Absolute Position Sensor Linear

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.

Absolute position sensor linear.

Motion of the body can be rectilinear or curvilinear. Rf251for hard industrial environments and. Typical applications are in industrial automation robotics machine tools office machines automotive etc. Common types of position sensors include.

Accordingly position sensors are called linear position sensors or angular position sensors. Over time months and years sensor calibration shifts slightly. Absolute linear position sensors absolute linear encoders are designed for measuring and checking displacements dimensions run outs surface profiles and deformations of engineered objects. Continuing the example assume a linear transducer with 100 of total travel over which it produces a 0 to 10 vdc output.

Absolute position is a measurement of the precise distance between the sensor s measurement surface and the object. They are used whenever the motion of a machine element is to be controlled or monitored. Absolute linear position sensors such as magnetostrictive displacement transducers provide a unique output at a given position. 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.

A position sensor may indicate absolute position location or relative position displacement in terms of linear travel rotational angle or three dimensional space. This shift is primarily a dc offset in the output of the sensor. Capacitive and eddy current sensors are primarily used as displacement sensors.
