About rotaries What is a rotary? A rotary is used for point-level detection in powders and bulk solids with a bulk density of 2 pounds to over 100 pounds per cubic foot. It is used in bins, silos, chutes, and conveyors storing, moving, or processing powders, pellets, and granular materials. How Does it Work? The rotary turns a paddle continuously until it is stopped by material, then closes a relay to indicate a change in status. Rotary Alert Notifications Wire a rotary to a signal beacon, warning light, or audible horn to alert when a full or empty condition occurs. Alternatively, use a rotary...

Models for every measurement mission BMRX-300 with Status Light BinMaster’s BMRX-300 rotary level switch features true fail-safe operation and a built-in LED indicator light. The bright LED changes from green to red when the paddle stops turning when the bin is full or empty. BMRX-200 with Power Failure Protection The BMRX-200 includes relay outputs that are designed to be “fail safe” in case of power failure. If power fails to the rotary, the relays will default to the output deemed “safe” for a high-level or low-level indicator application. BMRX-100 with Mechanical Operation BinMaster’s standard...

Extended rotaries BinMaster extensions allow the rotary to adapt to tailored point level detection needs. Vertically oriented extensions measure further down into the bin to prevent overfilling or to protect valuable sensors at the top of the bin. Horizontal extensions enable mounting through thick bin sidewalls. Flexible Extensions A flexible 8 mm steel cable from 4” to 14’ long detects the level of heavy falling material when attached to a top-mounted rotary Vertical Extensions Get high-level alerts and specify headroom with a top-mounted rotary with a custom extension up to 144” Horizontal...

Rotary connections Aggressive, corrosive, or sanitary conditions require custom process connections. Get aluminum or stainless steel connections in 1-1/4” and 1-1/2” sizes with an internal 1.0” NPT option. Adjustable Couplings Vary the depth of a top-mounted rotary from 6” to 72” without entering the vessel using a sliding extension Heat Tubes Distance the electronics from the heat source when external temperatures exceed 140° F (60°C) with 6”, 8”, or 12” aluminum or stainless-steel extensions that can be side or top-mounted Tri-Clover Connections Stainless steel mounts, connections, and clean-in-place...

Mounting a rotary level indicator Side mounting or horizontal mounting Uses a solid shaft coupler and a half-coupling mounting plate, available in carbon steel or stainless steel. Plates available in 0°, 10°, 20°, and 30° angles use a flexible shaft coupler to absorb impact when loading and a full coupling mounting plate. Standard horizontal or vertical mounted mount Standard mounted rotary for vertical, horizontal and angled installations. Standard Extended Vertical Mount Standard mounted rotary for straight vertical installations. Angled mounting plates are available for sloped roof installations....

Choosing a rotary paddle Paddles BinMaster offers a wide selection of paddle for very light to heavy materials. Select paddles will collapse to fit through a 1.25” to 1.5” opening allowing installation without entering the vessel. For some applications, a direct connect paddle option will not require a coupler.
