Two DuPont™ Zytel® HTN PPA products help tyre pressure monitoring system stand up to pressures of the road

20.02.2008
SmarTire Systems Inc. tapped DuPont Automotive and high performance characteristics of DuPont™ Zytel® HTN PPA and Zytel® HTN PPA SuperStructural resins for a lightweight and durable casing for SmarTire’s new externally-mounted Tire Pressure Monitoring System (TPMS) used as part of the SmartWave® system for commercial trucks.

The new SmartWave® external, valve stem-mounted TPMS uses Zytel® HTN PPA SuperStructural resin for the housing and Zytel® HTN PPA for the cap. “Protecting the SmartWave electronic sensors inside the housing is paramount and the best way to create a non-permeable seal that withstands the rigors of external road conditions is through laser welding,” said Dan Jones, assembly manager for DuPont Automotive. “Our laser-welding leadership and competency in Asia Pacific really helped ensure we create a permanent joint in this inaugural project despite the dissimilarities of the two materials.”

The new SmartWave® external, valve stem-mounted TPMS uses two Zytel® HTN PPA resins, and marks DuPont’s first use of laser welding to assemble dissimilar products in North America. The non-permeable seal created by laser-welding provides all-weather protection for the sensor while the Zytel® HTN PPA surround is heat resistant and durable.

Zytel® HTN PPA SuperStructural resins offer the rigidity, durability, plus impact and heat resistance required to meet heavy tire spin loads, intense pressure levels that can reach 200 PSI and heat in the brake assembly area that can reach 200 °C. The average commercial vehicle travels one million miles in five years.

The new SmartWave® external TPMS is due to be released to the market in 2008 and offers installation benefits for retrofit applications.

“Our customers have asked for an external TPMS that can effectively provide performance cost data, is convenient to retrofit and is durable enough to withstand the harsh conditions that commercial trucks face,” said Shawn Lammers, VP Engineering, SmarTire Systems. “The reply? SmarTire’s external TPMS.”

Two of the top three commercial truck market’s financial concerns surround fuel economy and tire costs, both of which a tire pressure monitoring system can help manage. By integrating with the vehicles’ existing J1939 communications network, the system can relay vital information to the driver through a variety of display mechanisms and even communicate information remotely to a central routing depot through telematics systems.

Due to the size of the unit, the available surface area and the cost of the labeling process, as well as exposure to outside elements, the units are all laser-etched with bar code and text information. This will ensure that the units will continue to carry all of their necessary information for tracking and information purposes.

SmarTire develops and markets proprietary advanced wireless sensing and control systems worldwide under the SmartWave® trademark. The company has developed numerous patent-protected wireless technologies and advanced tire monitoring solutions since it was founded in 1987. The company’s proprietary SmartWave® platform provides a foundation for the addition of multiple wireless sensing and control applications. The initial product release on the SmartWave® platform is SmartWave® TPMS, which leverages on the company’s background and knowledge in tire monitoring solutions.

Im Focus: Manipulating Electron Spins Without Loss of Information

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.

For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...

Im Focus: The proton precisely weighted

What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.

To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
