‘4-20ma Signals’

An Engineeringtalk guide

Start with the news release ABB drives reduce swimming pool energy bills from ABB Automation Tech (Drives and Motors), which we summarised at the time by saying "ABB drives have helped a UK holiday park operator save GBP77,000 a year on energy bills for its swimming pools. ". Several months prior to that, we featured the news release SGS offers acoustic emission testing package from SGS SA - Industrial Services: "SGS is offering an acoustic emission testing (AET) package, which allows users to locate structural defects and to monitor the material for discontinuities.".

In November 2009, we covered the news from Gas Data - take a look at GFM416 provides onsite biogas measurement which says: "The Atex-approved GFM416 gas analyser from Gas Data is ideal for anaerobic digester applications requiring on-site measurement of biogas.".

Take a look also at the news release from SolidWorks Corporation, Solidworks CAD software used in blind car, as well as TVOC monitor can be installed without barriers from Ion Science, and Giga-tronics software suits EW signal simulation from Giga-tronics.
