Harsh environment closed loop servo inclinometers/accelerometers

August 09, 2012 // By Julien Happich
The Sensorex SX41200 and SX41400 series from Meggitt Sensing System are two families of rugged, gravity referenced closed-loop servo inclinometers/accelerometers designed for use in harsh environments.

Available in 12 individual models per series, with angular measurement ranges from ±3° to ±90°, and choices of single axis (SX41200) and twin axis (SX41400) versions, their highly rugged design incorporates a galvanometric pendulum sensing element with hydromechanical damping, combined with an optical position sensor, with 4-20 mA or ±5 VDC (±5%) output, proportional to sine of the angle of tilt. Inertial sensing elements are contained within rugged, watertight IP65 sealed aluminum housings. They are powered by a single, unregulated voltage supply and feature a bidirectional output. Additional options, available upon customer request, include a ±0.02% non-linearity error specification (excluding ±90° range), special bandwidth, zero offset (unipolar output) and special range and output signals. All Sensorex SX41200 and SX41400 series models conform to both European EMC and railway testing standards.
