CLVDT DiagramC-LVDT Air-Bearing Construction

The air-bearing of the C-LVDT is the key to providing incredibly high-resolution contact measurements.

A porous carbon bearing flows air around the probe’s plunger. The air cushion provides friction-free movement and radial stiffness that minimizes side-loading effects when scanning a moving target.

Diamond Tips

Each Lion Precision C-LVDT comes complete with an interchangeable diamond tip. The high-precision measurements performed by the C-LVDT demand the highest quality contact interface.

Diamond is Superior to Ruby:

Low Friction– Side forces cause less lateral deflection from moving targets and less hysteresis on direction reversal.

Highly Polished Surface– Diamond accepts and holds a high polish, minimizing the possibility of scratching the measured surface.

Minimal Wear– Increased accuracy and longer life.
