Point Level Indicators


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 standardand 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.

Capacitance Probes

A capacitance probe is a point level indicator, commonly used for high or low level detection in a bin, tank or silo. BinMaster capacitance probes offer fail-safe operation, “quick-set” calibration, plus interference-free operation–working far below the RF level of 9 KHz at just 6 KHz–so they will not interfere with two-way radios or other equipment operating in the radio spectrum.

Diaphragm Switch

A diaphragm—or pressure—switch works by activating a sensitive micro-switch when material reaches the level of the switch in the bin. It sends an alert that can be used to start or stop a process or alert to a high, medium or low-level in the vessel. Commonly used in grain, feed, seed or other granular material, BinMaster diaphragm switches are offered for either internal or external mounting can can be wired to a light, horn, alarm, or BinMaster point level alarm panel to indicate an alert status.


Tilt Switch

A tilt switch detects rising levels of powders and solids and activates an alert when the device is tilted to 15 degrees. It is commonly used for high level detection in silos, over conveyor belts, in open pits, or for plugged chute detection. These affordable level detectors are available for fixed or hanging mounting, with optional hazardous location approvals, and mercury-free compliance.

Vibrating Rod

Vibrating Rods—also know as vibrating level switch—are a reliable point level sensor used for high and low-level indication or plugged chute detection. They can be used in light, fluffy powders and flakes with bulk densities as low as 1.25 lb/ft3. BinMaster vibrating rods feature a unique, sword-shaped probe that resists buildup and false alarms. Special models detect sediment under water and a mini vibrating rod fits in tight spaces and small hoppers.
