Abstract

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.
