Non Contact Displacement Sensors

OPTOCROWN™

The Marposs range of components for measurement applications includes a state of the art fibre optics sensor for contactless measurements.

The possibility of including Optocrown in Marposs Network Systems, provides contactless applications for delicate materials (glass or plastic) as well as mixed applications with different sensors, based on the requirements. 

BENEFITS
  • contactless measurement of parts
  • same diameter of Marposs RedCrown and DigiCrown contact sensors
  • can be included in DigiCrown modular systems for complex applications with up to 62 sensors
  • compatible with any Marposs display and statistical processing devices
  • it compensates for changes in light and reflectance of the material being measured
  • greater resistance due to no friction
  • up to 12 material calibrations can be stored
DESCRIPTION

OptoCrown™ is an optical sensor based on light reflection technology designed for contactless linear measurements. The sensor transmits a beam of light towards the part, through a bundle of fibre optics and receives the light from the part being measured through two separate bundles of fibre optics connected to two receivers. The distance between the sensor and part surface is determined by the intensity of the light reflected.

After being calibrated correctly the sensor can measure any type of material. Marposs can provide pre-calibrated sensors on the customer's materials, but the user can perform further calibrations autonomously. Thanks to the particular configuration of the fibre optics, the sensor is not affected by changes in the reflectance of the surface being measured.
