Sensor Fusion

 

The CURTAIN systems of Hammer-IMS accommodate single or multiple M-Ray sensors and, if desired, combined with other sensor types:

  • M-Ray sensor, for thickness or basis-weight measurement
  • 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 allows different types of sensors to be installed in your CURTAIN system in order to run different measurements simultaneously. Concretely, Hammer-IMS offers both thickness & basis-weight measurements in a single non-contact measuring solution. We see that measuring material thicknesses and basis-weight at the same time is emerging nonwovens quality control.

The combined thickness/weight measuring solution of Hammer-IMS perfectly responds to this market evolution. While the non-nuclear M-Ray sensor is measuring nonwoven basis-weight, the 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.
