LVDT sensor WLG

LVDT sensor for numerous industrial applications in production, inspection, quality assurance, test and laboratory. The LVDT sensor with a Case diameter of 12mm has a coil unit calibrated to 80mV/V with a fully symmetrical coil design according to the LVIT differential choke principle / half-bridge circuit. The proven design guarantees high temperature stability with very low temperature drift. Variants with different Carrier frequencies and increased temperature and dynamic ranges are available, as well as different connection versions.

Special versions with modified flange and connection dimensions according to customer requirements are possible.

Important features

  • Nominal stroke: 10 mm up to 500 mm
  • Mechanical stroke: 10 mm up to 258 mm
  • Case diameter: 12 mm
  • Operating temperature: -50 ... 80 °C, optional up to 120 °C
  • Protection class (DIN 40050): IP 64
