Abstract
An electrical submersible pump has a tubular pump housing containing centrifugal pump stages and a rotatable shaft. A bearing mounts in the housing and has a shaft passage through which the shaft extends. A sensor hole extends through the housing and into the bearing. A temperature sensor is located within the sensor hole. The sensor hole has a closed end radially outward from the shaft passage. A sensor line leads from the temperature sensor to a sensing unit mounted at an upper or a lower end of the pump assembly.
