MSI-B Series Linear Position Sensor with Analog Output
Rod-style, high-precision, absolute, non-contact magnetostrictive position sensor with a measuring range from 25 to 3800 mm. Position measurement is performed using ring-type position magnets moving along the waveguide without physical contact. The sensor flange is made of high-quality stainless steel and is designed for long service life.
