The Electron Machine Corporation has been designing X-ray gages and mill control systems for more than forty years. Our gages use X-ray pulse technology to provide good measurement results with lower radiation. The SXR—225 is the latest in solid state design that breaks with the past line frequency response limitations. Operating at 225 hertz, its fast response time keeps pace with the industry’s faster processes and need for more throughput with improved quality and lower costs.

HOW IT WORKS

The SXR-225 X-ray Gage consists of three major components:

1) A source unit to generate finitely controlled X-rays
2) A solid state detector to measure non-absorbed rays
3) A console of advanced modular design for control and readout of the source and detector

The KV rating of the source unit is chosen to match product thickness and material.

In operation, the emitted X-ray pulses penetrate the material to be measured. The amount of radiation reaching the detector is reduced by the absorption of the product which in turn is a function of its thickness. The detected signal is sent to the display/control console for alloy compensation and/or thickness display.

APPLICATIONS

• INPUT / OUTPUT GAGING OF ROLLING MILLS

• WALL THICKNESS OF CYLINDERS

• SHEET THICKNESS AND PROFILE

• CUSTOM DESIGNED SYSTEMS FOR SPECIAL REQUIREMENTS

ADVANTAGES
The most important reasons to choose Electron Machine Corp.
pulse-type X-ray gages are:

1) X-ray generation can be produced at the optimum level for the most desirable signal to noise ratio and stability considerations.

2) When an X-ray gage is turned off radiation is not present. Isotope gages may have radiation half lives expressed in decades.

3) Government regulations may be less stringent for operation of X-ray gages versus isotope gages.

4) Non—contacting measurement offers better performance on irregular surfaces and poor operational environments.

5) Most importantly, Electron Machine Corp. X-ray gages have a long standing record of rugged design, reliability, and good value.
