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.

This new pressure sensor provides the industry with better and more reliable pressure
measurements for existing applications, and with extended capabilities for
new applications requiring high operating temperature ranges.
With a temperature range of up to 450°C (842°F), the FOP-MH fi ber optic sensor
is ideal for aerospace and defense applications, and any other fi eld where extreme
temperature conditions can be found.
