Features of the X-ray- Backscatter Sensor of the maX Measurement System

Compared to conventional systems for basis weight measurement (beta- or X-ray transmission), maX features three important items:

Single sided measurement

In contrast to conventional measurement systems, the emitter and receiver modules of the maX X-ray sensor are both mounted in one single housing. The measurement signal for the determination of the basis weight value, is created by the reflected (scattered) part of the X-radiation directed towards the fabric. So, there is no narrow gap between emitter and receiver part of the sensor, where a fabric has to pass through. The material can be scanned from one single side only.

High distance tolerance

The sensor of maX features a high distance tolerance. Variations of the distance between sensor and fabric, like they show up in web flutter, do not affect the values measured. This is a specific development that has been patented. Above all, this feature makes a single sided measurement reliable and simple.

No radioactivity

The radiation of the maX sensor is created by an X-ray tube, that can be shut down. There is no radioactive material inside the sensor. This facilitates radiation protection considerably.

Compared to conventional measurement systems, these three basic features are characteristic for the X-ray backscatter sensor of ZAP. They allow an advantageous application in your production facility, reaching your aims fast, safely and at a high level of quality.
