DESCRIPTION
With its compact, bearingless, maintenance-free design, the
TF Torque Flange Sensor from Magtrol brings many appealing
advantages to torque measurement applications. The TF’s high
torsional rigidity supports direct mounting on the machine shaft
or flange, avoiding the use of couplings on one side. This allows
easy integration into a test system, shortens the overall length
of the test bench and reduces costs.
Based on strain-gauge technology, the TF Sensor’s precise
telemetry system enables highly accurate signal transmission.
A signal amplifier mounted in the measuring flange amplifies the
measuring signal, modulates it to high frequency and transmits
it inductively (via the HF transmitter) to the conditioner. In the
conditioner, the digitized torque signal is transformed into an
analog output signal of ±5 V DC. Rotational speed can be
measured and converted to a TTL output signal with the optional
speed sensor.
The contactless design of the Torque Flange Sensor permits
a gap of up to 5 mm (typically 2 or 3 mm) between the
rotor antenna and HF transmitter, which makes the signal
acquisition insensitive to any axial or radial misalignment.
Another advantage of this torque measurement system is its
insusceptibility to signal interference since the antenna does not
need to be looped around the measuring flange. Additionally, a
protective cover can be mounted close to the TF Sensor with
no effect on the signal.

ASSEMBLY
APPLICATIONS
12
TF Torque Flange Sensors measure both static and dynamic
4 torque on stationary and rotating shafts. They are used in
general combustion engines, electric motor and gearbox test
benches; and can also be mounted inline for active torque
monitoring of transmissions, powertrains, wind generators, gas
turbines, boat engines, etc.
