1.75" Geothermal PTF

Application

The 1.75” Geothermal Pressure Temperature Flow Gauge has an external fast response temperature sensor that is exposed to the wellbore fluid and an internal pressure piezo sensor that senses wellbore pressure. It is compatible with the 5” or 7” Fullbore Spinner as well as the 1.688” and 2.125” Continuous Spinner.

The temperature sensitive downhole electronics are thermally insulated inside a vacuum flask with a heat sink to reduce the rate of temperature rise within the flask. This allows the 1.75” Geothermal PTS tool to operate in extreme temperature applications; up to 300°C for 8 hours.
