The XtreMA High Precision Torque Flange Series includes the ranges of 50 N·m, 100 N·m, 200 N·m, 500 N·m, 1 kN·m, 2 kN·m, 3 kN·m, 5 kN·m und 10 kN·m.

The demand for ever higher accuracy and reproducibility for efficiency determination or friction power measurement of aggregates is becoming more and more frequent. The optimisation of machines, drive trains, gearboxes etc. is being pushed further and further. However, the potentials are becoming smaller than was the case a few years ago. High-precision measuring equipment is needed to capture the improvements. The aim is to exploit the last ounce of potential through optimisation, comparable to a diamond cut.

In accordance with this development and requirement, we have made it our task to further develop our already accurate XtreMA torque flange and improve the accuracy by a factor of 3. The new design is called XtreMA HP. This further development enables even more accurate measurement results.

The new optimised design has made a breakthrough in accuracy. We do not accept a trade-off. Strength values and the influence of parasitic forces do not impress the measurement signal. Now, due to the outstanding accuracy, it is possible to perform extremely precise measurements even in a partial load range.

You have a measuring task where the previous measuring flanges have failed? We have heard this many times. Our XtreMA HP flanges have proven that extremely harsh conditions neither intimidate nor bring them to their knees.

This new transducer is extremely tough – ready for any challenge!
Due to the overload design of 400%, the torque sensor offers both the measurement of continuous loads and the short-term detection of load peaks in dynamic operation.
The special short design with the low rotor weight and the extremely low mass moment of inertia allows nominal speeds of up to 25,000 min-1 to be achieved without any problems.

Optionally, the flanges can be operated in the temperature range of -40°C… 160°C.
Another special feature is the electronic compensation of the zero-point error Tk0 and the nominal value deviation Tkc. This allows a constantly high accuracy to be achieved, virtually independent of the ambient temperature. This is because which test stand is operated under constant operating conditions.
The DIN flange pattern used, which is mechanically absolutely identical to HBM torque sensors, allows the direct replacement of HBM flanges. The simple integration into new test benches, but also into existing test benches with existing infrastructure – a retrofit.

The field-proven flange pattern of all measuring ranges is retained.

Flexible and proven!
Despite this new technology on the rotating side, it remains with the proven different and also flexible stator configurations. The systems are fully compatible with the XtreMA generation already on the market.
The stator antenna or stator unit is compact and in the familiar design it allows an air gap of 3 mm up to 10 mm in the standard version. There is no ugly enclosure of the rotor.

This has proven to be extremely advantageous in practice, as assembly errors or vibrations do not lead to collisions or even failures. Moreover, even imprecise assemblies pose no challenge at all to the transmission quality.

Go dual, go digital!

In addition to the classic analogue signals with 0…±10V / 4..20mA or the frequency output, a stator unit in tube design also allows the output of digital signals via EtherCAT, CAN, Ethernet.

No space left? No space, go compact!

MANNER also offers a compact evaluation unit with and without speed detection. The alignment of the speed sensor is an extremely easy plug & play solution by means of an LED signal.

Too hot, too cold? Go XtreMA!

The temperature resistance with remote pick-up (stator antenna) allows operation under the harshest environmental conditions from -40°C up to 160°C.

Swimming in oil? Go oil-proof!

The “hollow shaft” option allows complex test stand concepts. Oil supply in the centre or actuator is no problem. On request, the XtreMA HP torque sensor is available with and without speed detection.

Don’t let them fool you!

MANNER – technology guarantees class accuracy from -40°C to 160°C

High-precision measuring equipment is required for test bench operation for testing combustion engines, hybrid and also electric motors.
As is well known, class accuracy is only defined for an ambient temperature range of 22°C +/-10°C. Outside this temperature range, the error is significantly greater.

The new optional compensation technology for Tk0 and Tkc guarantees the specified class accuracy over the entire specific operating temperature range (-40°C…160°C). This means that there is no deterioration even outside the temperature range of +/-10 °C defined by the class accuracy.

The cherry on the cake

Friction power measurement in particular places high demands on the measuring equipment.
To meet these demands, the XtreMA HP has an accuracy class of better than 0.02%.

This means that the XtreMA HP is in no way inferior to the HBM T12 and others.
