Use Non-Intrusive Pressure Sensors:
The Challenge
Pressure measurement in pipelines and pressure vessels is a common practice for process control. Tracking pressure fluctuations and maximum pressure levels is essential for structural safety and operational efficiency. Unfortunately, most conventional pressure gages require an opening into the vessel or pipeline so that replacement of the sensor during operations is not possible. Also, since most pressure gages are electrical-based devices, they can pose a hazard when employed in flammable environments.
Is there a pressure sensing system that can be applied to the exterior of a pipe or vessel that is non-intrusive, requiring no drilling of holes or mechanical attachments? Is this system non-electrical and reliable? Can the sensors be applied to any accessible area where direct pressure measurements are required? Can these sensors operate at elevated temperature?
The Solution
FOX-TEK offers fiber optic sensor systems that measure pipe or pressure vessel pressures with high accuracy. The sensors are ideal for operation in flammable environments or in close proximity to electrical equipment because they are passive, non-electrical and immune to electromagnetic interference (EMI). They operate continuously at temperatures as high as 300°C. FT sensors are available in a variety of configurations, and because of their flexibility, are easily bonded to structures of complex curvature. Remote, continuous monitoring or periodic on-site measuring systems are options available to the user with FOX-TEK FT sensor monitors.
