Overview

About the Edge

Non-destructive analysis on any dimensions sample for indoor and outdoor analysis.

Edge is the new GNR portable residual stress analyzer. It has been designed focusing on exceptional portability lightness, easiness to set up and outstanding performances.

Edge is a portable Theta/Theta X-ray diffractometer: it allows performing reliable measurements on production samples and specimens to determine residual stress, retained austenite and to investigate alloys structure and phase composition.

The instrument is compliant to ASTM E915, UNI EN 15305 (residual stress standard practices) and ASTM E975 – 13 (retained austenite standard practice).

Edge includes everything needed taking advantage of its portability and lightness for making residual stress and retained austenite measurements by X-ray diffraction in a portable manner.

It has been designed to be a fast and reliable solution for Quality Assurance and Quality Control practices in manufacturing process for both laboratories and field use.

Edge is a flexible diffractometer that can be provided with different set-up:

Edge complies with the statutory requirements regarding X-ray, machine and electrical safety.

Maximum X-ray safety with radiation level significantly below the annual dose limit for general public (1 mSv/year) following ANSI N43.3 – 1993 and other industry standards for open beam X-ray operation.

Software

Operating software

GNR proprietary software X-Sense® for Edge supports several tasks of analysis, from Data Acquisition, having the full control of all the process and hardware settings (generator and tube, detector, measurements set up) to Data Analysis, calculating the residual stress or retained austenite values.
An extremely easy to use software for Uni-axial, Bi-axial and Tri-axial residual stress analysis has been developed in compliance with ASTM E915 practice and UNI EN 15305.
