Absolute position sensor linear.

How far the body has moved from its reference or initial position is sensed by the position sensors and often the output is given as a fed back to the control system which takes the appropriate action. Laser doppler vibrometer optical linear variable differential transformer lvdt photodiode array. Continuing the example assume a linear transducer with 100 of total travel over which it produces a 0 to 10 vdc output. Common types of position sensors include.

This shift is primarily a dc offset in the output of the sensor. For example a linear position sensor with analog voltage 0 10 vdc output produces a constant repeatable output at any position within its total travel. Capacitive and eddy current sensors are primarily used as displacement sensors. Over time months and years sensor calibration shifts slightly.

A position sensor may indicate absolute position location or relative position displacement in terms of linear travel rotational angle or three dimensional space. Riftek s absolute linear encoder series includes two models. Absolute linear position sensors absolute linear encoders are designed for measuring and checking displacements dimensions run outs surface profiles and deformations of engineered objects. Accordingly position sensors are called linear position sensors or angular position sensors.

Motion of the body can be rectilinear or curvilinear. Absolute linear position sensors such as magnetostrictive displacement transducers provide a unique output at a given position. Position sensors encoders provide an output signal proportional to the angle or speed of rotational or linear movement.
