Magnetostrictive sensors are devices used to measure the displacement of an object with extreme accuracy. The magnetostrictive sensor works on the principle of magnetostriction, which is the ability of certain materials to change their dimensions under the influence of an external magnetic field.
The magnetostrictive sensor consists of a magnetostrictive element, a permanent magnet, and an electrical device.
The magnetostrictive element is made from a ferromagnetic material that responds to a magnetic field. The permanent magnet is placed adjacent to the magnetostrictive element, and when the element is subjected to a magnetic field, it causes a change in its shape.
The electrical device measures the changes in the element’s shape and converts them into a digital signal, which is then used to calculate the displacement of the object being measured.
The advantages of magnetostrictive sensors are their high accuracy, low power consumption, and wide range of applications.
The magnetostrictive sensor is ideal for measuring small displacements in a wide range of industries, including automotive, aerospace, and biomedical.
It can also be used in many different environments, including extreme temperatures, pressures, and vibrations. Furthermore, the sensor is shockproof and resistant to corrosion and dirt.
Overall, magnetostrictive sensors are an innovative and reliable way of measuring displacements with extreme accuracy.
They offer a wide range of applications, and the low power consumption and the ability to withstand harsh environments make them an ideal choice for many industrial applications.
The Global Magnetostrictive sensor market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
The company Novotechnik, which develops and produces potentiometers, rotary and linear position sensors, and other electronic components, has introduced new magnetostrictive linear hydraulic and pneumatic position sensors.
Position sensors in the series are available in plug-in and screw-flange types, and their technology is based on magnetostrictive technology. For touchless operation, a magnetic marker in the shape of a ring glides up and down the shaft of the sensor.
The TM1 Series of magnetostrictive position sensors from Novotechnik offers a high degree of accuracy, infinite mechanical life, and ease of application integration.
For situations requiring the highest level of precision for position measurement in tight places, Balluff introduced a new generation of magnetostrictive sensors in rod and profile designs.
Different BTL magnetostrictive position measuring system versions from Balluff provide different feature combinations based on the design of the product. There are two different performance classes (B1 / C1) within each of the corresponding sensor families.
For the application itself, this makes it simple to configure and develop the ideal sensor system. Standard applications can benefit from basic functions and a good price/performance ratio offered by the BTL position measurement systems of performance class B1.
Particular applications for the incredibly compact magnetostrictive sensor in the new tiny rod design include lift and hoist technologies, forming and rolling facilities, and hydraulic cylinders for position feedback. Moreover, wind turbine rotor blade tilt angle monitoring and injection moulding machines employ BTL micro rods.
This receives a strong and long-lasting part for the application with its housing composed of stainless steel that resists corrosion. A long service life is guaranteed, and downtime is decreased, by the non-contact and wear-free measuring. For magnetostrictive position measuring systems with profile designs, a variety of variations are also available, each of which can be customised individually.
