The Accuracy Product Development Demands
"It is essential for the product development that design data can be verified in a test bench. We can make sure that what has been calculated takes place in practice. With the data we receive, we can save in production costs. Accurate and real-time torque data is extremely important to us,” says Jouni Teppo, director of R&D for Sisu Axles Inc.
According to Teppo, the biggest advantage of the HBK T40 torque transducers is that they offer a sufficiently high level of torque and accurate measurement data.
With their old test bench, the measuring error could have been several percent; today, they can achieve 0.05 percent accuracy.
Wireless Data Transmission
According to Teppo, one of the benefits of the T40 torque transducers is that torque data can be transmitted wirelessly from the test bench.
The digital torque data signal is transferred wirelessly by telemetry from rotor to stator. The compact size of the T40 allows it takes up little space in the test bench. Together, the size of the T40 and wireless data transmission capability simplify both transducer installation and test bench operations.
Sisu Axles’ new system is also easier to integrate with existing measurement systems and electronics by Fieldbus.
Continuous Availability
"In addition to accurate data and wireless transmission the third important benefit of measurement solution from HBk is, that it is available all the time.
Real-time measurement data is displayed on the PC screen and it can also be stored into the measurement database,” Teppo concludes.
