Abstract
A pressure sensor with the goal of enhanced reliability and built-in redundancy is developed using the possibilities offered by highly sensitive and high temperature stable thin films. The sensors show promising results with potential application for high temperature applications and incorporate a modular approach using an ultra-thin glass based strain gauge with redundant Wheatstone bridges joined to a monolithic stainless steel membrane by glass soldering.
