Emissivity Measurement
Information on Emissivity and Emissivity Measurement Content Overview Table of Contents Emissivity Testing by Eddy Current Emissivity testing by eddy current uses the correlation of the emissivity and sheet resistance which is applied by the architectural glass industry since the late 1980s. Here, the silver coating’s ability to transport electrons is used when interacting with […]
Weight and Grammage Measurement
Weight and Grammage Measurement Content Overview Table of Contents Coating Weight Measurement by Eddy Current The weight of conductive coatings is often measured by non-contact eddy current thin film sensors. This technique induces eddy current into conductive coating, which respond with a electromagnet field (EMF) which is measured by the EMF detectors or directly by […]
Permittivity
Permittivity Measurement Content Overview Table of Contents Permittivity Measurement by High Frequency Eddy Current Testing High frequency eddy current measurement devices can be used not only for characterizing conductivity and magnetic permeability related properties of electrically conductive materials, but also for permittivity characterization of insulators. This is based on the fact that eddy current systems […]
Residual Moisture
Everything About Residual Moisture Content Overview Table of Contents Introduction Residual moisture characterization is crucial for device and cell performance in electro-chemical applications such as batteries, fuel cells, organic photovoltaic and many other applications. Inks, pastes and slurries are usually water or solvent based substances carrying various compounds of particles and molecules. Their material composition […]
Permeability
Permeability Measurements Content Overview Table of Contents Permeability Measurements by Eddy Current Quantitative permeability measurements are not possible with Eddy Current Testing or Barkhausennoise Testing yet, but SURAGUS is applying both technologies to derive related parameters from layers with magnetic content. Thin films with magnetic material content such as Cobalt, Nickel or Iron are used […]
Sheet Resistance
Sheet Resistance Measurement Content Overview Table of Contents Sheet Resistance Measurements by Eddy Current Eddy current gauges are applied for sheet resistance testing since 30 years. Its accuracy and its ability to measure in contactless mode has a special user value. Key benefits of eddy current resistance testing are: Non-contact mode Ultra-fast (20 ms / […]
