Rotaries are a common point level indicator used for high-, mid- and low-level material detection in bins, tanks, and silos. Rotaries are wired to a horn, alarm or light panel to send an alert when material reaches the desired level. BinMaster's standard and fail-safe rotaries can be fit with a wide assortment of paddles and mounting plates, plus a compact mini-rotary is offered for constrained spaces. Extended rotaries for top mounting applications for high level detection, extensions for side mounting through thick bin walls, and stainless steel process connections for corrosive material ensure BinMaster has the right rotary for challenging applications.

Standard Rotary Level Indicator

Model: BMRX

The BMRX rotary paddle bin level indicator alerts operators when bins are full without the rigors and risks associated with climbing and continuously checking bin levels.

Fail-Safe Rotary Level Indicator

Model: MAXIMA+

The MAXIMA+ is BinMaster’s most advanced rotary level indicator featuring a complete fail-safe system that alerts to the loss of power, failure of the motor, or failure of the electronics.


Model: MR

The economical and compact mini-rotary is designed for controlling material levels in smaller bins and hoppers where other types of equipment simply won't fit.

Quick Disconnect

Quick Disconnect is specially designed to replace hard wiring, making it quick, easy, and affordable to install and remove sensors for cleaning, maintenance, repair, or replacement.

Vertical Rotary for High Level Detection

Vertical rotary extensions allow users to set top-mounted roataries to specific headroom requirement up to 144 inches.

Horizontal Rotary Extension for Thick Bin Walls

The horizontal rotary extension allows users to install a rotary on the side of a bin wall, such as those in concrete silos, up to 12” thick.

Stainless Steel Process Connection for Corrosive Materials

BinMaster’s optional stainless steel process connection—for BMRX or MAXIMA+ rotaries—features a fully stainless steel design to work in corrosive applications. 

Heat Tubes for High Temperature Applications

This optional heat tube is used to distance a rotary unit's electronics away from a heat source when the external temperature outside the bin exceeds 140°F (60°C).

Point Level Alarm Panel

Consolidating information at a convenient centralized location, the point level alarm panel is capable of monitoring and alerting to high and low status for two to 12 separate vessels. 

Flexible Rotary Extension for Lump Materials

A flexible rotary shaft extension is used to detect high levels in bins containing rock, aggregates, coal, ores, or other lump materials. 

Collapsible Rotary Paddle

Single and double-blade collapsible rotary paddles offer a unique solution that allows installation without the need to enter a bin. 

Adjustable Top Mount Rotary

The adjustable top mount rotary features an adjustable coupling that can be moved up and down the length of the shaft to accommodate differing materials levels in the bin or silo.
