Request Information
The 1.7mm sensor package is a suitable OEM package for integration into almost any pressure measurement application. Available in the –S and –HT variants, this sensor is a prime candidate for sensing spark plugs, glow plugs, and fuel injectors for non-invasive pressure measurement in engine testing and R&D, as well as calibration and mapping. The sensor is available 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° C (or combustion) and is immune to all electric 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/ignition 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.
