In November 2014, the International Conference on Measures and Weights will likely agree on a new definition of the Ampere as one of the three basic dimensions of electricity. Just in time before the conference, a group of scientists from Physikalisch-Technische Bundesanstalt (PTB), the German Institute of Metrology, succeeded in developing something like the new gold standard for current: The device does not only generate a single-electron current but is also capable of measuring it - without relying on resistance and voltage as auxiliary values.
Products and solutions for the field of renewable energy have long been part of VAC's portfolio. For many years the Hanau-based company has supplied AC-DC-sensitive differential current sensors (DI sensors) for use in solar inverters as per EN 62109. In addition, VAC has identified further exciting areas of application for the future in modern advanced electronics.
Photodiodes are one of the most popular sensor types for many light-based measurements. Applications such as absorption and emission spectroscopy, color measurement, turbidity, gas detection, etc., all rely on photodiodes for precision light measurement.
New generations of electronics engineers, new groups of users with non-electronics background are increasingly utilizing complex test instruments. This constellation has led to a transformation of the user interface in lab instruments, and even to new ways to utilize these devices.
