Alignment System

The AlignPROTM system is designed to assist machine operators when
measuring and adjusting load string alignment. The software monitors
the output from strain gauges mounted on either flat or round
alignment cells. The outputs are used to calculate bending due
to angular and concentric alignment errors.
For each of these components, the direction and magnitude of the
bending is displayed both numerically and graphically. When the
software is used in conjunction with the Instron AlignPRO fixture, the
software identifies which adjustments are required and displays in
real time the effect of the adjustments, enabling accurate machine
set-up in just a few minutes.

Features and Benefits
• Real-time concentricity and angularity adjustment under load
• Avoids errors being introduced by having to re-tighten load string
t after adjusting alignment
• AlignPRO system saves time compared to manual
t alignment methods
• Improves accuracy of test data by ensuring load string is correctly
t aligned before test
• Compact and portable electronics can be carried around the
t laboratory from machine to machine
• Utilizes USB technology with simple plug and play operation –
t no special cards or ports are required within the PC or
t laptop computer
• Supports both eight and twelve gauge alignment cells
• Electronics and software compatible with existing Instron®
t alignment fixture
• Designed to comply with the requirements of ASTM E 1012

Principle of Operation

The electronics supplies each of the strain-gauges with a stable
reference voltage. Each strain gauge output is fed back to a data
acquisition unit and made available to the AlignPRO™ software as a
real time strain signal.
The AlignPRO software combines the strain signals using calculations
as specified in standards such as ASTM E 1012 and presents
misalignment information both numerically and graphically on screen.
The information on the AlignPRO screen updates the strain readings
constantly, allowing adjustments with the optional AlignPRO fixture to
be made and read immediately. After completion of the adjustments,
a report is generated.

AlignPRO Alignment Fixture

Software for Materials Testing

When the strain-gauged alignment cell is installed in the grips, any
misalignment in the load string will cause the alignment cell to bend.
