Magnetic sensors are known as the sensors that are used to detect changes or movements within a magnetic field such as direction, strength, and flux. There are various types of detection sensors that can work on some characteristics like pressure, light, and temperature. These sensors are categorized into two groups. The first one is utilized to calculate the total magnetic field, and the second one is utilized to calculate vector components or parts of the field. The vector component in the magnetic field are individual sections and the methods that are used for producing these sensors involve a mixture of electronics and physics.
Enrgtech offers a great deal of high-quality magnetic sensors such as solid-state sensors from some of the known brands in the market.
Magnetic Sensors-Switches (Solid State)
Magnetic Sensors-Switches (Solid State) are involved in this category make use of the solid-state technology to detect the presence of a magnetic field in excess of some particular magnitude or sign and then give out a two-state output which tells us about the absence or presence of the magnetic field.
They are different from reed switches that perform similar functions by using moving mechanical parts. As well as from the linear or compass type solid-state device which gives you a variable output telling you about the strength and/or orientation of the applied magnetic field.
Types of Magnetic Sensors
There are three main classified types of magnetic sensors that have some dissimilarities among them such as low field, earth field, and bias magnetic field sensors.
Applications of the Different Types
Low Field Sensors
Low field sensors are utilized to detect extremely low values of the magnetic field like 1 uG to 10-4 Tesla. Some good examples of this are fiber optic, nuclear processions, and SQUID. These sensors are majorly used in both medical and nuclear fields.
Earth Field Sensors
The magnetic range for this type of sensor is from 1uG to 10G. Earth field sensors use the magnetic field of the earth in various applications such as vehicle and navigation detection.
Bias Magnet Field Sensors
These sensors are utilized to detect massive magnetic fields that are above 10 Gauss. Most of the sensors that are utilized in industries use permanent magnets as the source of the chosen magnetic field. As the name indicates, they will bias otherwise magnetize the ferromagnetic items which are close to the sensors. This type of sensor primarily includes GMR sensors, hall devices, and reed switches.
