Component Specifications

Definition
A waveguide sensing element is a critical component in magnetostrictive position transducers that enables non-contact, high-precision linear position measurement. It consists of a specially designed waveguide tube that interacts with a position magnet to generate torsional stress waves, which are then detected to determine exact position with micron-level accuracy.
Working Principle
Operates on magnetostrictive principle where a current pulse sent through the waveguide interacts with a position magnet's magnetic field, generating a torsional stress wave that travels along the waveguide. The time difference between pulse transmission and wave detection determines position with high accuracy.
Materials
Typically made from ferromagnetic nickel-iron alloys (e.g., Ni-Fe 36-64) with precise metallurgical properties, stainless steel housing, and protective coatings for corrosion resistance in industrial environments.
Technical Parameters
  • Accuracy ±0.01% of full scale
  • Resolution 1 μm
  • Output Signal Analog (0-10V, 4-20mA) or digital (SSI, CANopen, Profibus)
  • Repeatability ±0.001%
  • Response Time < 1 ms
  • Protection Class IP67/IP69K
  • Maximum Stroke Length Up to 7500 mm
  • Operating Temperature -40°C to +85°C
Standards
ISO 13849-1, IEC 61508, DIN EN 60529
