CAPTRON Compact Capacitive Level Sensors offer a proven, reliable and cost-efficient solution for measuring fill levels and limit levels in industrial applications. The sensors accurately detect liquids, bulk materials, pastes, adhesives and chemically aggressive media using a capacitive measuring principle.
With the CAPselect configuration system, each compact probe can be individually adapted to the application, container design and required sensor characteristics. CAPTRON manufactures probe lengths with millimeter precision, providing maximum flexibility and application-specific customization.
Users can freely combine electronics, process connections, probe rod types and probe lengths to create the optimal sensor configuration. Additional options include integrated temperature measurement, tank illumination and enhanced pressure resistance.
The robust design combines wear-free electronics with high-quality materials such as anodized aluminum, stainless steel, PTFE (Teflon) and PEEK, ensuring reliable operation and a long service life even under demanding industrial conditions.
Integrated temperature measurement of the medium, reducing the need for additional sensors.
Integrated high-power LED illumination for improved visibility inside tanks and containers.
Enhanced probe versions for applications requiring higher pressure capability.
