Fields of application
Capacitive limit level sensor Capanivo® CN 4020 is designed for full, demand and empty detection of bulk materials (DK from 1.6) in storage and process vessels. The probe made of glass fiber reinforced PPS plastic meets FDA requirements, making it suitable for the food industry. Active Shield technology ensures accuracy without the influence of material accumulation.
