Miniature High Temperature Pressure Sensor
| The 1.7mm sensor package is the ideal OEM package for integration into almost any pressure measurement application. Available in the -S and -HT variants, this dynamic sensor is a prime candidate for sensing spark plugs, glow plugs, and fuel injectors for noninvasive pressure measurement in engine testing and R&D, as well as calibration and mapping. The sensor is available in 0-100 Bar (0-1,500 psi) and 0-200 Bar (0-3,000 psi) pressure ranges. Utilizing a robust construction based on a flexing metal diaphragm the sensor offers exceptional durability of up to 150 Million cycles without the use of transfer pins or other mechanical coupling mechanisms. The sensor offers a maximum continuous operating temperature of up to 300 degrees C (or combustion) and is immune to all electrical magnetic and radio interference. For OEM applications the sensor is specifically targeted for combustion cylinder pressure measurement in gasoline direct injection (GDI) engines where its miniature size and high resistance to temperature enables integration into fuel injector or spark plug based closed loop fuel/ingnition control systems. Other automotive applications include control systems. Other automotive applications include fuel pressure control and monitoring in direct injection engines. In non-combustion applications, the sensor can replace thermocouples of the same diameter making it ideal for a drop-in pressure sensing solution. Like all AutoPSI sensors, a small, permanently attached signal conditioner, including all the optics and electronics, eliminates the need for a separate, costly interface. |
