<p>A temperature sensor 300 is formed from three initially unaired (or green) ceramic substrates 301, 302, 303. The first substrate 301 has a temperature sensitive means 304 printed on a first surface. Additionally first and second conducting elements 307 and 309 are also printed thereon. The third substrate 303 has a temperature sensitive means 305 in the form of a resistor printed on a first surface. Additionally first and second conducting elements 308 and 310 are also printed thereon. The second substrate 302 is provided with a conducting via 306 in the form of a hole extending through the substrate 302, the hole being filled with conductive material. The via 306 is adapted to be aligned with the ends of conducting elements 309 and 310. To construct the sensor 300 the first surfaces of substrates 301, 303 are aligned with substrate 302 such that via 306 is aligned with conducting elements 309, 310. The substrates 301, 302, 303 are then pressed together. Subsequently the substrates 301, 302, 303 are fired to provide the completed sensor 300.</p> |
