OPTISWITCH 3200 is a vibrating level switch with suspension cable for solid applications such as overfill-protection of aggregate silos. The flexible suspension cable avoids mechanical strain caused by movements of the bulk solids. It is also suitable for plastics applications up to a density of <20 gr/l / <2.67 oz/gal US (e.g. Aerosile) or for solid detection in the water of sedimentation tanks at hydroecletric power stations.
OPTISWITCH 3300 is a vibrating level switch with tube extension for universal use in applications with bulk solids and powders. The robust device is designed to detect the min or max levels in abrasive as well as adhesive media and operates reliably even in solid applications with extremely low density. Its tube extension enables level detection in thick-walled vessels or for a more flexible position of the switching point, e.g. in mediums that form a cone of bulk goods.
