The 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 Sensor s precise telemetry system enables highly accurate signal transmission. 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 ± 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 mm (typically 1 to 3 mm) between the rotor antenna and HF transmitter, which makes the signal acquisition insensitive to any axial or radial misalignment. nother advantage of this torque measurement system is its insusceptibility to signal interference due to the fact that, unlike other designs, the antenna does not need to be looped around the measuring flange. dditionally, a protective cover can be mounted close to the Sensor with no effect on the signal. pplictions Torque Flange Sensors measure both static and dynamic torque on stationary and rotating shafts. They are used in general combustion engine, 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. 1
