Magnetostrictive displacement sensor is a built-in stroke displacement sensor for hydraulic cylinders. It features a built-in 16-bit D/A converter, which can convert the absolute position of the vernier magnetic ring into a standard 4โ20mA current signal or 0โ10V voltage signal in real time and with high precision. The output signal is linearly related to the effective measurement range. SUCH displacement sensor has a measurement range of 100~1500mm, an operating temperature range of -40~85โ, and supports multiple output modes including 0โ5V, 0โ10V, 4โ20mA, and start-stop. It operates on a 24VDC power supply (-15%~+20%) and is suitable for high-precision displacement measurement applications in hydraulic cylinders and various industrial and engineering machinery.
A magnetostrictive displacement sensor is a high-precision linear position measuring device based on the magnetostrictive principle. It measures the absolute position of a magnetic ring in a non-contact manner and features high precision, high reliability, and long lifespan.
Magnetostrictive displacement sensors are based on the magnetostrictive effect. When a current pulse propagates in a waveguide wire and interacts with the magnetic field generated by a position magnetic ring, a torsional stress wave is generated in the waveguide wire. This stress wave propagates at a constant speed towards both ends. By measuring the time difference between pulse emission and stress wave return, the absolute position of the magnetic ring can be accurately calculated.
Widely used in hydraulic cylinders, construction machinery, industrial automation, injection molding machines, metallurgical equipment, mobile hydraulic systems, and other fields.
