RC models are suitable for both single-axis measurements and measurements on objects that move past the sensor

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
  • Waver alignment
  • 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

RC sensors have a positive slope with increasing displacement. In contrast to the D models, they are monovalent with no near/far optics peak range and do not have to be calibrated to the target surface. 

These sensors are suitable for measuring applications with static, moving or rotating objects to be measured, e.g. B. discs and shafts, or for the measurement of parts during the process.

DC-20KHz is standard

DC-200KHz or higher is optional

DC-100 Hz provides the best resolution

Standard analog sensor units include:

Electronics with 0 to +5 VDC output

1 meter long fiber optic cable

Distance Sensors Reflection Compensated

Analog sensors are fast responding units ideal for relative motion measurements in dynamic applications with speeds up to 1 MHz.
