The BRMX rotary paddle bin level indicator provides reliable point level detection and measurement of dry bulk solids in bins, tanks, silos, hoppers and conveyors for materials including grain, feed, plastic pellets, cement and aggregates. Mounted on the top or side of a bin, the BinMaster BMRX alerts operators when bins are full without the rigors and risks associated with climbing and continuously checking bins levels. When material is not in contact with the paddle, the paddle rotates freely. When the paddle comes into contact with dry bulk material, the paddle stops rotating and sends a signal – normally through the use of a horn or light – to alert that the bin is full.
The BinMaster BMRX features “de-energized” operation of the motor which shuts the motor down when materials is present, versus competitive rotaries which put the motor in a "stalled" condition. Power is not consumed until the bin is emptied and the drive shaft again begins to rotate – which saves on energy costs and prolongs motor life. It offers a fail-safe alert providing notification when power to the unit is lost. The BMRX rotary design includes a screw-top enclosure for easy access to motorized parts. It is CE approved and is appropriate for use in hazardous conditions when explosion proof protection is needed – featuring Class I, Groups C and D, Class II E, F, and G listings.
BinMaster also offers the Maxima+, an advanced rotary level indicator that offers genuine fail-safe protection via an LED indicator that alerts to the failure of power, the motor or electronics. For smaller bins and hoppers, the Mini-Rotary is an economical, compact rotary level control.

BinMaster vibrating rods feature a unique single-rod probe design with a sword-shaped blade that prevents bridging of material, making them superior to typical “tuning fork” designs by allowing material to easily flow by, preventing build up on the blade. Features include a self-cleaning sensor, switch selectable high/low fail-safe, and an auto sensing power supply which can accommodate 20 – 250 volts AC/DC. They feature three sensitivity adjustments – high for light and fluffy materials, medium, and low for heavier materials or materials that may tend to cling to the vibrating rod. They are easy to install, mounting to the vessel via a standard 1-1/2 inch NPT mounting socket and require no calibration. Remote electronics via a point level alarm panel are available to alert to bin levels for four up to 24 individual sensors.
The VR-21 is BinMaster’s standard piezoelectric driven vibration type point level switch, which has an insertion length of 7.37 inches. It is suitable for both top and side mount applications and is ideal for a wide variety of dry and bulk powder materials including extremely light, fluffy materials. The VR-41 is designed for use with a variety of heavy, medium and light materials ... including extremely light, fluffy materials. Intended for top mount locations, it is available in lengths from 13 inches up to 13 feet. The VR-51 extended vibrating rod uses a steel-rope reinforced cable and allows for insertion lengths from 19 inches up to 19 feet and is intended for top mount applications.

VEGASWING:
Versatile use in liquids
The piezo drive is the heart of VEGASWING, actuating the tuning fork on its resonance frequency. The frequency of the fork falls when being immersed. The frequency change is processed by the integrated oscillator and converted into a switching command. The piezo drive is screwed to ensure reliability and ruggedness. With the tuning fork of only 40 mm length, VEGASWING 60 works reliably in all liquids and mounting locations. Pressure, temperature, foam and bubbles and even viscosity do not affect the switching accuracy. Even pipelines with a nominal width of DN 25 are no problem.
VEGASWING 60 is the universal level switch for all applications.
Advantages
- Virtually independent of product characteristics
- Level detection up to +250°C
- Short tuning fork of 40 mm
Applications
- Level detection of liquids

The vibrating rod of VEGAVIB is actuated via piezoceramic elements. If the vibrating rod is immersed, the amplitude will be damped. The amplitude change is processed by the integrated oscillator and converted into a switching command. Due to the rod design, it is nearly impossible for material, e.g. granules, to get wedged in. Typical applications are overfill or dry run protection systems, e.g. in flour, milk powder, sand, cement, plastic granules, styrofoam and down feathers. Even products with a specific gravity up to 0.015 g/cm³ (15 g/l) can be measured. An adjustment with medium is not necessary as the mounting location and the granulation size do not affect the measurement.
Advantages
- Virtually independent of product characteristics
- Optimum rod configuration for solids
- Easy cleaning
Applications
- Level detection of solids

These are used for the maximum and minimum level in silos
and mill hopper which contain powder or grain material
which can be cereals, plastic material, sand etc.
In the “RL-A” series the paddle turns at low speed which
when in contact with material stops turning causing a contact
to switch.
In the “SM 85” series the functioning is caused by material
pressing on a rubber membrane which causes a micro switch
positioned internally to operate.

SITRANS LPS200 is a rotary paddle switch for point level detection
in bulk solids. The paddle switch technology detects full, empty or demand
conditions on materials such as grain, feed, cement, plastic
granulate and wood chips. The paddle switch can handle bulk
densities as low as 15 g/l (2.19 lb/ft3) with the optional hinged
vane or 100 g/l (6.25 lb/ft3) with the standard measuring vane.
A low revolution geared motor with slip clutch drives a rotating
measuring vane which senses the presence of material at the
mounted level of the LPS200. As material comes into contact
with the rotating paddle, rotation stops, which changes the microswitch
state. When the paddle is no longer covered by material,
rotation resumes and the relay reverts to its normal condition.

The tuning fork is piezoelectrically energized and vibrates at its mechanical resonance frequency. (of approx. 1200 Hz.) The piezos are fixed mechanically and therefore are not subject to temperature shock limitations. The frequency changes when the tuning fork is covered by the medium. This change is detected by the integrated oscillator and converted into a switching command.

DRO level detector
It is used to detect the level of any bulk products in all kind of industries thanks to numerous accessories, a robust casing and its easy mounting 2 wiring.
A gear motor drives the paddle rotation. When the product reaches the paddle, it makes a resistance couple which is detected. A dry contact is then activated and the power supply of the gear motor is turned off in order to preserve it. When the level of the product goes down, the resistant couple is equal to zero; the blade starts its rotation.

The rod is permanently excited by 2 piezo-electric oscillators. The mechanical oscillations are converted into an electrical signal used as a reference. When the product reaches the rod, the mechanical vibration stops and leads to a variation in the potential of the oscillating crystal and the switching of the signal relay.
