Fibre Optic Sensors - Description

 

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
  • Detecting scratches
  • servo control
  • Coil deflection
  • speed measurement
  • Measurement of structural deformation
  • Recording the surface quality
  • Vibration measurement on the turbine blade
  • Measuring the vibration in the ultrasonic range
  • Control of the process in a vacuum
  • Valve characteristic measurement and valve lift measurement
  • Automatic parts inspection
  • Bearing / shaft dynamic measurement
  • Commutator profile
  • Computer hard disk mounting
  • deformation study
  • Distance to glass
  • Distance to paper
  • Distance to plastic
  • Dynamic expansion
  • Disk thickness
  • process control
  • Out of roundness
  • Shaft orbit
  • Detection for structural deformationg
  • Measuring the surface quality
  • Elongation and vibration of the turbine blade
  • ultrasonic vibration
  • Application in ultra-high vacuum
  • vibration analysis
  • Structure twist

The product range for optical sensors includes:

  • Reflection-based D-sensors for applications in which the measurement object moves along the sensor axis.
  • Reflection-compensated RC sensors for applications in which the target is rotated or moved out of the sensor area.
  • Vacuum sensors are ideal for wafer spacing and position measurements in vacuum. They represent a powerful low-cost alternative to laser interferometry.
  • Electronics with analog and digital output

All sensors can be manufactured according to customer specifications.

 

D-Sensors Specifications

 

For applications in which the measurement object moves along the sensor axis.
D sensors provide an output signal that is proportional to the distance and reflectance of the object surface. The output function provides two usable operating ranges: In near side operation, the highest resolution is achieved, while at far side the distances high sensitivity is available in a larger working range.

 

   

Areas of application for D sensors are, 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

  • deformation study
  • Distance to glass
  • Distance to paper
  • Distance to plastic
  • Dynamic expansion
  • Disk thickness

RC-Sensors Specifications

 

RC models (Reflectance Compensated) are used for translating and rotating targets, where the target reflectance is variable. The RC type sensor is a more general purpose optical sensor that can make accurate distance measurements to rotating or translating targets as well as measure part-to-part size variations in production parts.

   

Principle of Operation: These are retro-reflective optical devices. The sensors use bundled glass or quartz fibers to transmit light to and receive reflected light from target surfaces. The intensity of the reflected light is processed to provide the distance between the sensor tip and a target surface..

   

Areas of application for RC Sensors are, for example:
  • Automatic parts inspection
  • Bearing / shaft dynamic measurement
  • Commutator profile
  • Computer hard disk mounting
  • deformation study
  • Distance to glass
  • Distance to paper
  • Distance to plastic
  • Dynamic expansion
  • Disk thickness
