Wiegand Effect Energy Harvesting

The “Wiegand effect” was discovered almost fifty years ago and has been used successfully in several specialized applications. However, its full potential for energy harvesting and signal generation has received only limited recognition. With recent enhancements to the energy output from Wiegand devices and the emergence of a new generation of ultra-efficient electronic chips for wireless communications, the technology is showing significant promise, especially in the exciting new area of the Internet of Things (IoT). UBITO, a member of the FRABA Group of technology companies, is leading research and development projects aimed at fulfilling this promise.

Sensors As Tough as You Are

If your environment is dirty, hot, wet, or corrosive your requirements may have some similarities with that of the construction industry.

Accuracy, Resolution and Repeatability

There are several key terms that are critical to specifying the optimal position sensor for a given application. This application note defines these key terms and how they relate to the sensor’s role in the overall system performance. It is important to consider that precision is very much a system issue and can be dominated by mechanical errors such as eccentricity. This paper discusses the most significant mechanical error for rotary applications (eccentricity) and presents eccentricity tolerant position sensor solutions.

Chips, Chips & Chips

What semiconductors, snacking and gambling all have in common: Encoders!

There has been a lot of talk lately around the global ‘chip’ shortage. Even social media last month was filled with cartoons of engineers asking Santa for semiconductors for Christmas. Rotary encoders such as the DS-130 by Netzer Precision are an important part of this ‘chip’ production. Accuracies exceeding 0.004 degrees, 21 bit resolution and a 90mm ID ensure that component placement can be done accurately and consistently.
