To improve uniformity of heating of a sensor element carried on a plate-like carrier, in which electrodes are applied to one or both of the major surfaces of a carrier plate to form the sensor element, the heater element is constructed in form of a zig-zag or meander track surrounding the flat electrodes and positioned adjacent the edge portion of the carrier plate, so that, in a direction transverse to the major plane of the carrier plate, the heater element will be positioned closely adjacent the electrode, and prevent the formation of temperature gradients which might lead to fissures or breaks in the elements of the sensor construction.
