The Advantages of Range Spring/LVDT Technology For Level Measurement

One of the most trusted devices for continuous liquid level measurement remains the displacer level transmitter. This transmitter operates on the Archimedes principle of buoyancy, which holds that any object, wholly or partially immersed in a fluid, is buoyed up by a force equal to the weight of the fluid displaced by the object.LVDT technology

The two main technologies that are used as displacer level transmitters in the industry are torque tubes and range spring/LVDT (Linear Variable Differential Transformer) technologies. There are substantial technology advantages that can make using range spring/LVDT technology based displacer transmitters preferable to a torque tube based instrument. Magnetrol® has produced a new white paper comparing range spring/LVDT technology to torque tubes. In this white paper, you will be able to learn about both technologies extensively so you can make an informed choice:

  • See the significant differences in measurement accuracy
  • Investigate in-depth the structural integrity of the two technologies
  • View the installation footprints of torque tube and range spring/LVDT transmitters
  • Explore the maintenance considerations for these technologies
  • Compare the liquid level measurement transmitters point-by-point

More Information

More about the advantages of range spring/LVDT technology over torque tubes can be found in the new white paper, including information about the structural integrity, installation footprint and maintenance of both technologies.
