Series ES291 transducers have a built-in monocrystalline silicium MEMS sensor for measuring inclination (with absolute vertical reference) as well as acceleration on X and Y axis.

MEMS sensors can measure both static and dynamic accelerations therefore they can as well as be used to measure inclinations that are typically static accelerations.

MEMS sensor measure acceleration and tilt by means of a differential capacitor whose parts move when a difference of acceleration and tilt is applied.

MEMS sensors are extremely rugged and can withstand hi shocks and vibrations with also the advantage of being miniaturized and with a good price to performance ratio.

Series ES291 allows to measure, accurately and with high resolution, accelerations and inclinations on X and Y axis, with absolute vertical reference.

When X and Y measuring axis are parallel to horizon, then MEMS sensor has the highest sensitivity to inclination because the working function is sinusoidal: Pitch (degrees)= sin (acceleration/1g).

When X and Y measuring axis are orthogonal to the horizon, then MEMS sensor has the lowest sensitivity to inclination because the working function is co sinusoidal: Roll (degrees)= cosine (acceleration/1g).

Applications:

Attitude control on industrial machinery, on industrial vehicles (agriculture machines, forest and timber machines, grading machines, caterpillars, drilling machines, concrete machines etc.), on boats, civil engineering applications (on dams, bridges, masonry walls, historical buildings, etc.), geotechnical applications, on antenna, inertial platforms etc.
