Downhole Measuring System Triol ТМ01

Downhole Measuring System Triol ТМ01–18

Downhole Measuring System Triol TM01-18 is a high-temperature, reliable and profitable solution for systems working with hot fluids up to 175°C (347°F), where it’s necessary to collect, process, display and transfer actual parameters of the well and submersible equipment, with a pressure in the equipment suspension zone up to 40 MPa (5800psi)

  • pump discharge pressure;
  • pump discharge temperature;
  • submersible motor oil temperature or the temperature of the motor stator winding;
  • ESM vibration acceleration in the X, Y and Z axis;
  • insulation resistance in the circuit “Step-up transformer – submersible cable – ESM”
