fluid within the motor 34 and alleviates mechanical loading on pressure seals within the esp system 20 an optional gauge 37 is shown attached to the pressure equalizer 36 in an example embodiment the gauge 37 is coupled with the umbilical 45 for measuring conditions downhole and providing data signals representing the measured signals through the umbilical 45 to a monitoring system not shown embodiments exist wherein the umbilical 45 connects to windings not shown in the motor 34 so the signals travel through the windings and a power cable energizing the motor 34 optionally a dedicated line can connect between the umbilical 45 and monitoring system examples of measured conditions include temperature pressure and fluid properties the gauge 37 may be attached to an end of the pressure equalizer 36 distal the end of attachment to the motor 34 or another upwardly disposed pressure equalizer the motor 34 can generate heat to an already heated area thus an advantage of setting the gauge 37 away from the motor 34 is an easing of environmental conditions experienced by the gauge 37 potentially prolonging the useful life of the gauge 37 referring now to fig2 provided is a side partial sectional view of a portion of the esp 20 of fig1 that illustrates in more detail an embodiment of the.
