Optrand exhibited at the SAE2008 World Congress

14 May, 2007:

Optrand's president, Dr. Marek Wlodarczyk, hosted a presentation titled "Measuring Cylinder Pressure for Controlling Diesel Engines" during the Sensors Expo Pre-Conference Program #3

Optrand introduced its new Pressure Measuring Glow Plug, the PSIglow, at the Society of Automotive Engineers (SAE) International Congress and Exhibition at Cobo Center in Detroit, April 16 through April 19, 2007. This newest generation device integrates Optrand's 1.7mm-diameter fiber optic-based pressure sensor with a fully functional ceramic heater-based glow plug allowing cylinder pressure monitoring of diesel engines without head modification or loss of glow plug functionality

18 April, 2005:

Optrand sensors are now rated to 350 Deg C (662 Deg F) continuous housing operating temperature!

1 Nov, 2003:

Optrand's miniature pressure sensor integrated in a glow plug adapter is featured in a PhD dissertation: "Conception and test of a cylinder pressure based engine management for passenger car diesel engines" presented by Jens Jeschke at the University of Magdeburg. The sensor is integral to the cylinder pressure based management system that claims across the board improvements in emissions, particulate matter, and "increases robustness of emissions with respect to engine part tolerances and environmental conditions" in passenger diesel engines. A link to the thesis and English abstract is available HERE

The sealed-gauge sensors utilize one or multiple optical fibers positioned in front of a flexing metal diaphragm. The intensity of the reflected light is proportional to the pressure induced deflections of the diaphragm. The patented sensor head, diaphragm and the auto-referencing technique guarantee long-term reliability required in OEM monitoring and control systems.  

The long-life (up to 1 billion cycles or 3 years), low-cost sensors are offered in various packages as small as 1.7 mm in diameter and pressure ranges from 0-100 psi (7 bar) to 0-30,000 psi (2000 bar). These sensors are designed for continuous operation in harsh conditions of high temperature up to 350°C (e.g., combustion), high Electro-Magnetic and Radio Frequency Interference fields (EMI/RFI), and chemically volatile and explosive environments. Sensors require neither water nor air-cooling.  

Miniature size, dielectric nature and resistance to high temperature make Optrand sensors ideal for integration with Spark Plugs, Direct Fuel-Injectors or Glow Plugs for non-intrusive real-time cylinder pressure measurements. 

Optrand products are suitable for a wide range of applications such as:
 Combustion pressure measurements in gasoline, diesel, natural gas, and racing engines
 Plastic industry (extrusion, injection and compression molding)
 Compressor pressure monitoring
 Marine
 Hydraulics
 Fuel injection
 Turbochargers
 Oil and gas exploration (down hole instrumentation)
 Die casting
 Nuclear
 Avionics
 Defense
