Device based on a static accelerometer and on a digital microcontroller able to read and to condition the sensor signals to compute a 0  - 360  angle and give a 4 - 20 mA current output.
Typically designed for mobile machine application. Compact design. Easy installation. Very strong solution, no mechanical moving part, able to tolerate high intensity mechanical shock.
Typical applications are on cranes, knuckle boom cranes, access platforms, motor ladders, excavators, concrete pumps, drilling machines, everywhere is requested reliability and vibrations resistance.
