Position Sensors Ready For Saltwater Apps

The company's LVDT-based linear position sensors can handle high-pressure and seawater environments, making them suitable for deployment in sub-sea measurement systems to monitor the structural integrity of offshore platforms and pipelines. They are designed for use in either pressure-balanced, oil-filled containers, or directly in seawater. Typical applications include monitoring structural movement for a long-term finite element analysis of pipelines, derricks, and moorings. For measurements in seawater depths down to 7,500' with an external pressure of approximately 3,800 psi and minimum service life requirements of 20 years, the LVDTs employ 316SS and Inconel 625 for pressure and corrosion resistance. To minimize the number of pressure-sealed connections and I/Os, a 4 mA to 20 mA two-wire, loop-powered I/O is available. For more details, call MACRO SENSORS, Pennsauken, NJ. (856) 662-8000.
