Description
Overview
Capacitive sensor systems operating on the capacitive measuring principle determine the dielectric constant (DK) as a function of moisture. Many solids have a DK ≈ 5 while water has a DK ≈ 80, making this method particularly suitable for water detection in bulk materials and process equipment.
Versions / Applications
Multiple versions cover a broad range of industrial installations. Sensor geometries and materials are selected according to mounting and measurement requirements for conveyor belts, containers, storage bins and mixers.
SC 7100 — Wedge-shaped
Wedge-shaped sensor for installation on conveyor belts. Sensor heads can be supplied in Teflon, wear-resistant plastics or full-ceramics depending on material and application. Information brochure available.
SC 7200 — Bar-shaped
Bar-shaped sensor for installation in containers and storage bins. Lengths are available from 400 mm to 2300 mm depending on container size. Protective sheath options: Teflon or glass-fibre reinforced Teflon. Information brochure available.
SC 7800 — Circular
Circular sensor for installation in mixers and similar equipment. With appropriate mounting parts the sensor is installed in the bottom or walls of mixing and processing plants. Information brochure available.
