Our high-performing LXRD STANDARD small enclosure system, designed with compactness in mind, can fit through a single door. Perfect for measuring smaller parts and samples up to 30 cm. This state-of-the-art instrument is available in a cost effective bare enclosure configuration, or upgraded with numerous options including: a manual XY positioning stage, phi rotation stage (automated triaxial measurement), fully automated 300 x 200 mm travel XY residual stress mapping stage and % retained austenite measurement capabilities. The radiation proof enclosure, automated 400mm Z-axis, MG2000 1200W high-power goniometer, fully integrated chiller, and levelling pads with wheels provide performance and flexibility in a compact package.
The LXRD widebody comes with all of the features of the standard model, but with increased enclosure capacity for measuring larger parts up to 50 cm. With a 500 mm Z-axis and an increased travel of 300 mm for the Y stage, the widebody provides one of the largest measurement envelopes of a stand-alone cabinet system.
LXRD MODULAR MAPPING
The LXRD Modular Mapping system introduces high-powered residual stress mapping to large components. Oversized parts composed of difficult to measure materials such as titanium, are no longer restricted to low-power portable systems. With over 2 meters of measurement space, heavy-duty XY mapping stages, and a removable mapping stage, it has the flexibility to meet all of your complex measurement needs.
The LXRD GANTRY system is PROTO’s largest enclosure system. With a 3.5 meter walk-in enclosure, and long travel overhead XYZ slides, the LXRD GANTRY simplifies measurement of large heavy components by moving the goniometer instead of the sample. Outfitted with a GR2000 goniometer, it adds the flexibility of a built-in phi rotation for triaxial measurements.
The LXRD MICROAREA is PROTO’s full-featured research grade instrument for residual stress measurement. A secondary chi rotation stage enables measurement in true side inclination (in addition to omega and modified side inclination). An XY mapping stage, phi rotation stage, video microscope, and x-ray beam aperture sizes down to 30 microns provide advanced tools for your microarea residual stress measurement needs.
A laboratory and factory floor star performer, the LXRD has been designed for heavy duty around-the-clock operation. Extremely fast, accurate and reliable, the LXRD offers the highest return on investment in the industry. Measurements can be performed in as little as a minute.
Laboratory Residual Stress and
Retained Austenite Measurement Systems
Built with both your safety and the long term protection of your instrument in mind. Our instruments are compliant with ANSI N43.2 regulations providing full radiation protection. An informative safety interlock panel directly linked to the flow sensor, x-ray tube, high voltage power supply and door interlocks provides thermal and operational status diagnostics. X-ray and shutter beacons conveniently notify the operator of the status of the x-ray beam.
PROTO’s proprietary position sensitive scintillation detectors (PSSD) provide unsurpassed speed, stability and a wide 2θ range. Unlike other x-ray detectors, they do not deteriorate with exposure to x-rays. No expensive replacements required. The detectors can be quickly positioned between Omega or Modified Side Inclination geometry. Two detectors for accurate sheer stress determination. Available in standard and extended 2θ range.
At the core of every LXRD system is the powerful yet easy to use PROTO XRDWin 2.0 software. A comprehensive Windows®-based data collection and stress analysis package with features such as: linear and elliptical regression, Dolle-Hauk, and triaxial methods. Advanced peak fitting functions: parabolic, gaussian, pearson VII, cauchy, centroid, centered centroid, and mid-chord. Graphical display of peak intensity, breadth, FWHM, and sin2ψ plots provides informative easy to read results. Software utilities for XEC determination, principle stress, material removal, depth of penetration, retained austenite, pole figures, and single crystal stress complete the package.
High Performance Goniometer Bearing
X-ray Beam Aperture Kit
Integrated X- ray Tube Cooling Systems
All of our LXRDs have features that make them easy and convenient to use. A high performance goniometer maintains ASTM E915 accuracy in a low maintenance design. The manual focus pointer enables accurate positioning of the goniometer in complex geometries. The automated focus pointer provides convenient focusing of large residual stress maps. A wide variety of x-ray beam apertures are available including: round 0.2, 0.5, 1.0, 2.0, 3.0, 4.0 mm and rectangular 0.5x3, 1x3, 0.5x5, 1x5, 2x5 mm. High stress standards, zero stress powders & RA standards ensure accurate system results. Integrated cooling for a self-contained instrument.
X,Y, Phi Mapping Stages
Residual Stress Mapping
Automated Retained Austenite Measurement
XEC Determination via 4-point Bend
Residual Stress Mapping is available on all LXRD models, providing a comprehensive picture of the residual stress state of your part. As the originators of residual stress mapping, PROTO is a leader in the field. Automated Retained Austenite as per ASTM E915 enables characterization of %RA in steels as low as 1%. X-ray elastic constant determination (XEC) ensures automated residual stress measurement material calibration as per ASTM E1426. Pole Figures created using the LXRD rotary stages can be used for preferred orientation analysis, single crystal orientation, and single crystal stress measurement.
