BinMaster announces an innovative, patent-pending tilt switch used for high level detection of powders and bulk solids. The new BM-TSM tilt switch features a non-powered, pendulum-type design for fixed mounting on the outside on the top of the bin. It operates using a unique method to sense the probe tilt angle which activates a contact closure that can be used for a direct input to a control system, or activate an external alarm. The switch is activated when material rises and tilts the switching mechanism 15 degrees.
