Abstract
This invention relates generally to a thermal conductivity probe. In one embodiment, a thermal conductivity probe includes, but is not limited to, at least one heating element, at least one thermal insulator, and at least one thermistor thermally isolated from the at least one heating element by the at least one thermal insulator.
Claims21
A probe comprising:
- a cone penetration head configured to obtain cone penetration testing (CPT) data;
- at least one heating element;
- a plurality of temperature sensors, the plurality of temperature sensors being thermally insulated within the probe from the at least one heating element;
- and
- at least one processor configured to determine thermal conductivity of material around the probe based on a mean time to rise to a specified temperature gain over ambient as measured using the plurality of temperature sensors.
2 more elements
A probe attachment device comprising:
- at least one heating element;
- a plurality of temperature sensors, the plurality of temperature sensors being thermally insulated within the probe attachment device from the at least one heating element;
- and
- at least one processor configured to determine thermal conductivity of material around the probe attachment device based on a mean time to rise to a specified temperature gain over ambient as measured using the plurality of temperature sensors,
- wherein the probe attachment device is configured to removably couple to a cone penetration head configured to obtain cone penetration testing (CPT) data.
2 more elements
A device, the device comprising:
- a cone penetration head including one of more sensors;
- at least one heating element;
- a plurality of temperature sensors, the plurality of temperature sensors being thermally insulated within the device from the at least one heating element;
- and
- at least one processor configured to determine thermal conductivity of material around the probe based on a mean time to return to ambient temperature from a gain over the ambient temperature as measured using the plurality of temperature sensors.
