Meggitt Sensing Systems introduced its Sensorex SX41200 and SX41400 series, two families of gravity referenced closed-loop servo inclinometers/accelerometers. The sensors are 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. The lines’ 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 IP65 sealed aluminum housings and the units are powered by a single, unregulated voltage supply and feature a bidirectional output. Additional options include a ±0.02 percent non-linearity error specification (excluding ±90° range), special bandwidth, zero offset (unipolar output) and special range and output signals. In addition, all Sensorex SX41200 and SX41400 series models conform to both European EMC and railway testing standards.
