The application of magnetoelectric and Hall effect speed sensors in Power equipment

In modern industry, the efficient operation of power equipment such as generator sets, diesel engines, power turbines and windmills cannot do without the precise measurement of flywheel speed. Accurate monitoring of the flywheel speed not only ensures the stable operation of the equipment, but also optimizes energy utilization efficiency and enhances overall performance. Magnetic-electric speed sensors and Hall effect speed sensors, with their outstanding performance and wide application advantages, have become ideal rotational speed measurement devices in the above-mentioned fields.Velocity sensor

Magnetoelectric speed sensor

The magnetoelectric speed sensor is based on the principle of electromagnetic induction and measures the rotational speed of the flywheel by detecting changes in the magnetic field. When the gear ring on the flywheel passes through the sensor, the change in the magnetic field will generate a periodic voltage signal in the induction coil, thereby achieving precise measurement of the rotational speed. This sensor does not require an external power supply, has a simple structure, is easy to install, and can work stably in harsh industrial environments.

Hall effect speed sensor

The Hall effect speed sensor measures the speed of the flywheel by detecting changes in the magnetic field based on the Hall effect principle. When the magnetic gear ring on the flywheel passes through the sensor, the Hall element senses the change in the magnetic field and converts it into an electrical signal. After processing, a pulse signal is output. This sensor features high precision, rapid response and non-contact measurement.

Application scenarios

1. Generator set: By monitoring the operating parameters of the generator set, such as rotational speed, power, and frequency, data support is provided for the automatic control system to achieve precise control of the generator set, thereby enhancing power generation efficiency and stability. The real-time monitoring and early warning function can effectively reduce the equipment failure rate, decrease the downtime and maintenance costs caused by sudden failures, and extend the service life of the generator set. The combination of sensors and automatic control systems can achieve remote monitoring, automated operation and intelligent management of generator sets, improving management efficiency and operational safety.

2. Diesel engines: Speed sensors, camshaft sensors, crankshaft sensors, etc. provide precise speed and position signals for ignition and fuel injection control of the engine, enabling the engine to maintain optimal performance and efficiency under different operating conditions. By precisely controlling fuel injection, diesel engines can achieve the best combustion efficiency under various operating conditions and reduce fuel consumption.Diesel generator sensor

3. Power turbine: The rotational speed sensor can measure the rotational speed of the turbine in real time and feed the data back to the control system to precisely control the rotational speed, ensuring that the turbine operates stably at the rated speed and preventing damage caused by overspeed or low-speed operation. Real-time monitoring and precise control of parameters such as rotational speed, temperature and vibration can effectively enhance the operational stability and reliability of power turbines and reduce downtime due to faults.

4. Wind turbine: The rotational speed sensor and the torque sensor are respectively used to measure the rotational speed and output torque of the wind turbine and the generator, ensuring that the wind turbine operates within a safe rotational speed range and achieving precise control of the power generation. By real-time monitoring of parameters such as wind speed and direction, the operating status of wind turbines is optimized, enabling them to efficiently capture wind energy under various wind conditions and enhance power generation efficiency.Wind turbine generator sensor

Comparison and Selection

When choosing a speed sensor, a comprehensive consideration should be made based on the specific application scenario and budget. If the equipment has restrictions on power supply, a magnetic-electric speed sensor may be a better choice. If higher precision and rapid response are required, Hall effect speed sensors have more advantages.

Whether it is a magnetic-electric speed sensor or a Hall effect speed sensor, they all play a significant role in power equipment such as generator sets, diesel engines, power turbines and windmills. By precisely measuring the flywheel speed, these sensors can ensure the stable operation of the equipment, optimize energy utilization efficiency, and enhance overall performance.
