Abstract
A probe for a thermo-anemometer-type fluid flow rate sensor is disclosed. The probe comprises a tubular body member having a thermally conductive housing disposed within a fluid passageway and a detection module in the housing. The detection module includes a detection circuit and a heating circuit and is adapted to provide an output that varies in response to a change in temperature. The detection module is made from a ceramic substrate upon which the detection circuit and the heating circuit are deposited.
