Product Description

The market for capacitive level sensor is highly competitive with many different brands offering their own level sensors based on the capacitance principle. The NivoCap-CK capacitive level switch by Nivelco, distinguishes itself from the competition through a solid build quality, reliable performance and an impressive list of features. Nivelco’s capacitive level sensor operates in the radio frequency range, which inherently delivers a high immunity for build-ups, making this capacitive level switch suitable for sticky materials other sensors may struggle to reliably read.

The smart electronics in Nivelco’s capacitive level sensor continuously evaluate the capacitance of the initial probe with the reference section. This value is compared with the value capacitance value between the reference probe and the housing. When material reaches the initial probe, the capacitance value will increase. This method results in minimal false alarms. Calibration is simple and can be done without opening the housing to ensure compliance with the Ex certification.

Suitable Applications for Capacitive Sensors:

  • Reliable point level detection of solids and liquids
  • Applications prone to false alarms due to build-ups
  • For bulk goods with a relative dielectric constant er ≥ 1.5 and liquids
  • Agriculture
  • Construction materials
  • Chemical and pharmaceutical industry
  • Food and beverage industry
  • Aggregates and mining
  • Power generation
  • Paper industry
  • Plastic industry
