OPTRAND Inc specializes in the development and manufacturing of static and dynamic Pressure Sensors for continuous monitoring and control, as well as testing and diagnostic applications. The firmâs sealed-gauge sensor technology utilizes 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 the long-term reliability that is required in OEM monitoring and control systems. The long-life low-cost sensors offered by the firm are offered in packages as small as 1.7 mm in diameter, with pressures ranging from 0-100 psi to 0-30,000 psi. These sensors are designed for continuous operation in harsh conditions of high temperature up to 350°C, high Electro-Magnetic and Radio Frequency Interference fields (EMI/RFI), and chemically volatile and explosive environments. Sensors require neither water nor air-cooling. 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; and defense industries
