Silo Monitoring

4B has a wide range of level indicators for point level indication of bulk granular solids or powders in bins and silos.

All of 4B's sensors can be connected to our hazard monitoring systems.

Auto-Set

4B Autoset Radio-Frequency Level Indicator
Auto-Set

The Auto-Set series RF capacitance point level monitors are used for detecting high, intermediate, or low levels of liquids, powders and free flowing granular solids stored in tanks, bins, silos or other containers.

The Auto-Set series incorporates simple push-button calibration with microprocessor enable/disable switch for total protection of stored values. Once the Auto-Set is calibrated for the application it never has to be re-calibrated. Data is stored in non-volatile memory so it is not affected by power loss. A four digit LED display shows set values for uncovered, covered and trip settings, allowing simple set-up and adjustment. A set of voltage-free changeover relay contacts are actuated when the level of the material in the container reaches the probe. The unit incorporates a unique power shield which automatically compensates for material build-up around the probe and on the sides of the container, preventing false indication. The solid state electronics are housed in a weatherproof, flame retardant, glass-reinforced nylon enclosure. The Auto-Set is top or side mountable with 316 stainless steel probes lengths up to 10m long.

RLI

RLI  rotary level indicator
RLI

The RLI rotary paddle switch is designed to detect high and low levels of bulk granular solids in bins, tanks, silos, and as blockage detectors in spouts. The detection of material is achieved by a rotating paddle. If material impedes the rotation of the paddle, the motor topples of its axis and triggers a contact. The power supply to the motor is cut and the contact signals that a critical level has been reached, which will cause the motor for any inlet or outlet to close down or start up. When the level of the material reaches normal levels again, the motor returns to its initial position and restarts.

RLI Shaker

RLI Shaker rotary level indicator
RLI Shaker

The RLI “SHAKER” rotary paddle switch is used to detect high and low levels of bulk granular solids in bins, tanks and silos. It can also be used to detect plug conditions in spouts, where long life and fail-safe detection is required.

Utilizing a unique stepper motor drive, the RLI “SHAKER” rotates clockwise, then counter-clockwise and then shakes to shed any excess material build up. If the paddle rotation is impeded at any time by the bulk material then the electronic circuit provides a signal for level indication or control. The RLI “SHAKER” uses fewer mechanical parts compared with standard rotary level indicators. No gearbox or clutch is required as the stepper motor drive is directly coupled to the output shaft and is practically indestructible and cannot be damaged by forced or backwards rotation. Also, an adjustable torque control allows one unit to cover many different densities of material, and provides easy on site calibration without having to change paddles.

T500 Elite système de surveillance pour élévateurs à godets et convoyeurs
T500 Elite Hotbus™

The T500 Elite Hotbus™ is a serial communications system designed to monitor up to 256 sensors for combined belt alignment, belt speed, continuous bearing temperature, pulley alignment, level indication (bin / silo) and plug conditions on bucket elevators and conveyors. With automatic machine shutdown capability and PLC / PC compatibility, this advanced microprocessor based system offers low cost installation, versatility and easy system expansion. Logging and trending software is also available for historic data analysis and preventative or predictive machine maintenance.

HazardMon.com® is a secure cloud based hazard monitoring solution providing status notifications and data logging for bucket elevators and conveyors. Live system status, graphs and historical data can be viewed on any web-enabled device (smartphone, tablet PC, desktop or laptop computer). Emails can be sent to notify users whenever a change in the system's health is detected. An automated maintenance feature allows site operators to verify that all sensors on the system are operational and working correctly.
