Understanding Dual Axis Inclinometers: Background and Applications
While they may be small, the role of rotary encoders in spacecraft is vital, demanding a balance between performance, reliability, and the unforgiving environment of space. From NASA’s Robonaut II to automated material handling systems on the International Space Station, Everight has worked with engineers to put rotary encoders into ‘the final frontier.’
SSI hardware is fairly simple. Just use any RS-422 transceiver to generate the differential signals from/to the microcontroller port pins. Keep reading to learn about the different implementations of SSI hardware.
For applications where sudden movements, shocks, and vibrations are likely to be encountered, it is important to have sensors with fast response and a clean signal output. POSITAL’s dynamic inclinometers combine two measurement principles using two different MEMS sensors: a 3D acceleration sensor and a 3D gyroscope.
Why Holistic Encoders are More Accurate
All absolute rotary encoders have a rotor which is attached to the rotating shaft and a stator which is attached to the housing holding the shaft. The interaction of these two components produces a measure of the shafts rotational angle. The most important parameters of absolute rotary sensors are resolution, accuracy and tolerance to misalignment of the rotational axes.
