Combined Pressure and Temperature Sensors in Aerospace Applications

Combined pressure and temperature sensors have many applications in various industries, including aerospace. In aerospace applications, where precise pressure and temperature measurements are crucial for safe operation, combined pressure and temperature sensors are widely used. In this article, we will discuss the importance of combined pressure and temperature sensors in aerospace applications, their working principle, and some of the common aerospace applications of these sensors.

Importance in Aerospace Applications:

In aerospace applications, combined pressure and temperature sensors are used to monitor and control critical parameters, such as the temperature and pressure of the engine, fuel, and hydraulic systems. These sensors help ensure the safe and reliable operation of aircraft, spacecraft, and satellites.

Pressure and Temperature Sensors Working Principle:

Combined pressure and temperature sensors work on the principle of piezoresistivity, which is the ability of certain materials to change their resistance when subjected to pressure or temperature changes. The piezoresistive material used in these sensors is typically a thin film of silicon or other semiconductor material. The pressure-sensitive material is formed into a strain gauge, which is attached to a diaphragm that deflects when pressure is applied. The temperature-sensitive material is located adjacent to the strain gauge and experiences the same temperature as the gauge. When the temperature changes, the resistance of the temperature-sensitive material changes proportionally, and the change in resistance is measured by the sensor and converted into an electrical signal.
