Torque transducer DRT 4 / Torque and Angle transducer DRT 5
1 - CE MARKING
Manufacturer:
Address:
Declares that this product has been assessed and complies with the requirements of the
relevant CE Directives when used with Desoutter Readout Devices.
2 – SUMMARY
The rotary torque transducer DRT 4 is designed to measure the torque output of any non-impact assembly
tool. The unique construction gives long life to the brushes with minimal maintenance requirements. The
transducer is suitable for use with impulse type assembly tools. Due to the technology of the transducer, it
may only be used with SIGMA2001, SIGMA2D, DELTA4000, DELTA4D, DELTA5000, DELTA5D or
DELTA 1D/6D/7D readouts. An alternative version DRT 5 is available with an angle measurement
encoder which allows, with a DELTA5000 or DELTA5D or DELTA6D/7D, the measurement of the angle
of rotation in addition to torque. These models are not sensitive to the cable length between the transducer
and readout because the "torque" or "torque and angle" signals are converted to a numerical value in the
transducer. The exclusively numerical link between the units provides reliability for the measurement and
immunity from any external interference. No settings are necessary and therefore no risk of error is
possible when connecting one of these transducers – they are automatically recognised due to an internal
memory which stores the identity, characteristics and maintenance data.
3 – OPERATION
Select a suitable size of transducer appropriate to the maximum torque rating of the tool used. Tool and
socket should be secured onto the transducer with a pin/O-ring device or with a male square detent pin.
Connect to the readout, select an appropriate operating mode and then operate the tool in the normal way.
In the interests of accuracy, it is essential to maintain the correct alignment between the fastener, the
transducer and the power tool. When using these rotaries with a tool and reaction bar, the effective radial
position of the reaction point should not be less than the figures given in the table. Failure to observe this
requirement and also the maximum torque rating may cause irreversible damage to the transducer. The
rotary transducer with angle encoder may also be used with any tool except impact types. Angle
measurements may be made with impulse tools but restriction on the maximum acceptance speed of the
readout may limit accuracy. Since the angle encoder measures the angular position of the torsion shaft
relative to the transducer body, it is important to hold the body still as the tool is operated. If the male
square detent pin is not required, this may be removed with a stepped (for location purposes) punch of Ø
2.3mm for the 1/4", Ø 3.95mm for the 3/8" or 1/2" squares and Ø 6.3mm for the 3/4" or 1" square drives.
