Twin axis servo-inclinometer SX41400


The Meggitt (Sensorex) SX41400 is a dual axis closed loop inclinometer/ accelerometer, offering angular tilt or acceleration measurements in two perpendicular axis.

Rugged, watertight IP 65 sealed housing and hydro-mechanical damping allow a very high shock and vibration resistance.

A galvanometer pendulum sensing element, combined with an optical position sensor, offers two outputs proportional to the sine of the angle of tilt.

When the instrument is submitted to a certain angle, the galvanometer pendulum tends to move in the direction of the inclination. Its position is detected and converted into a current which feeds back to the galvanometer in order to bring it back to its initial position.

This current passes through an accuracy resistor and provides the output voltage.

An output amplifier gives a low output impedance.
