Emerson Process Management’s Fischer Fieldvue DVC6205 remote-mount digital valve controller is suitable for applications where accessibility, extreme temperatures (up to 120°C/250°F), extreme vibration or confined space make integral mounting difficult or impractical.
High-precision pressure sensors based on resonating techniques have been manufactured for many years but use large transducer components and often have unwieldy media isolation techniques. This paper from GE Measurement and Control presents a MEMS resonant pressure transducer (RPT) that is produced using a flexible fabrication route to allow pressure ranges from 1 bar to 700 bar in fully oil-isolated hermetic packages without compromising sensor performance. The key aspects of the fabrication ..
An analysis of as-found, as-left and production data for a large sample (more than 250) of multifunction calibrators from a few months old to more than six years old shows that the instrument is generally very conservatively specified and that artifact calibration does return the instrument to essentially the same level of accuracy it had when manufactured.
Limit switches for liquids are used throughout process engineering as standard. For economic reasons, it is recommended that all technical solutions should be reduced to one universal measurement principle. In this article from Endress and Hauser, the requirements of such a universal limit switch are discussed and summarised using a vibronic limit switch as an example.
The basic principle of the fuel cell is simple, yet its power spectrum is more than convincing: fuel cells are highly efficient, low in emissions and virtually noise free. Before affordable, commercially viable fuel-cell systems can be produced, however, intensive research and development efforts are needed. Test stands for the analysis of entire fuel-cell systems or single components such as bipolar plates or membrane electrode assemblies play a key part in this process. Bürkert Fluid ...
Technical note: thermal-imaging cameras — a fast and reliable tool for testing solar panels download
The use of thermal-imaging cameras for solar panel evaluation offers several advantages. Anomalies can clearly be seen on a crisp thermal image and — unlike most other methods — thermal cameras can be used to scan installed solar panels during normal operation. Thermal cameras also allow large areas to be scanned within a short time frame.
The dielectric breakdown of HV bushings is one of the most frequent failure causes for power transformers. This white paper from Omicron Electronics discusses new diagnostic methods to assess the dielectric condition, including the analysis of the dielectric response and partial-discharge (PD) measurements, and includes several case studies. Practical examples illustrate the importance of capacitance, dissipation factor and particularly dielectric response measurements on HV bushings.
Robot spot welding units are widely used in the highly automated production lines of the automotive industry and by its suppliers. To meet the stringent quality requirements for welding while ensuring the 100 per cent availability and reliability of the individual components and welding robots, controlled optimised cooling of the welding is imperative. According to Bürkert Fluid Control Systems, operators must therefore be in a position to quickly and accurately detect any leaks in ...
This user’s guide from GE Sensing contains general information about moisture monitoring techniques. System contaminants, moisture probe maintenance, process applications and other considerations for ensuring accurate moisture measurements are discussed.
