for a rotating system, the measurement device providing a first sensor arranged in the vicinity of a shaft of the rotating system, the first sensor being configured to generate a signal relating to a rotation of the shaft, and a control unit connected to the first sensor. The control unit is further configured to form a first parameter based on the signal from the first sensor, determine a current time reference, form a data package having the first parameter and a time stamp relating to the current time reference, and distribute the data package to at least one monitoring device over a network connected to the control unit. The present invention also relates to a monitoring system having the measurement device and a corresponding method for monitoring a condition of a rotating system.
