The temperature sensor of the submersible pump

Downhole sensor of ESP is a measuring device of downhole signal,which uses multiple sensors and signal processing circuit fixed in a sealed unit,and which is connected with the bottom end of the submersible motor.Downhole sensor monitor the downhole pressure,temperature,pump outlet pressure,vibration unit,unit insulation single and other single or multiple parameters.Downhole sensor will transmit data via a three-phase submersible cable to the ground,to achieve the protection of ESP unit and the monitoring of oil well conditions.Powerlift has two series of downhole sensors,two parameters and six parameters.Downhole sensor technology specifications are as follows:
