Abstract
A submersible well pump has a system for monitoring the pressure and temperature in the vicinity of the motor. The system includes a downhole assembly in the well that has a transmitter for generating a signal and superimposing the signal onto the power cable. Transducers in the downhole assembly sense physical parameters such as pressure and temperature and provide electrical responses corresponding to the physical parameters. The transducers are connected to a modulator which modulates the signal provided by the transmitter according to the electrical response of the transducers. The modulated carrier signal is converted at the surface into a readout signal proportional to the physical parameters.
