Profile: Optrand, Inc. specializes in the development and manufacturing of static and dynamic pressure sensors for continuous monitoring and control, as well as testing & diagnostic applications. Our 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. Sensors are designed for continuous operation in harsh conditions of high temperature up to 350°C, high electro-magnetic and radio frequency interference fields, and chemically volatile & explosive environments. Our products are suitable for a wide range of applications such as combustion pressure measurements in gasoline, diesel, natural gas, and racing engines. Our products are also used in the applications such as marine, hydraulics, fuel injection, turbochargers, oil and gas exploration, die casting, nuclear and avionics.
