Two industrial worlds have merged

Traditionally, the worlds of PLC, motion control and control technology on one hand, with measurement technology and “lab applications” on the other, have diverged when it comes to data entry and processing in an industrial environment. Yet divergence always means having to use additional interfaces, which leads to restrictions on efficiency and operating convenience. But […]

Comparison of Class 1 surge protective devices

Lightning current arrestors for low-voltage power systems are usually designed and tested only for use in AC power systems. The performance and operational behaviour of a surge protective device, connected to an AC power system, can be completely different to the performance and operational behaviour of the same surge protective device connected to a DC […]

Antenna matching for RFID reader

This article describes the design method for determining an antenna matching circuit. While there are an infinite number of possible impedance matching networks, this application example focuses on a 50 Ω three element match. A three-element match is recommended as it allows the designer to select the required antenna quality factor, Q, for the application. […]

Video conferencing – bringing together business colleagues from across the world

  State-of-the art information and communication technology (ICT) makes it increasingly easy for people the world over to communicate in real-time.  Perhaps the pinnacle of communication technology is video conferencing (VC) which enables virtual interaction to take place between business colleagues from different sites or remote sites, as if they are situated right next to […]

Protect your assests

 Make sure you understand the do’s and don’ts of process safety, including safety instrumented systems, PLC redundancy, fieldbus technology, field devices, standards and employee skills. Changes in technology have led to a variety of recent developments in process safety, with many suppliers releasing new systems that depart from the past significantly. These do’s and don’ts […]

Accelerating the design of radio astronomy instruments

  When it is complete, the MeerKAT array in South Africa’s Karoo region will include 64 antenna dishes, making it the largest and most sensitive radio telescope in the southern hemisphere. As a forerunner to the Square Kilometre Array (SKA), slated for completion in 2024, MeerKAT will be used by scientists worldwide on a range […]
