The Meggitt (Sensorex) SX41200 is a single axis closed-loop servo-inclinometer/ accelerometer,
designed to provide high reliability tilt or acceleration measurements within extreme environments,
and particularly those characterized by high shock and vibration inputs.
The highly rugged design of the SX41200 incorporates a galvanometric pendulum sensing element
with hydro-mechanical damping, combined with an optical position sensor, with voltage or current
output, proportional to the sine of the angle of tilt.
When the instrument is submitted to a certain angle alpha, the galvanometric 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.

Applications
 Industry :
-

Alignment of structures
(rolling mills,
alternators…)

-

Safety purpose
(cranes, offshore
platforms…)

-

Levelling (roads,
railway tracks…)

-

Angular measurements

 Defense :
-

Positioning of shooting
platforms, radar
antennas…

-

This current, proportional to the measured gravity, passes through an accuracy resistor and
provides the output voltage. An output amplifier gives low output impedance.

Detection of ship roll
and pitch
