Description

The OPTISWITCH 3200 is a vibration level switch with suspension cable for solid applications such as high level alarm on aggregate silos. The flexible suspension cable avoids mechanical strain caused by movements of the bulk solids. It is suitable for applications with a low density (e.g. aerosol) or for the detection of solids in water (e.g. in sedimentation tanks of hydro-electric power stations).
