Miniature
High-Temperature Pressure Sensor
with 1.7mm diameter
February 19, 1999
PLYMOUTH, MICHIGAN ---- A MINIATURE high-temperature
pressure sensor offered by Optrand, Inc. will be on
display at the Society of Automotive Engineers (SAE)
International Congress and Exhibition at Cobo Center in
Detroit, March 1 through March 4, 1999, Booth # 1184.
This 1.7mm in diameter sensor is the newest addition to
the Optrand family of fiber-optic dynamic-pressure
sensors for detecting pressure in combustion cylinders
and fuel injection systems. Thanks to its exceptionally
small size the sensor can fit into pressure sensing spark
plugs, glow plugs, or fuel injectors for non-invasive
measurement in engine testing and R&D, as well as
calibration and mapping. The sensor is offered initially
for 0-100 bar (1,500 psi) and 0-200 bar (3,000 psi)
pressure ranges in the AutoPSI-S version (with signal
conditioner rated for -40 to 65oC) and the AutoPSI-HT
version (with signal conditioner rated for -40 to 125oC).
Utilizing a robust construction based on a flexing metal
diaphragm, which does not involve any transfer pins or
other mechanical coupling mechanisms, the sensor offers
exceptional durability of up to 1 billion pressure
cycles. Its other features include resistance to high
temperatures (combustion or 300° C continuous) and
immunity to Electromagnetic Interference/Radio
Interference (EMI/RFI).
For Original Equipment Manufacturer (OEM) applications
the sensor specifically targets combustion cylinder
pressure detection in gasoline direct injection (GDI)
engines where its miniature size and high temperature
resistance enables integration with a fuel injector or a
spark plug/pencil coil for closed loop fueling and
ignition feedback control. Other automotive applications
include injection fuel pressure control and monitoring in
direct injection gasoline, diesel, and gas engines.
Non-automotive applications include steam generators,
nuclear plants, plastics injection molding, and process
industries where the sensor can replace popular
thermocouples of the same diameter.

manufacturer of fiber optic sensors targeting automotive
and industrial applications.
