摘要： Systems and methods are presented for cancelling noise from sensed magnetostriction-based strain measurements. A drive signal corresponds to a drive coil, and a sensed signal corresponds to a sensed coil. The drive signal is used to at least partially eliminate noise similar to the drive signal from the sensed signal to generate an output signal.

摘要： A system includes a sensor configured to detect an electrical leakage current associated with an operation of an industrial machine. The sensor includes a core and a first winding encircling a first portion of the core. The first winding includes a first number of turns. The first winding is configured to obtain a set of electrical current measurements associated with the operation of the industrial machine. The sensor includes a second winding encircling a second portion of the core. The second winding includes a second number of turns. The second winding is configured to obtain the set of electrical current measurements associated with the operation of the industrial machine. The first winding and the second winding are each configured to generate respective outputs based on the set of electrical current measurements. The respective outputs are configured to be used to reduce the occurrence of a distortion of the set of electrical current measurements based on a temperature of the core.

The driving pole includes a driving coil that may receive a driving current and may emit a magnetic flux portion through a rotary structure. The sensor head also includes a sensing pole including a sensing coil that may receive the magnetic flux portion and may transmit a signal based at least in part on the received magnetic flux portion. The received magnetic flux portion is based at least in part on a force on the rotary structure. The sensor head also includes a temperature sensor disposed on the sensor head. The temperature sensor may measure a temperature of the rotary structure.

摘要： Sensor assemblies, electrical penetrator assemblies and associated methods are provided for monitoring operational characteristics of subsea rotating devices such as subsea motors and pumps. Pressure-compensated proximity sensors configured to withstand subsea pressures are disposed adjacent a subsea rotating shaft for directly monitoring a position of the rotating shaft during dynamic operation thereof. A sensor tip assembly includes a sensor cap and a sensing element therein configured to produce a signal indicative of a distance between the sensor cap and the rotating shaft. A substantially incompressible fluid is disposed within a fluid reservoir within a sensor housing, and fluidly communicates with the sensor cap such that at least a portion of an internal pressure within the sensor housing is applied to interior portions of the sensor cap. The sensor housing is configured such that the internal pressure increases in response to an increase in an external pressure of the sensor housing.

摘要： Sensor assemblies and methods of assembling and using the sensor assemblies are provided for monitoring operational characteristics of subsea rotating devices such as subsea motors and pumps. Pressure-compensated proximity sensor tip assemblies configured to withstand subsea pressures are mounted adjacent a subsea rotating shaft for directly monitoring a position of the rotating shaft during dynamic operation thereof. An end of a sensor housing opposite a sensor tip assembly is mounted to a wall of the device housing. The sensor housing defines a fluid reservoir containing a substantially incompressible fluid therein that is in fluid communication with the interior portions of the proximity sensor tip assembly. A length of the sensor housing is adjusted to accommodate a distance between the wall of the device housing and the rotating shaft.
