1. An Electrical Submersible Pump (ESP) system, comprising:
a submersible pump defining a central bore extending longitudinally therethrough, the submersible pump being operable to pump in an uphole direction a wellbore fluid received in the central bore thereof;
an intake coupled to the submersible pump and defining a central bore extending longitudinally therethrough and aligned with the central bore of the submersible pump to define a longitudinal passageway through the ESP system through which an intervention tool may be passed;
an intake filter removably positioned within the central bore of the intake and removable through the central bore of the submersible pump; and
a downhole sensor axially interposing the submersible pump and the intake, wherein the downhole sensor includes a central bore extending therethrough that is aligned with the central bores of the submersible pump and the intake.
