Piezoresistive absolute pressure sensor employs direct chip exposure technology to provide superb linearity, minimal hysteresis and an extremely high natural frequency
Accelerometer for high temperature operation
Designed for use in aggressive environments such as automotive engine bay and under vehicle applications, aerospace subsystem vibration testing and industrial quality control
Integrated digital processing and RF telemetry transmission of data from the force sensors in the moving wheel to the signal-conditioning module in the vehicle, eliminates the need for noisy, difficult to set-up and maintain slip-ring transmission.
A single, compact stator, usually fitted within the vehicle wheel arch, determines wheel rotation angle, provides inductive power for the rotating electronics and receives the transmitted data.
The elimination of cables and complicated fixing arms on the outside of the vehicle allows testing to be carried out safely on public roads.
The six-component wheel force measuring system registers the three forces and three moments acting on the wheel.
This data is then digitised by the in-built electronics eliminating errors due to electrical/electronic interference, temperature variations and transmission noise.
Lightweight sensors and electronics allow the RoaDyn wheel to have weight and inertia characteristics little different from that of a standard wheel.
Vehicle performance, steering and braking are not affected ensuring that measuring errors are not introduced during dynamic testing.
Although lightweight, RoaDyn measuring wheels are robust and operate reliably in extreme conditions of dust and splash water.
In addition to the range of standard wheels covering most applications, the sensors and electronics can be built into wheels of any size and material.
The Windows-based user interface, run on a laptop PC, allows data to be checked, analysed and stored for future use.
In addition, data interfaces are available for all standard data acquisition systems.
