Choosing the Right Hardware for Testing in Harsh Environments

Testing in rugged applications often includes testing in extreme temperature ranges, which can add constraints to hardware. Cold-start engine testing, for example, uses a test cell that can drop to -40 °C and requires continuous data acquisition such as temperature, pressure, and other various measurements. Placing hardware that is not built to withstand this range into harsh environments can cause components within the hardware to work incorrectly and result in incorrect data or damage to the hardware.

Products of Tomorrow: August 2016

The technologies NASA develops don’t just blast off into space. They also improve our lives here on Earth. Life-saving search-and-rescue tools, implantable medical devices, advances in commercial aircraft safety, increased accuracy in weather forecasting, and the miniature cameras in our cellphones are just some of the examples of NASA-developed technology used in products today.

Product of the Month: August 2016

Hexagon Manufacturing Intelligence, North Kingstown, RI, introduced the BLAZE 600M non-contact optical measurement solution. The flexible, manually operated system provides ultra-rapid 3D data acquisition and actionable data for measurement, inspection, product development, line tuning, and reverse engineering. The scanner performs feature and surface measurements of parts and assemblies in various sizes, combining high-resolution digital imaging with blue light LED illumination, and does not require surface treatment of metallic, plastic, and composite parts. The system is not sensitive to industrial and ambient light sources or indirect daylight. It is designed for operation in high-vibration industrial environments. The all-in-one system is available in two projection configurations for tasks such as routine dimensional control operations or measurement of workpieces with complex features or challenging material types. Operators can also directly switch between surface data acquisition modes. For Free Info Visit http://info.hotims.com/61064-120

Measurement Terminal

The EL3751 EtherCAT terminal from Beckhoff Automation (Savage, MN) provides measurement as part of a standard I/O system. It acquires data at 10,000 samples per second and provides measurement accuracy of ±0.01% for most interfaces at 25 °C, and 24-bit resolution. Parameterization options are available for the analog input, which supports measurement functions U, I, R, DMS (strain gauge), and RTD. Optionally, measured data can be transmitted to higher-level automation devices with oversampling. The integrated distributed clocks ensure synchronized sampling across the EtherCAT system. Available measurements include voltage, current, resistance, electrical resistance, RTD, strain gauge/load cell, and potentiometer. For Free Info Visit http://info.hotims.com/61064-400

Digital Measurement

Siemens (Munich, Germany) offers Flender Gearlog digital measurement technology for gears that captures values relating to rotational speed, torque, temperature, and vibration using special sensors that record important physical variables. The aim is to compare operational load spectra with the fatigue strength of individual gear unit components over time to match up the gear unit and the working machine for the long term. The system adds up these readings in parallel with machine capacity utilization. The measurement results are logged, saved, and digitally depicted in compressed form. Operators are able to visualize the results at any time or read them out in the form of a dataset. The measurements enable conclusions to be drawn about the applied load and loading capacity of gears, and can be used to identify possible sources of damage, capacity reserves, and overloading in the measured gear.
