Magnetostrictive linear position sensors

Senyd magnetostrictive linear position sensor is a type of sensor used to measure linear position by utilizing the magnetostrictive effect. This sensor consists of a magnetostrictive waveguide, which is a wire or rod made of a magnetostrictive material such as nickel or iron.The sensor works by sending a high-frequency electrical pulse down the magnetostrictive waveguide, which generates a magnetic field. When a movable magnet interacts with this magnetic field, it causes the magnetostrictive material to change its shape slightly, producing a mechanical wave that travels back to the sensor head. By measuring the time it takes for this wave to return to the sensor head, the sensor can accurately determine the position of the magnet along the waveguide.


Benefits of magnetostrictive linear position sensor

▶High accuracy and precision: These sensors offer high resolution and accuracy in measuring linear positions, making them suitable for applications that require precise positioning.
▶Non-contact measurement: Magnetostrictive sensors do not require physical contact with the object being measured, reducing wear and tear and increasing reliability.
▶Long lifespan: These sensors have a long operational lifespan due to their non-contact measurement method and robust construction.
▶Fast response time: Magnetostrictive sensors provide real-time feedback on position changes, making them suitable for dynamic applications.
▶Wide temperature range: These sensors can operate in a wide temperature range, making them suitable for use in various industrial environments.
▶Easy installation and maintenance: Magnetostrictive linear position sensors are easy to install and require minimal maintenance, reducing downtime and overall costs.
▶Multiple output options: These sensors can provide various output signals, such as analog, digital, or fieldbus communication, to suit different application requirements.

▶High repeatability: Magnetostrictive sensors offer high repeatability in measuring linear positions, ensuring consistent and reliable performance over time.
