Drive train optimisation by dynamic torque measurement based on advanced sensor telemetry

In order to optimise a vehicle's drive train, it is imperative to measure the dynamic torque on the drive train during every type of manoeuvre. Such measurement is indispensable for tuning the vehicle and optimising drive train efficiency. This in turn increases driving comfort and fatigue life . When developing new vehicles an optimised drive train is a significant competitive advantage.

Torsiometro a flangia per misura simultanea di coppia e forza assiale

The company Manner Sensortelemetrie has extended its torque measurement flange range, especially developed for the test rig environment, with a new feature. The new rotary combination measurement flange supports the simultaneous dynamic capture of torque and axial force.
As an option, rotational speed can be measured. For simple applications, a data capture and visualisation software is also available.

La tecnologia FLEX apre nuove possibilità alla metrologia nelle trasmissioni.

Due to the growing demand for weight reduction, transmission units have become increasingly compact. That also means that available space for the installation of measuring devices inside the transmission, for example ,operational stability of individual components, like gears, shafts, or synchronising rings is at a premium. Since, however, structural integrity must not be compromised, no additional installation space for metrology can be provided by, for example, simply using thinner materials. In response to these recent demands, Manner has now developed an innovative, flexible sensor signal amplifier based on flex substrate technology for strain gauge and temperature measurement tasks.

The company Manner has developed a new high-precision torque measuring sensor

for torque and power output monitoring at the power take-off shaft (PTO) in

agricultural vehicles. The sensor is particularly compact and fits directly onto the

PTO. It has the degree of protection IP65 and is completely maintenance-free. The

stator is mounted on the shaft and is secured against rotation by means of a chain.

In addition to measuring torque levels up to 5 kNm, the system also provides highresolution

speed monitoring using 180 pulses per revolution. The digital telemetric

transmission technology guarantees 100 percent interference-free transmission of

the measuring signal. Characteristic of the strain gauge based sensor is its high

accuracy down to 0.1% of the measuring range, its extremely low temperature drift in

the range -35 to +125°C as well as its compact construction (length = 50 mm). The

measuring signal can be monitored either as an analogue signal (e.g. 0 to ±10 Volt)

and/or digitally via USB or CAN Bus.
