gravity. This determined whether the weight of the car was distributed well on each wheel. Using wireless technology allowed the racing
team to convert voltage readings from their sensors to engineering values. The measurement data output provided high precision readings and high resolution so the team could make the final adjustments to the angle and weight distribution of the vehicle, optimising it for the FIA World Touring Car World Cup.
PREVENTING WATER LEAKAGE AND WIND NOISE In a different instance, again supporting an automotive racing team, wireless technology was used to improve the accuracy of the door seal gap measurement to prevent water leakage and wind noise in the vehicle. Limiting wind noise is of the upmost importance for the safety of the driver as the cockpit of a race car is known to be one of the noisiest workplaces on Earth, as a result of the wind noise and 140 Db engine. Previously, the measurement of the door
seal gap area was performed with time intensive tools and methods that relied heavily on operator skill. The automotive original equipment manufacturer (OEM) wanted a faster measurement system that was capable of measuring the door seal gaps between two adjoining panels. They also wanted instant visual feedback of the data, which could be stored digitally to
understand the fit of the doors over time. To solve this problem, the OEM used the
WISEgap system, incorporated with T24 wireless telemetry technology. The WISEgap system is a sensor-controlled wireless gap measurement system that made it possible to instantly record door fit conditions in product, engineering and development environments. The system also supported wireless measurement in multiple modes: static, real time dynamic and high speed dynamic. The flexible nature of the WISEgap system with T24 meant that the OEM could self-calibrate and work across all the different models and closures. Using the system improved
accuracy and time savings for setup and measurements. What once took two hours per door could now take five minutes per door. By wirelessly measuring door seal gaps, the motor team was able to prevent water leakage and wind noise issues in all stages of production as well as conduct analysis and testing on the car that was previously impossible.
