A method of making a temperature sensing element from a composite sheet composed of two or more layers of materials having different coefficients of thermal expansion. To fabricate the element, a portion of one layer is masked, while a second portion of the layer is exposed and is removed by chemical or electrolytic action to provide an element in which one layer has a substantially greater surface area than the other layer. The element is shaped to the desired size and configuration and in use the element is mounted so that the peripheral edge is rigidly attached and sealed to a mounting support.
