High-precision test stand torque measurements with the XTREMA TORQUE by new calibration laboratory
To provide high-precision, simple torque measurements on the test stand, MANNER has developed the XTREMA TORQUE sensor.
MANNER: Test stand operation for the testing of combustion engines, hybrid and electric motors requires high-precision measuring equipment. Friction power measurements in particular place very high demands on the measuring equipment. In order to meet these demands, the transducer has a standard accuracy class of 0.05.
Particular emphasis has been placed on the robustness of the measuring equipment.

The high nominal speeds of up to 24,000 min-1 are no challenge for the XTREMA Torque design. It uses a DIN flange pattern that is compatible with HBM torque sensors and allows for easy integration into both new and already-built test stands with existing infrastructure.
The large distance between rotor and stator of up to 10 mm is particularly noteworthy.
In combination with the protruding pick-up, it affords strong protection against damage in case of bearing damage, as well as great ease of installation. Even lack of precision during assembly will not affect the transmission quality.
The optional hollow shaft supports complex test stand set-ups. Oil supply at the centre or actuator systems are not a problem.
The series includes the following ranges: 200 Nm; 500 Nm; 1 kNm; 2 kNm; 3 kNm; 5 kNm and 10 kNm.
Another special feature of our solution is the optional high temperature resistance of the measuring flange of up to 160°C and the optional protection rating IP67.
This also ensures a high fatigue limit.
The XTREMA TORQUE sensor includes a stator pick-up unit with built-in evaluation electronics, which provides the torque sensor with inductive feed and stands out for its compact design. With this design type, the interfaces for frequency output (F= 10 +-5kHz) and voltage outputs U= 0 +-10 V are available as standard. The system runs absolutely maintenance-free.
With the optional version (separate stator), the evaluation unit may be installed inside the control cabinet. This allows for the operation of the XTREMA Torque measuring flange and the pick-up at higher ambient temperatures in the range between -40°C and +160°C and with oil immersion.
The associated tube design evaluation unit can output the classic analog signals at 0.. ±10V / 4..20mA or use the frequency output, but it also supports the output of digital signals via EtherCAT, CAN, Ethernet, EtherCAT or USB.
As a result, MANNER not only has high-precision measuring equipment to prove the accuracy of the new measuring flange generation XTREMA, but also an essential tool for the further development of torque measuring technology.
The required standards of DIN EN ISO / IEC 17025 and the requirements of the DIN EN 9000 series have already been implemented today.
The aim is to be able to offer calibrations according to the DAkkS standard in the near future. The DAkkS certification process is already underway.
MANNER also offers services for customers. Improved processes and resource extensions result in attractive prices and short delivery times.
Today, calibrations with six calibration stands are possible at MANNER to meet this requirement.
10 - 200 Nm test bench
Test bench for miniature transducer applications, such as in spindles
1 kNm test bench
Test bench for customer-specific transducers such as pulleys and flanges with a calibration range of up to 1 kNm
5 kNm (2 benches)
Test bench for flanges and side shafts, transmission flanges or for example transfer shafts for aircraft landing flap systems
Due to the variable adjustment of the length, short flanges as well as transducers with lengths of up to 3 m can be calibrated.
50 kNm test bench
Vertical inline test bench, mainly for flange applications.
The generous vertical radial tip size even enables the calibration of bulky special transducers.
500 kNm test bench
Test bench for standard torque transducers and special transducers for shipping, large gearboxes or wind turbines can be manufactured and / or calibrated by MANNER.
In Germany, only PTB (Physikalisch-Technische Bundesanstalt) and MANNER are able to calibrat this torque range.
