Torque transducer ART 4 / Torque and Angle transducer ART 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 ART 4 is designed to measure the torque output of any non-impact assembly
tool. The unique construction gives long life with minimal maintenance requirements. The transducer is
suitable for use with impulse type assembly tools. It may be used with SIGMA2001, DELTA4000 or
DELTA5000 readouts. An alternative version ART 5 is available with an angle measurement encoder
which allows, with a suitable DELTA5000 readout unit, the measurement of the angle of rotation in
addition to torque. Whatever the transducer model selected in the SIGMA2001, DELTA4000 or
DELTA5000 readouts, no adjustment is required when replacing a transducer with another one from the
same model. The output sensitivity and nominal load are set to the same value when changing from one
transducer to another so as to avoid possible measurement errors.
3 – OPERATION
Select a suitable size of transducer appropriate to the maximum torque rating of the tool used. This should
be secured onto the tool output drive shaft and a socket fitted to the male square drive with the free pin.
Connect to the readout, select an appropriate operating mode, and then operate the tool in the normal way:
refer to the readout User Manual if necessary. 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 ART 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 restrictions
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 Ø2.3mm for the 1/4", Ø3.95mm for the 3/8" or 1/2" squares and Ø6.3mm
for the 3/4" or 1" square drives.
