Capanivo CN 7121 - Synthetic Capacitive Sensor

Brand: UWT GmbH

The Capanivo® CN 7121 Synthetic Capacitive Sensor is a highly adaptable, rugged capacitive level switch designed to offer precise point-level detection in diverse industrial contexts. By pairing robust mechanical construction with advanced electronic filtering, it capably handles moderate buildup, dust-laden atmospheres, and media with changing dielectric properties. Its integrated design, flexible mounting arrangements, and fail-safe features make it a valuable asset for plant engineers and operators seeking reliable, low-maintenance solutions.

When deployed and maintained correctly:

  • Overfill Incidents and Downtime are minimized, enhancing safety and preserving product integrity.
  • Installation Complexity is reduced by integrated electronics and versatile mounting options.
  • Operational Efficiency improves, as stable level detection prevents raw material shortages or improper batching.
  • Longevity is achieved through dust-sealed housings, robust probes, and simple calibration protocols.

By following best practices in installation, calibration, maintenance, and inspections, the CN 7121 can serve as a cornerstone of dependable level detection—helping plants sustain productivity, meet regulatory demands, and uphold stringent safety and quality standards for years to come.

Features
  • Easy integration in existing processes due to IO-Link technology
  • "Tip Sensitivity" and "Active Shield Technology" ensure reliable measurement results even with sticky or foaming media
  •  Wetted part made from PVDF for maximum chemical resistance
