Best Practice for the maX System

The special features of an X- ray backscatter sensor allow a couple of new application fields for the maX system, which can not be covered by a conventional measurement.

Easy and cost efficient set up of the single sided travelling line

  • In a production line, this system is easy to install. Directly after your process of interest, as e.g. the coater, the scattering unit, the impregnating device. These positions in the line are also first choice when using the measured values for controlling the process.
  • No measurement gap, no problems with available space, no dirt problem.
  • Measurements possible, where a supporting means is needed, as e.g. a conveyor belt, a calander, a chiller roll.

High distance tolerance

A specific developed device, an adaptation unit for scattered radiation, makes it possible to employ the backscattersensor at different distances to the materials to be measured. Alignment of the sensor is facilitated considerably.

High energy X-ray spectrum

The tunable X-ray source creates a high level radiation spectrum which is convenient for the backscatter process. This leads to the following results:

  • Low influence of the chemical composition of the material to be measured. By physical reasons, measurement systems using the transmission of X-rays do not show this favourable property.

  • Possibility to measure high material weights due to the low absorption of the high energy X-radiation. Textured material as e.g. nets, can be measured simply and without calibration correction.
