Sensor Fusion

Marveloc-CHARIOT systems accommodate a single sensor of any type. Marveloc-CURTAIN systems accommodate a single sensor or multiple sensors possibly combining various sensor types of Hammer-IMS or third parties:

  • M-Ray sensor (electro-magnetic), for thickness or basis-weight measurement of non-metallic materials
  • L-Ray sensor (laser), for thickness measurement of non-metallic sheets or films
  • U-Ray sensor (ultrasound), for thickness measurement of (coated) steel battery films
  • C-Ray sensor (capacitive) for thickness measurement of extruded thin plastics films
  • Edge-Vision machine-vision camera system, for dealing with various accept/reject problems, and identify anomaly levels in plastic film and sheet products, but also for nonwovens and coated textiles.
  • Eddy Current sensor, for measuring the distance from the M-Ray sensor to a metal base plate mounted underneath the material to be measured
  • Laser time of flight (TOF) or triangulation sensor, for hybrid thickness measurement or detection purposes
  • Laser curtain sensor, for surface roughness measurement
  • Other sensors

Supporting multiple sensor types

Single solution running multiple measurements simultaneously
Combining thickness & basis-weight measurements

Sensor fusion supports a vast choice of sensors and allows different types of sensors to be installed in your Marveloc-CURTAIN system in order to execute different measurements simultaneously. Concretely, Hammer-IMS offers sensor technologies for thickness, basis-weight and other measurements in a single non-contact measuring solution. We see that simultaneously measuring material thickness and basis-weight is emerging nonwovens quality control.

The combined thickness/weight measuring solution of Hammer-IMS perfectly responds to this market evolution. In a typical setup, a non-nuclear M-Ray sensor measures nonwoven basis-weight while a laser sensor continually tracks the material thickness. In addition, the laser sensor continuously identifies the edge of the moving nonwoven produce using enhanced-precision material edge detection. For optimal operation, the laser sensor requires sufficient material reflectivity.

Thin or thick materials measured with equal high precision

Another reason to add a laser sensor is obtaining the same high precision regardless when gauging thin or thick materials inline. Sensor fusion creates an optimal tradeoff between precision and measurement range in any Hammer-IMS thickness of basis-weight measuring solution.

There are many sensor types that can be combined in Hammer-IMS measuring systems, ranging from multiple laser types to Eddy Current sensors. Hammer-IMS has the hardware and software expertise to integrate various sensor types into its gauging machines. Contact Hammer-IMS to discuss your specific measuring application.
