New from Norbar Torque Tools, the TTT torque tool tester is a highly specified but easy to use instrument which, when connected to appropriate transducers, is ideal for a huge range of torque testing applications.
For maximum flexibility, the TTT has interfaces allowing any two external transducers to be connected simultaneously.
Selection between the transducers is made instantly by a switch on the side of the instrument, dramatically reducing the time taken to check the calibration of a range of torque tools.
The TTT works with Norbar's "smart" torque transducers or most standard mV/V calibrated transducers giving the TTT a vast range of potential applications.
Norbar's own transducers span a torque range from 0.04 to 100,000Nm.
Norbar "smart" transducers have built in memory and are recognised by the TTT.
There are no calibration factors to enter or amplifier units to insert and, as soon as the instrument is switched to a "smart" transducer, it will be ready to use.
Accuracy is typically better than Class 1 (+/-0.5% of the reading) across the primary classification range.
For transducers that are not "smart", the procedure is also very simple.
The TTT can store the calibration parameters for up to 20 transducers and, once entered into the memory, they can be easily recalled using an index numbering system.
The TTT features a pictorial display panel and a membrane keypad for the simple selection of the numerous operating modes which are available to suit the majority of torque applications.
The control panel uses diagrams of various types of torque tool and the operator simply presses the button corresponding to the tool under test.
The TTT's automatic set up procedures then do the rest, selecting the appropriate test mode and frequency response.
To eliminate operator errors, all user selectable features have password protection so that when it is issued to the test area only the required modes of operation and units of calibration are enabled.
The TTT gives a visual indication of a low, high or pass test result and up to eight target values can be set.
In addition an RS232 and serial data output port is provided so test results can be printed or downloaded to a PC.
The instrument can be mains or battery operated and a rechargeable NiMH battery pack is included which will give approximately 16 hours of operation.
When used on mains power, a display screen back light will come into operation and the battery pack will be recharged.
Each TTT is supplied with a UKAS certificate of calibration so that, provided the external transducer is itself calibrated, full system traceability is maintained.
Transducer calibrations are carried out to BS7882:1997 in Norbar's own UKAS accredited laboratory.
Norbar began making torque wrenches in Banbury almost 60 years ago, and has unrivalled expertise in the field of torque control and measurement.
With the launch of the TTT, Norbar offers a complete range of torque test and calibration tools to complement its hand and power torque wrenches and multipliers.
