How does the capacitive measuring principle work?
The function of a moisture sensors using a capacitive measuring principle is explained. There are plenty of different measuring methods to determine the residual moisture of material such as bulk solids. Now we are focusing on the capacitive functional principle. Inter alia it finds its use in in-line moisture measurement (directly integrated within a working process). It can be classified into two methods of moisture measurement, direct and indirect. Direct measurement Direct measuring procedures are e.g. the Karl-Fischer-Tritation or drying out material (loss of water by using a drying cabinet, probably the most often used method). Indirect measurement Moisture sensors and systems belong to the indirect moisture measuring techniques as they allow conclusion concerning the water content by using for example the capacitive moisture measuring principle. Further possible measurements work with microwave, infrared or conductance methods. The main criteria is that these procedures do not detect the residual moisture of the bulk solids directly. Rather

Nivobob® - electromechanical bobsystem
Simply reliable. Simple installation and set-up Multifunctional unit for discontinuous level monitoring in bulk goods The electromechanical measurement device is an invaluable instrument in the field of inventory management due to its advanced electronics technology. The reliable electromechanical lot system Nivobob® with its robust mechanical design has for that reason become the choice of many plant operators across the globe faced with demanding conditions. The Nivobob® series of plumb bob sensors is used for continuous level measurement within bulk storage silos and also for interface measurement. The simple electromechanical measurement principle is a truly reliable all-rounder in most bulk materials. The sensor weight, made of a suitable material, attached to either a tape or rope is electromechanically lowered from the top into the vessel. Once the sensor weight rests on the material, the winding direction of the motor changes and the sensor weight is rewound to the upper stop position. The electromechanical

DispoDipper Sampling and transport in one device
DispoDipper
Sampling and transport in one device The new Bürkle DispoDipper is a sampling tube manufactured in a clean room specially designed for disposable use. Due to the blue colour, it is also perfect for use in the food, animal feed and pharmaceutical industries. The scaled sample container can be used for an exact measurement and it shows contents up to 50 ml or 1.5 oz. After sampling, the container can be closed and is leakproof. The sampling tube is suitable for 2” drum openings and therefore can be used for sampling barrels, canisters and other containers. The closed handle design ensures secure handling and prevents the dipper slipping out of your hand. DispoDipper is completely manufactured in one piece and can be used for sampling and subsequent transport of the sample in one device. In this way, cross-contamination or sample impurities are almost impossible. For sampling, first detach the cover at the predetermined breaking point from the handle. Afterwards extract the sample using the

Hygienic application for ACO moisture measuring systems ACO moisture measuring instruments: food industry and pharma industry
Hygienic application for ACO moisture measuring systems
ACO moisture measuring instruments: food industry and pharma industry ACO-Automation Components shows a hygienic solution for using their moisture measurement systems in the food and pharma industry. An ACO moisture measuring sensor determines the water content/residual moisture of bulk material through a food approval plastic plate. This installation kit has been specially developed for measuring bulk goods in screw conveyors. This method prevents a direct contact between the moisture measurement sensor and the bulk solids. https://www.acoweb.de/en/produkte

Fast and Easy Particle Size Measurement: 10 nm – 2100 µm! Now with a new optical design - simple operation – fully automatic measurement!
Fast and Easy Particle Size Measurement: 10 nm – 2100 µm!
Now with a new optical design - simple operation – fully automatic measurement! With the FRITSCH Laser Particle Sizers ANALYSETTE 22 NanoTec particle measurement becomes a simple matter, for professionals as well as for any employee – in production and quality control or in research and development. No prior knowledge is required. Just start the programme, select a SOP and add the sample – the rest takes place completely automatic. Fast. Reliable. Efficient. New optical design The very large measuring range of 0.01 µm up to 2100 µm of the ANALYSETTE 22 NanoTec results from the combination of two lasers with two different measuring cell detector spacings: Large particles are detected using an infrared laser with a large distance to the measuring cell, for small particles a green laser with a small distance to the cell is used, which permits the detection of the forward scattered light up to a scattering angle of 65°. The measurement of smallest particles down into the nano range is performed by the green laser light for backward scattering.

Measurement of particle shape and size with Image Analysis ANALYSETTE 28 ImageTec and ImageSizer!
Measurement of particle shape and size with Image Analysis
ANALYSETTE 28 ImageTec and ImageSizer! Both models of the Particle Sizer ANALYSETTE 28 ImageTec (wet measurement) und ImageSizer (dry measurement) are ideal for all applications where not only the particle size is measured but especially reliable statements about the particle shape are of importance. Via the optical analysis of particle shape and particle size, damaged particles, contaminates, agglomerates and oversized or undersized particles are identified accurately and fast, and can be viewed as single images. At the same time, the instrument offers a fast and efficient particle size measurement. The measuring time depending on the sample quantity, is under 5 minutes and the result is available immediately. This makes the ANALYSETTE 28 the perfect measuring instrument for the easy quality control, as well as for research and for laboratory tasks – and it is the fast alternative to sieving. Fast analysis of particle shape and size - Extra-wide measuring range, individually adjustable - High-performance

Controlling of the Gypsum production at E.ON “MPP3”  based on a moisture measuring system from ACO
Controlling of the Gypsum production at E.ON “MPP3”
based on a moisture measuring system from ACO E.ON „MPP3“ coal fired power plant in Rotterdam-Maasvlakte The “MPP3” is the most modern and biggest hard coal fired power plant with the notable gross power rating of net 1070 MW and a net efficiency of over 46%. The “MPP3” wants to reduce the effects on the environment as much as possible. One point to reach an environmental friendly process is the optimisation of the exhaust-desulphurisation unit. The desulphurisation is made by a wet flue gas cleaning unit controlled by a moisture measurement. This flue gas desulphurisation (FGD) is far more effective than in other traditional coal fired power plants. Beyond the “MPP3” can reach a biomass-combustion up to 30%. Of course the district heating is used from the adjacent companies. General description of the process The desulphurisation is based on burnt lime (CaO) thereby the end product gypsum (calciumsulfad-dihydrat) arises. For the analysis of the produced gypsum there is an in-house
