Moisture sensors for the concrete industry The right moisture sensor for every application Moisture Sensor Experts

X Founded in 1984 as an engineering firm, IMKO GmbH has been working on moisture measurement for over 30 years now. X Based on the unique TRIME-TDR technology, IMKO experts developed sensors for science and meteorology in the early 90s. A few years later, the product range was extended with solutions for measuring moisture in grain, primarily for applications in the agricultural sector. X Si nce the introduction of the SONO series in 2010, IMKO GmbH now offers a product portfolio that enables moisture measurement in any material, even for detection of just a few drops of water in solids,...

IMKO – Application fields Bulk solids

The IMKO TRIME-TDR measurement method The sensors developed by IMKO are based on measurement with Time Domain Reflectometry, or TDR for short. In principle, this measurement method is suitable for a range of applications, such as cable break detection or even measurement of fill levels. When applied specifically for measuring moisture in bulk solids and liquids, the physical effect is used, which correlates the propagation speed of electromagnetic waves with the dielectric properties of the material to be measured. Since water has a significantly higher dielectric constant than the...

TDR measurement with the patented TRIME method Implementing a TDR measurement is usually associated with significant technical effort. Very accurate pulses must be generated and the measurement requires the utmost in precision. Therefore, for a long time, TDR technology remained a laboratory measurement method kept back for science. Measuring devices based on TDR were not only very expensive, but also large and unsuitable for field use. The TDR technology optimized by IMKO specifically for material moisture measurement, the TRIME method (Time Domain Reflectometry with Intelligent...

The SONO probe as a "moisture tomograph” The guided radar wave (in green) propagates at approximately the speed of light. The sensor measures the material layer by layer discoidally and transverse to the sensor surface, as is familiar from a computer tomograph, for example. This method results in a sensor with an exactly defined measurement field, which can measure without errors even in the event of fluctuating fines or varying grain size. By measuring transverse to the sensor surface, the mechanical condition of the sensor surface does not represent a disturbance variable, i.e. the...

SONO process moisture probes for the bulk solids industry Increase your plant safety and save time with resources as well as innovative sensor technologies All aggregates and bulk solids contain a proportion of water. In addition to the quality of the final product, moisture also determines the weight and the price. Legal requirements lay down the framework. With material moisture measurement, you can determine the water content in your aggregates and bulk solids. IMKO is presenting a new generation of moisture probes in the form of its SONO probes. These were specifically developed for...

Individual calibration based on your specific C materials is possible. xx ossibility of checking the agreed maximum moisture on delivery, in real time and without the need for P a laboratory. xx ggregates not measured in the process (in the...

Mobile moisture measuring probe for sand, gravel, crushed stone and other materials Complete HD2 measurement carrying case set with SONO-M1 The set comprises: • HD2 display unit • SONO-M1 moisture probe • AC adapter (12 V/2 A) • Travel plug adapter for various countries The accuracy of the measuring systems is 0.1-0.2%, while products from competitors only achieve 0.5%. "Manufacturers of mobile sand moisture measurement meters have previously failed to impress us. But the HD2 from IMKO has exceeded our expectations. After several days of comparison measurements in the laboratory, we can...

Online moisture measurement in sand and gravel 2 Processing raw materials to make concrete Guarantee quality, directly in the process and in real time xx and, gravel and crushed stone up to 32mm and other aggegates such as expanded clay can be measured reliably. S xx alibrations for all conventional aggregates are preinstalled but it is also possible to carry out individual C calibrations based on your specific materials. xx Simple commissioning with minimal calibration requirements. xx inimum maintenance and maximum reliability, as the TDR technology is characterized by long-term...

Conventional integration with simplified commissioning The technical integration of the SONO sensors is no different from other moisture measurement systems. The sensor is usually supplied via the system voltage and the measured value is sent to the controller via an analog signal. This means that the sensors can be integrated in the conventional way by your plant manufacturer. Commissioning and adjustment are comparably easy, as the TDR sensors do not have to be laboriously adjusted to multiple points on individual products. The sensors can be calibrated as usual, whether via the...
