Displacement sensors


Philtec’s fiber optic displacement sensors make it possible to measure the distance, displacement and vibrations of a target without contact. They are of type D (axis of movement parallel to the probe) or RC (rotation, or translation) and are available in analog or digital versions controlled by computer. These sensors operate in the near field and offer a large measurement dynamic from a few nanometers to several tens of millimeters up to 1.5 MHz sampling.
