System performs a regression analysis of transducers and reports the coefficients of the best fit polynomial, standard deviation, uncertainty, and the percent error at each point
Admet, a provider of integrated mechanical testing systems, announces the MTestWindows force calibration system for calibrating load cells in tension or compression.
The system is said to be ideal for transducer manufacturers who want to improve the throughput in their calibration labs.
It performs a regression analysis of force transducers and reports the coefficients of the best fit polynomial, standard deviation, uncertainty, and the percent error at each calibration point.
The MTestWindows force calibration system also allows calibrations to be performed according to ASTM E74 where the load cell is rotated 120 degrees between each load cycle and a curve is fitted to the average of the three cycles.
It can be installed on any one of Admet's electromechanical or hydraulic testing systems and can be retrofitted to virtually any existing testing machine or press.
It includes an external interface box that controls the movement of the load frame in tension or compression and acquires load, deflection and millivolt data from the force transducer under test.
Test control.
MTestWindows employs a high speed 32-bit microprocessor for precise closed loop control of electrohydraulic and electromechanical test frames.
It uses a proportional integral derivative control algorithm and features monotonic, cyclic and segmented control profiles.
Test reporting. MTestWindows generates single test reports that include a load vs millivolt plot including best fit polynomial coefficients, standard deviation, uncertainty and a table showing percent error at each calibration point.
All data can be exported in Ascii delimited format for easy import into common spreadsheet and database programs.
The system is easy to learn and easy to use, says Admet.
Unlike competing Windows-based systems, a new MTestWindows user can be performing tests in less than a day, it claims.
Admet also offers free phone support for the life of the product and free upgrades for the first year.
" MTestWindows force calibration system's all in one solution and ease of use speeds throughput of transducer calibration labs," commented Richard Gedney, Admet founder and president.
" No more logging the load vs millivolt data on one computer, transferring it to another computer, importing it into a spreadsheet program, manually determining the best fit polynomial, then typing the results into a report.
"We generate the report automatically after each test.
"It also works with virtually any testing frame and lab information management system."
