Embodiment Construction

[0014] figure 1 An exemplary power system 100 including a machine 102 is shown. In the exemplary embodiment, machine 102 may be, but is not limited to only, a wind turbine, a hydroelectric turbine, a gas turbine, or a compressor. Alternatively, machine 102 may be any other machine used in a powertrain. In the exemplary embodiment, machine 102 rotates drive shaft 104 , which is coupled to load 106 , such as a generator.

[0015] In the exemplary embodiment, drive shaft 104 is at least partially supported by one or more bearings (not shown) housed within machine 102 and / or load 106 . Alternatively or additionally, the bearings may be housed within a separate support structure 108 , such as a gearbox, or any other structure or component that enables powertrain 100 to function as described herein.

[0016] In the exemplary embodiment, powertrain system 100 includes at least one sensor assembly 110 that measures and / or monitors machine 102 , drive shaft 104 , load 106 of powertr...

Abstract

The invention relates to a sensor assembly and microwave emitter for use in the sensor assembly. A microwave probe for use in a microwave sensor assembly includes an emitter body and an emitter coupled to the emitter body. The emitter includes a first portion, a second portion, and a connecting portion coupling the first portion to the second portion. The first portion and the second portion generate an electromagnetic field when at least one microwave signal is received, and a loading is induced to the emitter when an object is positioned within the electromagnetic field.

Description

technical field [0001] The present application relates generally to power systems and, more particularly, to sensor assemblies and microwave emitters for use in sensor assemblies. Background technique [0002] Machines are known to exhibit vibration or other abnormal behavior during operation. One or more sensors may be used to measure and / or monitor this behavior, as well as determine, for example, the amount of vibration exhibited in the machine drive shaft, the rotational speed of the machine drive shaft, and / or any other behavior of the machine or motor in operation characteristic. Typically, such sensors are coupled to a machine monitoring system that includes multiple monitors. The monitoring system receives signals from one or more sensors, performs at least one processing step on the signals, and transmits the modified signals to a diagnostic platform that displays metrics to a user. [0003] At least some known machines use eddy current sensors to measure vibrati...
