Abstract
The present invention relates, in general, to pressure sensors capable of operating at high temperatures. The present invention further relates to a high temperature pressure sensor with an improved gage factor. The present invention still further provides a pressure sensor with a smaller sized diaphragm, which is capable of reading higher pressures. The present invention also provides a method and sensor for detecting strain using shape memory alloys.
