A thermal conductivity type pressure gauge comprises a gauge head ( 2 ) being rotatably mountable in a vessel whose environmental pressure is to be measured and an elongate electrical filament ( 6 ) mounted in the gauge head, the gauge head ( 2 ) having an inlet where through the electrical filament is exposed to the environmental pressure within the vessel and the filament ( 6 ) having directional component lengths in two orthogonal axes, one of the orthogonal axes X-X being parallel to the axis of rotation of the gauge head ( 2 ).
