Relative pressure sensor FOP-MH

opticalanaloghigh-temperature

The FOP-MH is a fi ber optic pressure sensor designed mainly for applications where extreme temperature conditions can be found such as aerospace and defense. It is also a useful tool for general industrial applications in harsh and hazardous environments. Designed to operate in extreme temperature conditions, where standard sensors fail, the FOP-MH pressure sensor offers immunity to EMI/RFI, a small size, reliable measurements under harsh conditions, high accuracy, resistance to corrosive environments, and high endurance to extreme temperatures. Research engineers in aerospace, defense, and different industrial areas may now improve process and product technology by monitoring the performance of specifi c properties over time that will provide accurate information on changes in pressure during the operation, the manufacturing process or throughout the lifetime of a product. The use of the FOP-MH pressure sensor allows a complete pressure analysis in the most challenging environments, especially those characterized by high temperatures. The FOP-MH fi ber optic pressure sensor is based on proven Fabry-Perot interferometer technology. The sensor’s unique design is based on defl ection measurement of a silicon diaphragm, as opposed to more conventional stress measurement techniques. Pressure creates a variation in the length of the Fabry-Perot cavity and our fi ber optic signal conditioners can consistently measure the cavity length with high accuracy under all adverse conditions of temperature, EMI, humidity and vibration. The mechanical robustness is assured by the epoxy-free, all glass construction.
