Abstract
A temperature sensor is formed from three initially unfired (or green) ceramic substrates. The first substrate has a temperature sensitive means printed on a first surface. Additionally first and second conducting elements are also printed thereon. The third substrate has a temperature sensitive means in the form of a resistor printed on a first surface. Additionally first and second conducting elements and are also printed thereon. The second substrate is provided with a conducting via in the form of a hole extending through the substrate, the hole being filled with conductive material. The via is adapted to be aligned with the ends of conducting elements. To construct the sensor the first surfaces of substrates are aligned with substrate such that via is aligned with conducting elements. The substrates are then pressed together. Subsequently the substrates are fired to provide the completed sensor.
