Abstract: Technologies are described for devices to monitor a machine. The devices may comprise a battery pack module including a battery pack housing and a sensor module including a sensor module housing and a circuit board. The circuit board may include a substrate, a vibration sensor, a temperature sensor, a motor flux sensor, an ultrasonic sensor, and a processor. The vibration sensor may produce a vibration signal relating to vibration of the machine. The temperature sensor may produce a temperature signal relating to a temperature detected. The motor flux sensor may produce a motor flux signal relating to an amount of motor flux emitted by the machine. The ultrasonic sensor may produce an ultrasonic signal relating to ultrasonic waves reflected back from the machine. The processor may be in communication with the vibration sensor, the temperature sensor, the motor flux sensor, and the ultrasonic sensor.

Abstract: Technologies are generally described for automatic sensor orientation detection in monitoring systems for rotating equipment such as pumps. To detect operational abnormalities or faults sensors such as vibration sensors may be placed on rotating equipment and their outputs used for diagnostic and corrective action purposes. An orientation (and/or location) of the vibration sensor may shift over time, or the sensor may be placed in the wrong orientation to begin with. According to some examples, one or more sensors or an inertial measurement unit (IMU) integrated with the vibration sensor or attached to it provide orientation parameters, which are used to determine an actual orientation of the vibration sensor and adjust diagnostic detection based on the actual orientation of the vibration sensor.

Abstract: Technologies are generally described for a vibration band alarm configuration tool to facilitate efficient and reliable setting configuration by displaying data and analyses pertaining to the data produced by a vibration transducer attached to a rotating machine and thereby reduces needed knowledge of machinery and vibration analysis. Various parameters and data sets may be calculated from the time domain waveform and displayed with collected data to simplify the recognition of features that represent system components and anomalies pertinent to the health of the rotating machine such as a pump assembly. Manually manipulatable controls on a graphic user interface may allow a user to set alarm bands and thresholds. Suggestions based on physical and/or statistical models, as well as, machine-specific historic data may be presented as well.

Abstract: Technologies are described for rigid mounting connectors to connect a monitoring device to a piece of equipment. The rigid mounting connectors may comprise abase and a column. The column may be tubular in shape and include a bolt opening configured to receive a threaded end of a bolt. The base may extend axially from and be attached to outside walls of the column. A length of the column may be perpendicular to the base and the column may be at a center of the base. The base may include cylinders positioned on a circle concentric to a center of the bolt opening. Each screw channel may be configured to receive a screw to fasten at least one printed circuit board assembly to a top side of the base. The base may include footings which may protrude out from a bottom side of each cylinder.

Abstract: A system and method employing wear debris sensors to monitor the operation of a lubricated mechanical system such as a gearbox (e.g., in a wind turbine), a transmission or an engine in order to control operation of the gearbox in order to reduce damage and/or extend the useful life of the gearbox.

Abstract: A sensor for measuring multiple properties of a fluid, such as oil, including level, temperature, water contamination, and dielectric where the sensing elements include two or more interdigitated electrodes, a capacitive relative humidity sensor, and a temperature sensing element.
