Fiberoptic Sensors for Non-contact Measurement of Linear Distance, Displacement and Vibration

Glass fibers with a light beam width of 25°, 30° and 66° are used to manufacture Philtec sensors.
The narrower beams give longer ranges. The standard cable length is 90 cm.

25° fibers can be used in continuous lengths up to 3 meters.

30° fibers can be used for continuous lengths up to 9 meters.

66° fibers can be used for continuous lengths of up to 15 meters.

All sensors can be manufactured according to customer specifications.

Fiber-optic sensors for distance measurement and vibration measurement work without contact and are a favorable alternative for measurements in production engineering. Typical applications are here, for example:

  • Motion detection of the actuators
  • Vibration in the ball bearing
  • Deflection of the membrane
  • Distance measurement in liquid
  • Dynamic inspection on the fuel injector
  • Penetration study and stroke study
  • Positioning of parts
  • Vibration investigation on the piezocrystal
  • Piston Position Detection (TDC)
  • piston travel
