Hall Effect Gear Tooth Sensors: an Introduction

Hall Effect Gear Tooth Sensors: an Introduction

Comments 0 Comment

Introduction Hall Effect Gear Tooth Sensors are an established and inexpensive technology for the measurement of position and rotational speed. By sensing the magnetic flux variation in the air gap between a magnet and passing ferrous gear teeth, they generate a pulse signal with a frequency proportional to rotational speed. Their quick response time, high operating temperature range as well as their contamination, and EMI immunity have turned Hall Effect Gear Tooth Sensors into popular sensing solutions for many different…

Source: Euronews, (2022)   Wind has long been used as a renewable energy source for centuries, from ship sailing to grain milling. And in modern times, wind power is the fastest growing renewable energy technology in the utility sector, exceeding the growth of solar power, hydro power as well as bioenergy. For instance, the global annual wind electricity generation has increased exponentially from 433,770 Gwh in 2011 to 1,588,586 Gwh in 2020, with 93% of the capacity being onshore wind…

We are pleased to share with you our article “Optimization of the Processing Time of Cross-Correlation Spectra for Frequency Measurements of Noisy Signals”, published in Metrology 2022, 2, 293–310 of MDPI, on June 10th, 2022. Accurate frequency measurement plays an important role in many industrial and robotic systems. However, different influences from the application’s environment cause signal noises, which complicate frequency measurement. In rough environments, small signals are intensively disturbed by noises. Thus, even negative Signal-to-Noise Ratios (SNR) are possible…
