AEI's What's New at SAE 2002
GPS sensor
The MicroSAT GPS sensor from Corrsys-Datron Sensorsystems performs dynamic, noncontact vehicle speed and distance measurement. It uses military-grade global-positioning data to provide slip-free speed measurement at 0.1% accuracy. The unit is also suited to off-road testing, as well as testing and measurement of watercraft and aircraft. It is designed to enable a single person to conduct performance tests quickly and easily. It can switch automatically between acceleration and brake test screens for data viewing. Through an acceleration run, the system analyzes speed gain and stores the data as a separate test. It also logs braking tests. The acquired data can be viewed as a series of individual tests or as an overall plot of the entire test run. The sensor is available in three configurations, with the capacity to accommodate up to 16 additional external sensors.
Multi-protocol analyzer
Dearborn Group's Python is a multi-protocol analyzer that is designed to interface with all OBD networks including CAN, J1850 PWM, J1850 VPW, ISO 9141-2, and KWP 2000. The versatile networking tool communicates with a PC by the use of a USB port or RS-232 cable. It is intended for a variety of applications including end-of-line testing, diagnostics, and development. The Python's hardware includes an API, which makes it suitable for users to write their own software applications.
Pressure transducer
The PMP 317 Series from Druck Inc. is a group of rugged, on-vehicle pressure sensors that is suited for all chassis and engine pressure measurement requirements, including fuel system, transmission, manifold and turbo pressure, air-conditioning, braking system, and crank-case pressures. The unit can be powered directly from the vehicle battery, even during the start cycle. It is suitable for measurements where temperature cannot be controlled and reliable, high-performance measurement is required.
Release coatings
DuPont TraSys water-based release coatings are environmentally safe, enabling molders to meet even the most stringent existing and anticipated environmental regulations. TraSys is free of volatile organic compounds and ozone-depleting chemicals. DuPont also has eliminated chlorinated solvents from its release products rather than replace them with carcinogenic solvents or flammable alcohols. The releases are manufactured using highly effective, stable raw materials and are mixed in a unique blending process to yield the desired durability. Product consistency and reliability keep production running smoothly, while competitive pricing, combined with the high levels of performance and longevity, provides the most cost-effective release available for elastomer molders.
Air-fuel ratio meter
ECM's AFRecorder Model 1200B air-fuel ratio (AFR) meter is a compact, handheld meter that measures AFR using an exhaust-mounted, wide-range UEGO sensor. Programmable for all fuel types and compositions, it can display AFR in Lambda and %O2 units. Other features include an analog output, a programmable EGO simulator, and large, built-in nonvolatile recording memory. With the supplied PC software, the meter will record and plot in real time. The model is one of six AFR meters offered by the company.
Steel wheel
The Kühl Wheel, patented by The Epilogics Group and manufactured by Hayes Lemmerz Intl., is a fabricated steel wheel that offers the styling flexibility of an alloy wheel at the cost of a conventional steel wheel. Its all-steel construction and enhanced brake-cooling characteristics make it especially suited for heavy-duty applications such as trucks and SUVs. Its corrosion resistance and low cost make it ideal as a winter wheel in snow-belt regions.
