Application note: developments in battery stack voltage measurement download

Linear TechnologyWed, 30 Jul 2014

Automobiles, aircraft, marine vehicles, uninterruptible power supplies and telecommunications hardware represent areas utilising series-connected battery stacks. These stacks of individual cells may contain many units. In such systems, it is often desirable to accurately determine each individual cell’s voltage. Obtaining this information in the presence of the high ‘common-mode’ voltage generated by the battery stack is more difficult than might be supposed.

Amplified piezoelectric actuator APA with composite shell

Technical article: compact and efficient piezo actuation chain for aeronautical applications download

Cedrat Technologies S.AMon, 28 Jul 2014

Many past and ongoing studies are focusing on the use of piezo-actuators for aeronautical applications. One of the trendiest topics is the use of such devices for active flow control in aircraft in order to reduce fuel consumption and noise. However, the implementation of such systems in aircraft suffers a lack of maturity with respect to aeronautical constraints, which are high efficiency, compactness and light weight.

Cryo-characterisation test bench

White paper: cryogenic piezo characterisation and integration download

Cedrat Technologies S.AMon, 21 Jul 2014

This paper details a test bench design and the results obtained with CNES on two-piezo ceramics stacks from two distinct suppliers. Integration into dedicated cryo actuators is also proposed as well as the associated cryo performances. The use of such cryo-compatible actuators is detailed in a fine steering tip-tilt mechanism designed to reach very high resolution and stability for the ESA EChO space mission. 

Wet chemical analysis

Application note: total digestion with HF in Multiwave Go complexation of fluorides download

Anton PaarWed, 16 Jul 2014

In wet chemical analysis, complete dissolution of the samples is required for the determination of the total concentration of elements. Especially for silicate-containing samples, the usage of hydrofluoric (HF) acid is a necessity. In order to digest and extract all metals quantitatively from matrices containing silicates and oxides, normally digestion with hydrofluoric acid is carried out in a two-step procedure.

The need to combine two areas of physics: electromagnetics and mechanics

Technical article: magneto-vibro-acoustic analysis: a dedicated context inside Flux 11.2 download

CedratFri, 11 Jul 2014

A design office’s ability to assess and control vibration and noise levels generated by an electric motor during the design stage is a key asset — particularly for ensuring the end user’s comfort. This is especially true for electric powertrains on electric vehicles, and also when looking for higher performance in terms of power, efficiency, reliability, and — obviously — reduced material costs linked to the supply of magnetic equipment. During the past three years in the context of ...

Application note: Fluke discusses leakage current measurement basics downloadweblink

Fluke (UK) — Industrial ToolsTue, 8 Jul 2014

In any electrical installation, some current will flow through the protective ground conductor to ground. This is usually called leakage current. Leakage current most commonly flows in the insulation surrounding conductors and in the filters protecting electronic equipment around the home or office. So what’s the problem? According to Fluke, on circuits protected by residual current devices, leakage current can cause unnecessary and intermittent tripping.

Technical article: conformance testing ensures clear, open communications download

CLPATue, 1 Jul 2014

The benefit of using networks that are built to open standards is that it removes the constraint of having to buy equipment from a single supplier. Instead, products can be purchased from many sources, confident that they will ‘plug and play’, communicating and working with everything else on the network because it has all been built and tested to the same standard.
