Many pressure sensor applications in rugged environments such as aerospace, automotive, industrial, and even medical equipment present developers with conflicting requirements that lead to expensive compromises. These sensors are often used to measure pressure, level, and flow of harsh fluids such as gas, oil, refrigerant, or other caustic solvents that can damage the sensor element. Extended temperature requirements offer additional challenges, even beyond compensation for accurate pressure readings. Automotive and aerospace specifications are especially stringent, with operating temperature ranges as broad as 40 °C to +150 °C. And these rugged applications typically have high reliability and accuracy requirements, since component failure can lead to product recalls or safety risk. To respond, equipment manufacturers rely on expensive ongoing maintenance and component replacement to work around the sensor's inherent short lifespan.
