Downhole sensor system with thru shaft

IRZ TMS downhole sensor system with thru shaft is designed for wells with one motor and two pumps.

The system ensures the control and transmission of real-time parameters during oil production including the following:

  • pump intake pressure
  • motor oil temperature
  • reservoir fluid temperature
  • motor vibration level
  • motor and power cable insulation resistance

IRZ TMS is used as a part of ESP system. Parameters controlled by IRZ TMS enable the pump control system to:

  • protect the pump
  • optimize pump operation
  • automatically control the level of fluid
  • collect data for downhole production tests

Advantages

  • the downhole sensor system has an overvoltage protection up to 3000 V
  • data is transferred to an external device via RS232 or RS485 interface using the IRZ TMS ELEKTON, BORETS communications protocols
  • short downhole data scanning interval — max 20

IRZ TMS delivery set includes:

  • TMS-E5-01 or ASPT ground acquisition unit
  • BP-117 PRD downhole unit
