Torque measuring device
DATAFLEX®16 - High accuracy for low torques
The recently developed DATAFLEX
®
16 extends the existing range of contactless
torque measuring shafts and is available for measuring torque ranges of 89 [lb-in],
266 [lb-in] and 443 [lb-in].
The torque is measured using well-approved technology of wire strain gauges
combined with the latest electronic components. The torque signals are processed
without contact at a high resolution of 24 bit achieving an accuracy of 0.1%.
Supplementary to torque measuring the size 16 has a speed encoder providing two
offset impulse with a resolution of 360 pulses per revolution.
DATAFLEX
®
22, 45, 85, 140 - Patented technology
The DATAFLEX®torque measuring shafts sizes 22 to 140 measure the torques
without contact and free from wear. Their secret is a patented measuring method
acquiring the twisting of the torsion shaft by measuring the quantity of light. For that
purpose the light is directed through two disks the transparency of which is
amended proportionally to the torque. The overall electronics are situated in a
stationary housing to make sure that no signals have to be transmitted by the
rotating shaft and the torque is available accurately with a high band width of 16kHz.
This can measure and analyze highly dynamic processes accurately.
The analog output values are available both as a voltage signal from 0-10V and as a
current signal from 4 - 20 mA. In addition, a speed encoder is integrated providing a
signal at a resolution of 60 impulse per revolution.
Connection housing DF2 - All inclusive
The connection housing DF2 can easily be combined with all DATAFLEX
measuring shafts disposing of a retainer for top hat rail assembly as well as terminal
screws for an easy connection of external devices.
The following features save the purchase of expensive measuring amplifiers and
converters:
l The torque output can be filtered over 5 steps so that short torque peaks in the
display can be reduced.
l The pulse signal of the speed output can be configured both for 5V (TTL) and
24V (HTL). This makes the speed signal compatible for data logging boards and
SPS Controls.
l In parallel with the pulse signal an integrated frequency voltage converter
supplies a DC voltage from 0-10V proportionally to the speed, the scaling of
which can be changed individually. This makes an expensive counter superfluous
so that the signal can either be processed as a voltage or can be displayed.
l A direction signal indicates the rotational direction of the drive (with DATAFLEX
16).

Couplings adjusted to every application
With all DATAFLEX®sizes we recommend the servo lamina coupling. RADEX®-NC
and the steel lamina coupling RADEX
quickly integrated, having a high stiffness. In general, it is also possible to use zerobacklash plug-in couplings such as ROTEX
coupling.
