displacement transducer - DI Series Magtrol's line of Displacement Transducers provide contactless measurement of absolute piston position in hydraulic and pneumatic cylinders and other applications. Their robust construction, large insensitivity to shocks and very long life (due to no moving parts and therefore no wear of components) make them both cost effective and very reliable. Magtrol transducers offer a wide range of operational temperatures and admissible pressure resistance for even the most demanding applications.

The transducer provides a direct 4-20 mA output signal corresponding to the measuring range, as well as VDC temperature output. As an option Magtrol offers the CST 113 Signal Converter, which allows the complete chain to be calibrated according to the specific needs, either in current or voltage output.

Features
  • Large measuring range: Piston displacements from 50 to 1000 mm; 80 to 250 mm for DI 63X models
  • Current-based output signal (4 to 20 mA) for displacement
  • Built-in temperature measurement
  • Very long life: No moving parts and therefore no wear of components (Eddy-current principle)
  • Slim measuring system allowing large measuring range
  • Insensitive to metallic impurities in the working fluid
  • High shock and vibration resistance
  • Capable of withstanding pressures up to 450 bar
  • Robust construction, designed for permanent operation in hydraulic systems
  • EMC susceptibility conforms to European standards
