7. An apparatus, comprising:
an electrical submersible pump assembly comprising:
a motor, having a housing and a shaft, the shaft having a shaft axis, a first end and a second end;
a pump, mechanically coupled to the first end; and
a sensor system comprising:
a rotational transmitter assembly comprising:
a cylindrical body having an axial length, a first end configured to fixedly attach to the shaft of the motor, a second end having an end face, a circumferential face positioned on an outer surface of an outer diameter of the cylindrical body and a pocket positioned within the circumferential face;
