High-level detector has mercury-free tilt switch
The patent-pending BM-TSM tilt switch (photo) used for high-level detection of powders and bulk solids mounts on the top of bins and activates an alarm when material rises and tilts the switching mechanism by 15 deg. The shaft of the tilt switch can be custom made in lengths from 1 to 8 ft, to accommodate site-specific needs. It is available with either a paddle or sphere mount at the end of the shaft, and can be used with materials that have a bulk density of at least 15 lb/ft3. Its simple mechanical design can be used as an alternative to a top-mounted rotary level indicator, and it is suitable for a wide range of solid materials in many industries, says the manufacturer. It can be installed through a 1.24-in. NPT process connection on the roof of the bin and sends an alert status to a horn, light or control panel.— BinMaster, Div. of Garner Industries, Lincoln, Neb.
