HR Series LVDT

Description: 

The HR Series general purpose LVDTs provide the optimum performance required for a majority of applications. The large 1/16 inch [1.6mm] bore-to-core radial clearance provides for ample installation misalignments and therefore reduces the application costs. Featuring a high output voltage and a broad operating frequency range, these versatile and highly reliable LVDTs deliver worry-free and precise position measurements.

Features:

  • 0.25% linearity (100% stroke)
  • Large 1/16″ core-to-bore clearance
  • Shock and vibration tolerant
  • Electromagnetic/electrostatic shielding
  • Calibration certificate supplied with each unit
