The RS420 torque sensor is a key part of a system designed to monitor, analyse and help understand how noise, vibration and harshness affects drivetrain systems.
Datum Electronics in partnership with George Kingsbury Engineering, have been included within a US Patent award for a system designed to monitor, analyse and help understand how noise, vibration and harshness (NVH) affects all manner of drive train systems.
The system uses the RS420 torque sensor from Datum Electronics, which has been developed to give a much more accurate way of capturing the data required than other technologies currently employed such as acoustic monitoring, accelerometers and laser techniques.
The RS420 has been proved to outperform all of these by a long way with high quality, reliable data delivery.
Datum Electronics can now provide transducers able to measure at up to 90,000 samples a second.
This effectively means that the torque signal can be deeply analysed, and reveal a wealth of previously unavailable information about the system under test.
Also by using a torque transducer, it makes it possible to get as close as possible to the source data without interference from other drive line components.
Datum Electronics systems and torque sensors can now provide a lot more than devices, which mostly only provide just simple average torque.
Married with powerful signal processing and interfacing technology, it is now even possible to analyse individual component performance and condition, even so far as being able to detect wear of gearbox components down to actual teeth within it.
