 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 industries like automation, automotive, and renewable energy. 
      Figure 1: Hall Effect Gear Tooth Sensor     
  In gearbox wind turbines , gear-tooth design deficiencies and gearbox failures occur at specific bearing locations and later advance into surface wear, bearing debris as well as misalignments of gear teeth. These result in scheduled shutdown time for maintenance work, which is costly and time-consuming. Hall Effect Gear Tooth sensors are utilized to proactively optimize the operation of gearbox wind turbines. They monitor the speed and position of the gears and consequently reduce maintenance work and operation costs. 
     
  In this article , we take a closer look at this useful technology.

 Current Sensing is an important process for the evaluation, control, and diagnosis of electrical systems. Traditionally, you use current sensing for circuit control and protection. Due to technological progress, people use current sensing in performance optimization and monitoring as well. Thus, you can find Current Sensors in many application fields like: 
 
 Current and voltage control 
 Inverter 
 Servo motor 
 Generators 
  Automobile electronics &amp;nbsp; 
 Telecommunication 
  Battery management systems  
 Wind turbines 
 photovoltaic-equipment 
 etc. 
 
 One commonly used method is resistive current sensing using a shunt-resistor. It exploits the voltage drop on the shunt-resistor to calculate the current flowing through the resistor using the formula 
   
 But resistive current sensing has a few disadvantages. First, there is a lack of electrical isolation between the power-handling and measurement circuit. As you measure the voltage drop at the terminals of the resistor, you have to integrate the current-sensing instrument into the circuit being monitored. So, due to safety concerns, you can only use resistive current sensing in the high-voltage application, if you can guarantee the separation between the power-handling circuit and measurement circuit by using additional electronics. Furthermore, the voltage drop on the shunt-resistor leads to energy loss. To minimize the losses, the resistor value should be as low as possible. 
 Because of these issues, Hall Effect Current Sensors are widely used as well. They are a reliable solution for non-contact current measurement with high accuracy. The galvanic isolation between the sensor and current guarantees a high degree of safety. Furthermore, Hall Effect Current sensors have a simple structure and low energy losses. 
  Our first article  in &quot;sonnecy.org&quot; provides a summary of the basics of Hall Effect Current Sensors. The article describes its working principles as well as the difference between Open-Loop and Closed Loop Sensors.

                 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 10 th , 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 in practice. As a result, frequency measuring methods that can be used for low SNR signals, are in great demand. In previous work, the method of cross-correlation spectrum has been developed as an alternative to Fast Fourier-Transformation or Continuous Wavelet Transformation. It is able to determine the frequencies of a signal under strong noise and is not affected by Heisenberg’s uncertainty principle. However in its current version, its creation is computationally very intensive, thus its application to real-time operations is limited. 
 Thus in this article, we present a new way to create cross-correlation spectra for frequency measurements of signals with a low signal-to-noise ratio, which aims to reduce processing time to enable real-time application without significant accuracy loss. A new method is developed as well as simulation results are provided in the paper.
