Magnetostrictive linear position sensors for industrial hydraulics

Name: Magnetostrictive linear position sensors for industrial hydraulics
SKU: 66099
Availability: InStock

Available in: 27 versions

The most important application for our BTL magnetostrictive linear position sensors in rod design is in hydraulic drive units. They are exceptionally well-suited for use in hydraulic cylinders for position feedback, for molding and rolling mills, or for elevator and hoisting technology.

Since the sensors are installed in the pressure area of hydraulic cylinders, they have to have the same pressure resistance as the cylinder itself. The measurement element is installed in a pressure-rated tube made of non-magnetic stainless steel. The flange seals the high pressure area using an O-ring. Moreover, the electronics are integrated in a protective housing outside of the cylinder on the flange of the rod.

Features

High resolution of up to 1 µm
Measuring lengths of up to 7620 mm
Measures several positions and speeds at the same time
Programmable output signals – invert, configure, and document the measurement range
Flexible installation thanks to various thread types
Non-contacting, thus free from wear – no downtimes and a long service life
Expanded measuring possibilities with multi-magnet technology
Easy integration with equipment through a variety of interfaces – such as IO-Link, Profinet, EtherCAT, SSI, and analog
