1. A device for determining the density of insulation, the device comprising:
a probe configured to be inserted into insulation such that the probe contacts the insulation;
a first actuator configured to cause the probe to oscillate within a first plane;
a first sensor configured to sense the oscillation of the probe within the first plane;
a second actuator configured to oscillate the probe in a second plane that is perpendicular to the first plane;
a second sensor configured to sense oscillation of the probe within the second plane, the configured to generate a signal that represents the displacement and/or velocity of the probe within the second plane with respect to time; and
a control system configured to cause the first actuator and the second actuator to oscillate the probe,
the first sensor and the second sensor each being configured to generate a signal that represents the density of insulation, and
the control system is configured to use the generated signals to determine the density of insulation.
