Portable torque indicator stores multiple traces

A Crane Electronics product story
Edited by the Engineeringtalk editorial team Aug 7, 2006

The TorqueStar Opta portable torque indicator and data collector enables the operator to view and store rundown traces of torque versus time, and can now store multiple torque traces.

When encountering difficulties with certain joint applications, quality departments rely on a graphical torque analysis of the actual fastening procedure to solve the problem.

Crane Electronics' TorqueStar Opta is a portable torque indicator and data collector which enables the operator to view and store rundown traces of torque versus time.

A new software module now allows the TorqueStar Opta to save multiple torque traces.

These can be downloaded to a PC or laptop for closer comparison and analysis at the end of a test series.

There is a number of graphical representations to choose from, ranging from a single graph to the overlay of multiple curves.

The operator, however, does not have to wait to download the graphs to a PC for a first "ad-hoc" or initial analysis.

It is possible to see the graph of the last tightening process on the TorqueStar Opta unit itself.

A zoom function also enables a more detailed view of the curve points.

The TorqueStar Opta can be used with compatible wrenches, stationary and rotary transducers.

Crane's "plug and play" system avoids setup failures between these and the data collector.

Potential applications can be found in a range of environments ranging from assembly to laboratory.

These would include graphical analysis of new joints during destruction testing with a wrench in a quality laboratory as well as power tool testing of the application on the production line.
