The Kistler Group's P109
The Kistler Group has launched the latest addition to the RoaDyn series, the P109 wheel torque transducer. Ideal for use with heavy cars, vans, and SUVs, the new solution offers a high measuring range of up to 9,000 Nm, a low range of 900 Nm and weighs 3.5 metric tons. The solution also has an operating temperature range from –25 to 80°C.
The P109 has strengths in gear development, brake tests, and mandatory safety tests. Additionally, the P109 can also be utilised in the powertrain analysis of NEVs and the evaluation and validation of control and ADAS systems.
A selection of trends in the automotive industry are pushing current measurement technology to its limits, with higher accuracy levels in parameter identification required. Whether it’s shorter model cycles or innovative propulsion concepts, manufacturers are having to drive metrology innovations forward. In addition, heavier vehicles, electric powertrains, and active vehicle dynamics (torque vectoring) all require higher loads than before.
How does the P109 work?
The P109 replaces the rim star of the wheel and transmits the traction torques, captured by piezoelectric quarters sensors, to the onboard electronics located in the vehicle. With a telemetry module transmitting the wireless signal. Mounting Kistler’s wheel torque can be completed in less than 15 minutes and is compatible with a selection of vehicles with the addition of various adapters.
With the previously mentioned two measuring ranges, small traction torques can be accurately measured even with high axle loads.
