PLYMOUTH, MICHIGAN ---- The 15,000 PSI FIBER OPTIC PRESSURE SENSOR will be introduced at the Society of Automotive Engineers (SAE) International Congress and Exhibition at Cobo Center in Detroit, February 24 through February 27, 1997, Booth # 7508.

A 1/4 inch (~ 6mm) diameter diaphragm sensor is the newest addition to the Optrand family of fiber optic pressure sensors designed for engine optimization, diagnostics, monitoring, and control applications. The 15,000psi (~ 1,000 bar) sensor is offered in both FiberPSI™ and AutoPSI-S™ versions. Introductory sensor styles include 3/8-24 and M10x1.25 sensor packages with short or long shafts and a rotating mounting nut.

Due to its fiber optic construction the sensor is inherently non-electric, free from Electromagnetic Interference (EMI), and resistant to high temperature. Offered in miniature and robust packages it is particularly suitable for Performance Racing Industry, both for dynamometer and in-vehicle applications. In engines subject to extremely high levels of EMI, such as those utilizing magneto-based ignition systems, the Optrand sensor is the only transducer capable of measuring in-cylinder combustion pressures.

The 15,000psi sensor offers unique advantages for the development and OEM production of closed-loop controlled Diesel Direct Injectors (DDI). In combination with Optrand miniature combustion pressure sensors, the 15,000 psi fuel pressure sensor can be integrated into the "smart" fuel injector for simultaneous benefits of increased injector reliability and lower cost, as well as reduced engine emissions and improved fuel economy.

Optrand, Inc. is a Plymouth, Michigan based company involved in the research, development and manufacturing of fiber optic sensors for extreme environments. The company's products address pressure, temperature, air/fuel ratio monitoring and control needs in the combustion engine, electric utility, jet engine, and performance racing industries.
