High Precision Multi-channel PXIe Systems Realize More Efficient Wind Tunnel Testing

Wind tunnel testing is widely used in large-scale aerodynamic design projects. Even so, the requirement for large numbers of sensors over large areas of the devices to be tested presents major challenges in data acquisition and retrieval. The article discusses use of multi-channel PXIe systems to achieve fully synchronous, high-efficiency, highly precise measurement solutions. Attributes include: PXIe technology providing effective single-system integration with multiple combinations of a wide variety of sensors PXIe platforms’ PC-based structure delivering easily deployed superior computing power along with networking capability, minimizing development time and simplifying setup

Refractory Metal Fasteners for Extreme Conditions: The Basics

There is a wide range of metal fasteners commonly available for standard applications, but what if your application is at very high temperature or in a highly corrosive environment? Sometimes the more commonly available fasteners are just not up to the job. Enter high-performance refractory metal fasteners. Refractory metal fasteners – nuts, bolts (also called screws or machine screws) and washers – are ideal for situations that involve high temperature, high voltage, magnetism and harsh corrosive environments.

Reliability Testing of GORE® Protective Vents in LED Luminaires

Outdoor lighting systems are designed with sealed housings to protect against environmental contaminants. Atmospheric conditions such as temperature shifts and relative humidity present challenges to the reliability of outdoor luminaires. Changes in ambient temperatures can lead to significant pressure differentials. Over time, pressure on the enclosure seals can cause them to fail and allow contamination and/or water to breach the enclosure. This shortens the life of the luminaire by damaging the wiring, leads and other electronics of the power supply driver and the LEDs. The moisture also reduces light efficiency and can cause condensation to form on the lenses and reflectors.

How to Maximize Temperature Measurement Accuracy

Thermocouples are the most versatile and widely used devices for temperature measurements. Most test engineers are aware of the measurement errors caused by thermocouples but not always about the errors caused by the measurement system itself. This technical note will focus on the lesser known and important aspect called "Self-Calibration" and how it can be used to overcome errors in temperature measurement.

Re:Vision: A New Paradigm for Mid-Lifecycle Design Changes

For decades, replacing key components during the mid-lifecycle design refresh was seen as simply too costly and burdensome. Changes had to wait until the next generation. Today, technology changes too fast to wait to add new capabilities. Fortunately, there are other options. With the right partners and suppliers involved, a mid-lifecycle component change can provide cost savings and greater performance capabilities. This white paper explores when and why a mid-lifecycle component change makes sense.
