TECHFIND - SENSORS
High Temperature Pressure Sensor
Researchers in Germany have developed a sensor that uses a new technology which makes them robust enough to continue operating normally at temperatures up to 250 degrees Celsius (482 degree Fahrenheit). The technology is designed for applications such as oil and gas exploration. In those applications, as the drill bit burrows deeper into the earth, working its way through rock, dozens of sensors monitor pressure and evaluate porosity. Because of the extreme conditions they face, the sensors are required to withstand high temperatures and pressures as well as shocks and vibrations as they send data to the surface to help geologists with tasks such as searching for oil deposits. On average, pressure sensors can only withstand temperatures of between 80 and 125 degrees Celsius, but at great depths the temperature is often significantly higher. The researchers chose silicon oxide to enable the chip to function properly at extremely high temperatures. There is a broad range of potential applications, with engineers hoping to use the high-temperature pressure sensors not only in the petrochemical environment, but also in automobile engines and geothermal applications.
