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.

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.

Redundant Encoder Options

In the world of rotary encoders, modern non-contact sensing technologies and high MTBF (Mean Time Between Failures) specifications are standard. However, in critical applications, redundant sensors are still a necessity. When selecting a solution, several criteria need to be considered, and fortunately, various options are available to simplify the task. Understanding Redundancy in Encoders The […]

Facing the Inevitable: Sensor Obsolescence, Mitigation Strategies, and Alternatives

Obsolescence. If its only difficulty was remembering how it is spelled it wouldn’t be so bad. And whether you’re trying to replace a sensor that has failed with age or are a manufacturer who can no longer source an important sensor, obsolescence of an inexpensive sensor can create extremely expensive headache. At Everight Position we help customers to understand the causes of sensor obsolescence, explore mitigation strategies and find alternative solutions.
