MOLOSmembran level indicator Level measurement in bulk solids for less money
MOLOSmembran level indicator
Level measurement in bulk solids for less money The maintenance free MOLOSmembran level indicators are an appropriate alternative for level control applications with dusty, powdery, or granulated bulk material. They are perfect suitable as jam indicator at drains of screw conveyors or feeders as well. The big advantage of these robust and very reliable measurement devices is that no power supply is necessary. Therefore the installation and operation of these level controllers is very simple and cost-efficient. You can get all of these quality products with ATEX approvals for use in gas and dust explosive hazardous areas. These point level sensors can be adjusted to the specific application with different housings and membranes.

Explosion protection with MOLOSroto from MOLLET  MOLOSroto rotary paddles avoid explosions even in very dusty environments!
Explosion protection with MOLOSroto from MOLLET
MOLOSroto rotary paddles avoid explosions even in very dusty environments! Even it is difficult to imagine, working in such an environment is life threatening. Dust is able to explode! The reasons for that are the increased reactivity and the lower thermal conductivity due to the large specific surface area. For example a fire ball with more than 15 m in diameter arises, if only 1.5 kg of pulverised lignite is detonated by a spark. But what might dust mean? Dust consists of smallest, finely divided solid particles of any shape, structure and density with a particle size of less than 0.5 mm that sediment due to the self-weight but although remain airborne as a dust/air mix for a time. MOLOSroto rotary paddles with the required approvals avoid explosions even in very dusty environments. The explosion protection required for that is achieved by the ignition protection category “t” and “c”. In order to provide the type of explosion protection “t“, the protection is based on the use of dust proofed and dust tight housings with a limitation

Explosion protection made by MOLLET Level measurement in explosive atmospheres requires know-how provided by MOLLET
Explosion protection made by MOLLET
Level measurement in explosive atmospheres requires know-how provided by MOLLET Before level measurement in a potentially explosive atmosphere could be operated the potential risk of explosion has to be evaluated in a risk assessment. Part of this is the evaluation of the formation of explosive atmospheres. This will occur only, if atmospheric oxygen in sufficient quantities, an effective ignition source and combustible material appear at the same place. Combustible material could be flammable dust, gas and hybrid mixtures. Flammable dust means dust, fibers or suspended particles which can burn or glow in the air and could explode in atmospheric conditions. Products like coal dust, aluminium powder, powdered sugar, wheat flour or dust caused by grain are included. These dusts occur permanently by transportation, filling and discharging of bulk solids and are often been spread over the entire premises. Depending on the danger of explosion the premises is classified into different potentially explosive atmospheres according to the ATEX guidelines.

MOLOSroto – Rotary paddle Reliable all-rounder for level measurement in bulk solids
MOLOSroto – Rotary paddle
Reliable all-rounder for level measurement in bulk solids The rotary paddle switches of the MOLOSroto series are the ideal solution for level monitoring in the areas of storage, processing and transportation. Fine powders of the pharmaceutical industry can be reliably measured as well as sand and coarse gravel for the building material industry or plastic granular or wood pellets. In order to match this extensive scope of tasks the MOLOSroto devices are provided in thirteen different basic versions. One of them is the MOLOSroto DF21 that is characterized by a wide range of applications. The MOLOSroto DF23 with reinforced blade shaft is even more robust than the DF21. Many other sensors require an additional protective roof within large silos, as significant forces impact on the sensors for empty detection. With the MOLOSroto DF25 it is a different story; the DF25 is equipped with an angled jib, a protection tube made of stainless steel, reinforcement rips and a solid flange; therefore it reliably monitors the empty level

MBA Instruments (MAIHAK) brings MBA808. Reliable level indicator and also pile bulldozer for bulk material.
MBA Instruments (MAIHAK) brings MBA808.
Reliable level indicator and also pile bulldozer for bulk material. MBA Instruments brings MBA808 on the market. This level indicator with patented step motor drive, ensures that the entire silo space is used and will give a full signal. The MBA 808 has two different functions: 1. Levelling the cone. 2. Level measurement. In the silo a slowly rotating paddle, with a maximum diameter of 2500mm, will planish the bulk from the inside to the outside. Therefore the edge area will be filled with bulk and the capacity of the silo increases. The signal switches, if the rotation of the shaft is blocked. Technical information about the MBA808 Power supply: Supply voltage: 24 V DC (± 10%) Power consumption: 30 W Full indicator: Signal output: 24V DC or dry contacts, support up to 30V 1.2A. Full indicator: the signal is activated when the axis of rotation is blocked. Switching behavior: The parameters speed, reaction time, switching speed and delay time are optimally matched to the application. Strength: adjustable up to 20

Customer request energy efficiency  Energy efficient level indicators for bulk solids applications
Customer request energy efficiency
Energy efficient level indicators for bulk solids applications The request of many customers to save energy in their production processes can be realized not only with high end sensors but although with level indicators that enable a reliable and price worthy level measurement without any power supply. The level indicators of the MOLOSmembran series of MOLLET exactly meet this requirement and are used from satisfied customers worldwide in the applications storage, transport and processing of bulk solids. The MOLOSmembran level indicators of MOLLET are mechanical switches for bulk solids with a bulk density from 0.3 to 2.5 g/m³. As soon as the bulk material reaches the sensor, the signal is switched by the pressure of the bulk material on the membrane. All components that are in contact with the product like mounting ring or membrane are available in a stainless steel version. In case this is not needed, cheaper materials like a Viton-membrane or mounting rings made of Zinc-plated steel can be ordered. The housings are alternatively

MOLOSroto Level indicator Universal level indicator for any bulk solids level measurement application
MOLOSroto Level indicator
Universal level indicator for any bulk solids level measurement application The MOLOSroto level indicator series consists of 12 different devices types that can be configurated with a lot of options and equipped with many accessories. This means that MOLLET Füllstandtechnik offers a unique diversity of rotary blade level indicators that are exactly adapted to the individual measurement task and turns them into a universal level measurement device for all kind of bulk solids. For example housing material, power supply, versions for process temperatures up to 500 °C or pressures up to 10 bar, a lot of process connections and blade shapes can be selected individual in the catalog. Of course all sensors can be ordered with ATEX approvals for the use in any kind of gas and dust explosive areas. For application with even higher requirements special devices are developed and offered. The shown customized MOLOSroto rotary paddle guarantees reliable measurement results for example in a test reactor with process temperatures above 1.200 °C. MOLOSroto
