Magnetic Sensors and Their Applications

Magnetic sensors can be split into two different types of sensor. This depends on whether they measure the vector components or the total magnetic field. While the results of each sensor vary, the techniques used to create these magnetic sensors use similar aspects of physics and electronic theories. All magnetic sensors work with the Earth’s magnetic field.

The most common technologies used to create these magnetic sensors are the coil, fluxgate, optically pumped, nuclear precession, SQUID, Hall-effect, anisotropic magnetoresistance, giant magnetoresistance, magnetic tunnel junctions, giant magnetoimpedance, piezoelectric composites, magnetodiode, magnetotransistor, fiber optic, magnetooptic as well as microelectromechanical systems-based magnetic sensors.

The reason for the many different types of magnetic sensor is because of the wide range of applications that each sensor has. Some of these industrial applications include linear, angular position and rotation sensing. It is for this reason that contactless sensors are particularly popular.

Magnetic sensors have been developed by companies, such as Crocus, to have high sensitivity, low power consumption as well as having specific design functions depending on the application. This includes high-temperature operation and high-frequency operation. This allows the user to have a reliable and durable magnetic sensor for optimal performance.

There are many different industries in which magnetic sensors are particularly useful. Below is a list of some of the areas that can be benefited from magnetic sensor application.

Power Distribution Units (PDU’s)

Cloud computing and large data analytics is an increasingly large area of new industry. Because of this, there has been an increased production of power distribution units which are the main part of data centers and large servers. Data center infrastructure needs PDU’s to supply AC or DC electrical power to the servers. Magnetic sensors help the PDU provide power filtering to the server and intelligent load balancing. They can also be remotely monitored.

Robotics and Factory Automation

Another recent area of industrial growth is in robotics and the adoption of robotics for factory automation. Magnetic sensors, particularly linear and angular position sensing play a large part in keeping machines in the factory running smoothly. The magnets are used to monitor the motor movements of the robots in terms of precision and accuracy. As the demand rises for faster and more efficient production lines, the role of the magnetic sensor has also evolved to include the use of safety switches and proximity detection.

Energy and Water Appliances

While magnetic sensors are usually used in high tech industries, they can also be used in some of the worlds oldest infrastructure. The sensors can be used for energy and water conservation through intelligent, open/close door detection, fluid levels and contactless sensing. This allows companies to comply with newly updated regulatory standards. In addition to this, this type of sensor can be used on regular appliances such as vacuum cleaners and refrigerators.

Green Energy

Magnetic sensors can be a critical part of contactless current, angular position and switch sensing for green energy power plants such as wind turbines and solar panel farms. Angular position sensing is particularly important for allowing optimal wind power generation while solar combiner boxes benefit from contactless current sensors.
