A metal piece is provided with a body portion having a center passageway extending from one end thereof to a point short of the opposite end thereof, such body portion having two flat parallel sides lying parallel to the center axis of the passageway. A pair of resistance strain gages are bonded to each of the two flat sides above the passageway. One strain gage on each flat side is oriented to measure transverse strain and the other is oriented to measure axial strain. The four strain gages are connected to form a Wheatstone bridge, the transverse strain gages causing the bridge to provide an indication of fluid pressure within the passageway and the axial strain gages providing temperature compensation for the bridge.
