Abstract
To provide for rapid temperature response to changes in temperature of an air flow past the sensing end portion of a resistance sensing track (13) on a ceramic substrate (12), the resistance sensing track is applied in a meander of a predetermined length, which is spaced from contact terminal points (14) to the meander by at least the longitudinal extent (19) of the meander; two covering layers (20, 21) are provided, one (20) being thin and covering the meander and adjacent connecting tracks (15, 16), and the other (21) being thick and sturdy and retaining the plate (12) in position in a housing (1, 2), overlapping the first covering (20), but being spaced therefrom by at least half the longitudinal extent (19) of the meander.
