January | February

The SAE 2001 World Congress provides industry suppliers the opportunity to showcase their products, services, and technologies to the global automotive community. Here's a preview of what some of the exhibiting companies plan to introduce or display - as of mid-January - at this year's event scheduled March 5-8, 2001, Cobo Center, Detroit, MI.

Data-acquisition module

A-DAT's ICP-48 data-acquisition module for the M3-Integra family of mobile data-acquisition systems allows up to 16 three-axis accelerometers to be connected. The module is fully parallel in design with one 16-bit A/D-converter per channel. Ranges and filters are software programmable. Customer-specific, four-pin connectors such as Microtech or Lemo are available. The basic M3-Integra can house two ICP-48 modules (96 channels), and with the extended docking station, four additional modules (192 channels). More channels can be added in steps of 24 or 48.

Leak detector

Alcatel's ASM 142 helium-sniffing leak detector offers a sensitivity of ²0.1 ppm, response time of ²0.5 s, and floating auto-zero to detect small leaks. Features include built-in calibrated leak with temperature compensation, auto-calibration in sniffing mode that compensates for temperature and age, voice synthesizer for increased user-friendliness, and four levels of operator interface. The device is suitable for outboard leak testing. Its high-vacuum pump rotates at low speed to allow pump movement during operation. The unit can also be set on hydrogen to accommodate applications requiring hydrogen as a tracer gas.

Gasket material

CorkRubber from Amorim Industrial Solutions is suitable for gasket applications. The material provides good torque retention, flexibility, and sealability characteristics even when exposed to brutal temperature extremes. Via the firm's Partnership 2001 program, ideas and information are shared between company and customers to create optimized individualized solutions.

Electrical component tester

The Bauer HB1000 Electrical Component Tester verifies devices and test connections. Its powerful processor and high-speed analog inputs allow it to measure the static and dynamic behavior of the components being tested. The HB1000 is suitable for powertrain harnesses, ignition systems, and injector systems. A 10-A circuit capacity permits testing electrical components at their operational load. The device's modular design features one or more backplanes. Each backplane can accommodate 12 industrial power driver boards. Each plug-in board contains two identical, independent test circuits designed to measure static and transient voltages. These circuits are configured with resistance and capacitance values based on the load and polarity required by the tested device. Bauer PCS Software is used to monitor circuits and set loads, creating conditions that enhance testing and defect analysis.

Optical-analysis software

Breault Research Organization's ASAP 7.0 optical-analysis software contains features for facilitating interior and exterior lighting. View-driven radiometric analysis calculates illuminance and luminance. System geometry guides the choice of view and eliminates the need for complicated commands. Results are stored in ASAP distribution files for further analysis. A volume fluence features the amount of flux passing through any region (voxel) in space, whether or not an object is there. It enables viewing of the light distribution on a plane that cuts through any part of an optical system to identify low-efficiency areas of a lightpipe. An expanded bidirectional scattering distribution function-fitting capability interactively fits realistic functions to measured data from a range of surfaces including polished glass, vacuum-molded plastics, and painted surfaces.

Modular data-acquisition system

Whether in mobile applications or in the field of test-rig control, Caesar DataSystems' modular data-acquisition front-end MOPS collects data from analog and digital transducers simultaneously through up to 1024 channels. At the same time, digital data streams from in-vehicle bus systems or PCM data coming from telemetry links can be recorded. Due to its built-in intelligence and its interactive user interface, the MOPS supports the test engineer by shortening the procedure of setup and calibration. All features, parameterization, data acquisition (with online graphic), and analysis can be controlled from a PC using standard Windows software. The MOPS palette includes amplifier modules suitable for all transducer types commonly in use.

Fast response analyzers

Cambustion Ltd.'s HC, NOx, and CO2 Fast Response Analyzers have a 10-90% response time of approximately 1 ms, making them suitable for resolving transient engine phenomena at high engine speeds. They yield information on transient fueling calibration, gear change misfires, tip- and tip-out fueling, driveability, and burn quality. These analyzers enable engine researchers and calibrators to reduce cold-start emissions, optimize GDI, accurately control EGR, and develop NOx traps.

Anti-alias filter

The CR9052DC from Campbell Scientific is a high-performance, anti-alias filter module that extends the capability of the CR9000, a portable, battery-powered data-acquisition system. The module includes six anti-aliased analog measurement channels with differential input ranges from ±20 mV to ±5 V. Each of the six channels has its own programmable-gain instrumentation amplifier, pre-sampling analog filter, and 16-bit sigma-delta analog-to-digital converter. An on-board digital signal processor provides real-time, programmable anti-alias filtering and down-sampling before passing the results to the unit's main processor. The total system measurement throughput is 100,000 measurements per second. This rate is sustainable while storing data on interchangeable PC cards. A single clock synchronizes the A/D converters from every module.
