PROBE FOR MEASURING THERMAL AND HYDRAULIC PROPERTIES

摘要

A probe (10) comprises a base element (12), formed from an inflexible material and having one or more unitary rigid elongate prong members (18), heating and sensing elements (20) and (22) supported on the base element (12), and means for electrically energising at least the heating element (20). The heating element (20) is formed on the or one prong member (18) so that, when energised, the thermal energy output by the heating element (20) can be sensed by the sensing element (22) to determine at least the thermal conductivity of a substance in which the probe (10) is inserted.
