Summit engineering technology provides digital torque testers and data collectors [model dtt opta]. These digital torque testers and data collectors comes with a world of choice, features and flexibility to the tool test environment, with interchangeable transducer modules, built-in printer option, and software features tailored to the application requirement. These options allow the dtt opta to be configured to closely match the user requirements, and a selection of transducer modules can be made available to the operator to cover a broad torque range. In common with the opta product family, dtt opta`s range of software features can be individually specified giving variations from a simple no-frills readout to a comprehensive audit tool with display of torque curves and specialist measurement routines. The basic dtt opta performs bi-directional measurement of torque in track, peak, 1st peak and pulse count is also measured. Cycle time duration can also be displayed. Time and date stamped readings can be set to print automatically on the optional built-in printer or external printer. The easy-to-read display gives a simultaneous view of all relevant information during the measurement process, while the simple alphanumetic keypad enables fast data entry when required.
