Absolute Position Sensor Linear

They are used whenever the motion of a machine element is to be controlled or monitored.
Absolute position sensor linear. Motion of the body can be rectilinear or curvilinear. Laser doppler vibrometer optical linear variable differential transformer lvdt photodiode array. Riftek s absolute linear encoder series includes two models. A position sensor may indicate absolute position location or relative position displacement in terms of linear travel rotational angle or three dimensional space.
Absolute linear position sensors absolute linear encoders are designed for measuring and checking displacements dimensions run outs surface profiles and deformations of engineered objects. Position sensors encoders provide an output signal proportional to the angle or speed of rotational or linear movement. Absolute linear position sensors such as magnetostrictive displacement transducers provide a unique output at a given position. Absolute position is a measurement of the precise distance between the sensor s measurement surface and the object.
Rf251for hard industrial environments and. Common types of position sensors include. Capacitive and eddy current sensors are primarily used as displacement sensors. 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.
Over time months and years sensor calibration shifts slightly. Typical applications are in industrial automation robotics machine tools office machines automotive etc. This shift is primarily a dc offset in the output of the sensor.
