Redundant magnetostrictive linear position sensors

Magnetostrictive sensors

Available in:

16 versions

Our multi-redundant magnetostrictive linear position sensors meet the highest requirements for security and availability, even in difficult environments, such as when used in safety-related valves and hydraulic cylinders. They offer up to three independent measurement systems in the same housing and ensure increased operational safety thanks to various interfaces with diverse redundancies.

Features

  • Double- or triple-redundancy design
  • Temperature range of -40 to +85 °C
  • Analog and digital interfaces
  • Flexibly adjustable measurement range and signal inversion via software
  • Settings can be copied to all three measurement channels
  • Durable thanks to robust mechanical construction
  • Non-contacting and thus free from wear
