The T40FM digital torque flange is capable of measuring highly dynamic processes from 15 to 80 kN m up to a bandwidth of 6 kHz.
The short design and very low weight of the T40FM ensures a small mass moment of inertia. The secure, digital measured value transfer enables high interference immunity and maximum accuracy.
The T40FM is optimally suited for torque measurements in large engine, gear and rolling road test benches.
The key features of the T40FM digital torque flange are:
- The T40FM features extremely high torsional stiffness and the reduced mass moment of inertia resulting in a significantly better natural torsion frequency of the torque flange. Hence further expansion of the resonance frequency is possible up to higher values during dynamic measurements in test bench applications. This enables the reserves up to the resonance frequency to be increased for a number of operating conditions. The entire construction is protected, failures are prevented and hence costs are saved.
- The mechanically robust measuring unit of the T40FM is capable of withstanding a peak load of up to 660%, depending on the nominal (rated) measuring range, so it can absorb torque peaks. Hence test bench construction costs are saved and safety and the overall availability of the plant are improved.
- Since the strain gauges are present in the measuring unit of the T40FM torque flange excellent protection is ensured against environmental factors such as dirt and moisture. With protection up to IP54 ensured, the T40FM is an optimal choice for applications in tough industrial environments.
- The T40FM has an optional rotational speed measuring system. This is far superior to an optical system in rough industrial operations; contaminants, such as dust or oil, will not affect the signal. Furthermore, an optional reference pulse is now available that further improves the magnetic rotational speed measuring system.
- The T40FM torque flange ensures secure, digital transmission of measured values. It is equipped with a special sigma-delta converter that digitalizes and transmits the measured values from the rotor to the stator.
- The digital TMC interface in the torque flange stator supports communication with the TIM40 torque interface module. Several fieldbuses are supported such as CAN, Profibus-DP or EtherCat. This simplifes integration in Fieldbus-based test bench designs.
