• Up to 300°C for 8 hours
• Thermally insulates your downhole electronics
• External fast response temperature sensor
• Internal pressure measurement
• Can be expanded to measure flow and add a casing collar locator
A geothermal tool has a large Dewar flask housing that insulates the internal, temperature sensitive components. As well as the insulating housing, the tool assembly has a large internal heat sink assembly. The insulation, and the internal heat sink work together to prevent and absorb heat energy. This allows the internal electronics to stay below their critical operating temperatures.
The following graph illustrates the geothermal tools performance at different external temperatures.
