Lenser Filtration GmbH visits IMKO in Ettlingen

LENSER Filtration GmbH presented the LENSER i-Plate, their first intelligent filter element, at IMKO premisses in Ettlingen. The material moisture in the filtration cake is determined by means of a moisture sensor during the process, which is unique.
Lenser has been researching this intelligent product since 2014 and has obtained support from a well-known sensor manufacturer. There were of course successful and less successful development phases in the various development stages of the sensor. Looking back, we can both proudly say: It was worth it! The LENSER i-Plate has been recognized with great interest in the market and has already been installed in some applications.
The show truck is an ideal way of conveying real and tangible information to the customer.
Many THANKS to the Lenser company for your visit and the technical information.

Are you interested, too? Contact us.

Press Release:
IMKO contributes to rebuild Notre Dame Cathedral in Paris

IMKO has been manufacturing moisture measurement technology for a wide variety of applications for over 36 years and is distribung worldwide. One of the applications is the measurement of moisture contents in masonry, bridges and monuments. This is done with high precision using the proprietary TRIME technology. This technology was originally developed in the 1980s to measure soil moisture.
As it is now known, the measurement technology is used in a project, managed through our French Distributor SDEC, based in Reignac sur Indre. This even takes a great extent in the reconstruction of the Notre Dame Cathedral in Paris. The company involved in the renovation needs the measured values in order to conclude on the building integrity of the damaged structure. The cathedral caught fire on the evening of April 15, 2019 and has been under reconstruction ever since.

“We are happy to be able to make an essential contribution to the reconstruction of Notre Dame”.

IMKO goes Green!

Climate change is a concern for all of us. IMKO is taking one step ahead towards local responsibility and global sustainability. We will convert our robust carrying cases to a novel material in 2021.
ARBOBLEND® from TECNARO has received multiple awards and has been awarded the Green Brand Germany. The material mix is based on glucose, natural waxes, minerals and natural fibers. The glucose obtained from sugar cane and sugar beet is technical sugar that does not compete with food. The new case consists of up to 93% renewable raw materials and is 100% recyclable.

Another advantage is that the carbon necessary for the
production of ARBOBLEND® is obtained from carbon sources in the atmosphere. Thermal recycling at a later date is then carbon-neutral in the sense of a closed carbon cycle

TRIME-GW Line – The largest sensor for measuring bulk solids with extremely low densities

The innovative GW Line single-rod probe is used to determine the material moisture in loose bulk materials with low density such as whole corn cobs, tobacco, medicinal herbs and aromatic plants, etc.
You all know what that means. Light bulk goods are often characterized by an inhomogeneous moisture content. This can be determined appropriately and with high precision using the TRIME-GW Line. The volume of the measuring field is approx. 12l and is particularly suitable for representative and reliable measurements of light bulk goods with inhomogeneous material moisture. The sensor uses our proprietary radar measurement technology (TRIME) and a special algorithm that scans the measurement volume several times per second and transfers the measurement signal to a downstream process control via the known standard interfaces.

Testing site Reutgraben

We are facing novel inquiries on our sensors every day, focusing on new applications for various tasks.
Therefore, with early 2020, we equipped a demo plot to be able to conduct long term testing of PICO32, PICO64 and T3PN in various conditions. The visualization of the acquired data has been maintained over the local ethernet (SQL database and RasperryPi) with a front end at the video screen in our lobby.

The data is corresponding to the geographical setting in the lower Rhine depression, characterized by light soil and a close groundwater table. The data show a high velocity of filling up and draining the rootzone with limits to the general ground water table over all applied probe types.

Everything you always wanted to know about roots

Using the PICO probes enables to read soil moisture and other data. Klaas Plaas (Managing Director of Berry Konsult, NL) states, that the use of PICO probes makes oneself a soil expert rapidly: Electrical conductivity, soil temperature and soil moisture are the three most prominent factors to draw conclusion on a root zone condition.
With IMKO this is possible, where you want to specifically have a look upon: roots of a crop plant.
Measurements in the drainage water or at the soil surface are only able give a very vague idea of root conditions.

„The nice thing of the EC-TRIME detection on electrical conductivity in soil is, that you see the conditions of the root zone instantly. Indirect measurements are only capable of displaying similar results after 2-4 days in deep field and greenhouse applications.”

IMKO presents the SONO M1 connect

The new SONO M1 has been realized in a sprint with a strong involvement of product scouts: distributors feedback reflecting different markets and applications. With this new product we are completing our product range effective immediate. Our probes are seriously exposed to load and wear on construction sites all over the world. The cable of the SONO M1 is now detachable right at the probe head with a MIL 7 coupling. So, in the unlikely event of cable damage just change the cable instead of changing the full probe set.
This is one of our core values: Realizing the best solution possible for our customers.

The seed has been sown, let us help you to optimize your harvest

Again an exciting harvest season lies in front of us. The moisture of corn, cereals or soy is an essential parameter to the quality and the yield itself. On the one side there is a huge potential to save energy, on the other side there is a high potential in yield management, due to not loosing weight on overdrying. In addition the elimination of the risk of underdrying helps to stabilize the yield and prevent a total loss, e.g. due to mould – an important fact to consider. Our DLG-proven TRIME©-GWs supplies the necessary parameter in real-time, just ask your dryer manufacturer , if they already use our technology, or directly get in touch with us.

Innovation based on our well-proven TRIME technology

Recently at IMKO, we came across the idea to extend our well-proven TRIME approach to determine the water content even in liquids. This is vital in fields where the amount of water content can influence the quality of liquids such as oil. Our preliminary tests were successful, and so we decided to set up a test platform in which we can measure, characterize and develop custom-made sensor prototypes. The test platform serves to validate any prototype sensor, which can be installed as an intermediate component (a pipe segment) integrated into the test platform. To further validate and improve the credibility of the sensor, we can now verify measuring the water content of different liquids under controllable parameters such as flow rate and pressure. The illustrated test platform was designed, constructed and placed into operation within half a year. Initial results show that we can achieve target sensitivity that is relevant in the industrial sector, e.g. to detect small amounts of water in oils. Despite being at the very beginning of our developments, we are excited to see that the huge potential in the IMKO TRIME technology is far from exhausted.

New process for us, better service for you

We improved our service and maintenance handling at IMKO. After a root analysis of the current processes, we were able to implement a series of changes. The before mentioned aims towards more transparency of the process for you. This requires automatization in order to keep you informed of the relevant steps of you repair or maintenance. We have launched internal testing of our new system and scheduled the live implementation for mid 2020.

We will keep you posted on the evolving process.

How to maintain the perfect installation for aggregate moisture probes

We recommend to have the SONO-VARIO installed under the silo hatch, which leads to obvious advantages:

  • The material flow is constant, therefore the material density remains constant during the acquisition of moisture readings
  • Moisture is determined, where batch samples would be / could be taken

Due to steady material flow and pressure on the sensor, the probe is kept clean. (A challenge is adhesive material, which would build up on the sensor and prevent correct readings of the goods flow).

Material Moisture Measurement within Filtration Technology
Filter presses are deployed for the liquid/solid separation of various different materials, such as ceramic material, sludge, tensides, oils, food products such as gelatine, fruit juices, grapes, and many others. One issue that has always been a problem at the filtration process was the capability to verify, respectively monitor the pressing process in a manner that generates constant feedback regarding the exact moisture content of the material currently being pressed, With the innovative SONO moisture sensors that features the extensive moisture measurement range of 0 to 100% and a conductivity range of up to 50dS/m, applications for virtually any material are possible.

The enterprise Scharfenberger Maschinenbau (production system engineering), one of the leading providers for the viticultural sector is deploying the innovative SONO-VARIO LD surface probe in its grape presses. The capability to exactly control the moisture content of the grapes during the pressing process ensures the ability to control the tannin content in the wine and consequently assure for the general quality of the wine.

Scharfenberger GmbH & Co. KG | D-67098 Bad Dürkheim

At the INTERVITIS INTERFRUCTA HORTITECHNICA 2018 trade fair, the company Scharfenberger Maschinenbau was awarded a prize. The expert jury awarded the measurement of residual moisture content  “HUMIDITY CONTROL” with a SILVER prize in the category „Processing and Process control”.
At the option “+ humidity control“, a special digital sensor precisely measures the residual moisture content in the drum of the press. The current actual value is displayed at the completion of every pressure stage on the touch display of the press control system and can subsequently be directly evaluated. Due to the intelligent pre-processing of the measurement values, the winemaker is able to exactly determine the residual moisture content at which the grape must is separated, or the pressing programme is stopped.
