Capacitive

Non-contact sensing with precision

Capacitive sensing technology measures changes in an electrical field caused by the presence, proximity, or movement of a medium. Because there is no mechanical contact with the measured medium, capacitive sensors are inherently resistant to wear and well-suited for detecting liquids, solids, and interfaces in challenging environments.

Key Benefits

  • No vessel penetration required
  • No moving parts — zero wear
  • Point and continuous measurement modes
  • Compatible with disposable vessels
  • Sensitive to small dielectric changes
