Revolutionizing Concrete Quality with Precision Moisture Measurement

In construction, water-to-cement ratios dictate structural integrity. Our SONO sensors provide real-time, precise moisture measurements for aggregates, ensuring consistent concrete quality from the mixing plant to the job site.

Robust Sensing for All Aggregates and Environments

Our SONO sensors reliably measure the moisture content of gravel, sand, and grit up to 32 mm as well as other aggregates such as expanded clay. Calibration curves for all common aggregates are included as standard. Wear and abrasion have no influence on the measuring principle, meaning regular recalibration is not necessary. Specially hardened materials (available as an option) delay early wear on the sensor and significantly extend the service life, even in the most demanding industrial environments.

Seamless Integration Across Your Entire Workflow

The sensors are compatible with all common control systems and are characterized by simple commissioning and parameterization. We use the same technology with different sensor geometries for mobile measurements in sand and stones during delivery or storage as well as while dosing. This versatility ensures that whether you are managing inventory in the yard or precisely controlling the mix in the batching plant, you have a unified, high-performance data stream to rely on.

Precision Quality Control from Mix to Finish

On the job site, measurements of water content and w/c ratio—and even the moisture content in finished surfaces or existing buildings—are conducted quickly, precisely, and reliably. This enables teams to make, deliver, and maintain concrete with consistent, stunning quality and to provide complete documentation where required. By removing the guesswork from the equation, we make measuring efficient and reliable: ”#measure with pleasure.”

IMKO Optimizes Concrete Production with TDR Moisture Measurement
IMKO Micromodultechnik GmbH utilizes refined TRIME-TDR technology to ensure precise moisture measurement in sand, gravel, and fresh concrete, enabling adherence to strict recipe specifications. Innovative TDR Technology for the Construction Industry For over 40 years, IMKO has developed specialized sensors that surpass traditional measurement methods. The TRIME technology creates a defined measurement volume along the sensor, eliminating the need for recalibration due to surface abrasion. This ensures long-term accuracy and high reliability in demanding bulk solids environments. Advantages of the SONO sensor series: * Short measurement times for rapid process control * High resistance to mechanical wear and abrasion * Flexibility in mechanical integration with low material coverage * Reliable data for w/c ratio determination Quality Control from Material Delivery to Mixing Monitoring begins at the point of delivery. Mobile solutions allow for the immediate assessment of aggregates like sand and gravel before they enter the process. This ensures that recipe adjustments can be made in real-time, preventing costly mixing errors and maintaining project

New generation of moisture probes, for Food, Atex, and more
Increase your plant safety and save time and resources through innovative sensor technologies for food, chemical, pharmaceutical and other industries. All foodstuffs and bulk solids contain a proportion of water. The moisture content not only determines the quality of products, but also their shelf life and due to the weight, their price. Legal requirements lay down the framework. With material moisture measurement, you can determine the water content in your foodstuffs and bulk solids. IMKO is presenting a new generation of moisture probes in the form of its SONO probes. These were specifically developed for applications in food manufacturing and the construction industry, as well as the chemical and pharmaceutical industries, but can be used in other industries too. Not just superficial moisture What is special about the TRIME method is that the measuring volume of the probe completely penetrates the adjacent material. In this way, not only measured values for surface moisture are determined. In contrast, measured values for representative bulk volumes in the process are transparent. In addition, there is no

Fast and precise moisture measurement in screw conveyors
Representative conditions and decent material flowin order to actually measure the process and no artificial accumulations of material. In order to reliably measure in bulk solids, it is necessary to determine an installation spot maintaining representative conditions and a decent material flow in the measuring field in front of the probe in order to actually measure the process and no artificial accumulations of material. A favorable installation was realized when using a SONO-VARIO LD in Italy. The screw diameter is large enough to allow the 108 mm probe diameter to fit into the screw housing without restrictions in the geometry, causing dead ends of material flow. Typically, the probe of choice would be a SONO-MIX Mini LD or even the larger SONO-GS1, as their rectangular geometry qualifies for easier integration into existing layouts of screw conveyors and narrow threads.

Applications and advantages of TRIME technology
Since 2023, we have a dedicated ATEX product portfolio in the specification: ATEX Directive 2014/34/EU | Ex II 2 D Ex tb IIIC T75°C Db according to EPS 20 ATEX 1 237. What is special about the TRIME method is that the measuring volume of the probe completely penetrates the adjacent material. In this way, not only measured values for surface moisture are determined. In contrast, measured values for representative bulk volumes in the process are transparent. In addition, there is no need for complex and error-prone bypass designs when using our TRIME systems. Since the end of last year, we have a dedicated ATEX product portfolio in the specification: ATEX Directive 2014/34/EU | Ex II 2 D Ex tb IIIC T75°C Db according to EPS 20 ATEX 1 237. Advantages of TRIME technology * Grain moisture and product moisture measurement directly in the dryer * Inline measurement in the process at up to 130°C * Reduced working time and higher process transparency through continuous measurement * Cost savings, since time-consuming post-treatments in the event of over- or under-drying become superfluous * Measuring ranges up to 70% humidity *
