Introducing TRIME® Radar Technology

SONO probes and sensors deploy the exceptional TRIME® radar technology.


Cost effective and high performing measurement devices were the primary goals in the development of the new generation SONO moisture probes and sensors. The risk of non-acceptable products, due to malfunctioning devices or poor measurements, can cost dearly. Complicated calibration processes for individual recipes, laborious re-calibration after only short periods due to probe wear, incorrect added water quantities – all these factors cost time and money. Due to the innovative TRIME® radar technology, it is finally possible, to eliminate the disadvantages and problems of all previous moisture probes and sensors.

What is TRIME® TDR?

TRIME (Time domain Reflectometry with Intelligent MicroElements) is based on the TDR-technique (Time-Domain-Reflectometry), and was developed to measure the dielectric constant of a material. The metal rods, strips or plates are used as wave guides for the transmission of the TDR-signal. The TRIME-device generates a high-frequency-pulse (up to 1GHz) which propagates along the wave guides generating an electromagnetic field around the TRIME-probe. At the end of the wave guides, the pulse is reflected back to its source. The resulting transit time (10 ps..2ns) and dielectric constant are dependent on the moisture content of the material. IMKO has developed a patented measuring method. With this technology it is possible to measure the transit time with a resolution of 3 picoseconds! The moisture content is calculated inside the TRIME-device and is available at standard analogue outputs. A network interface on PC is also connectable via the RS232/V24 for processing the acquired data.

How is TRIME® TDR different?

Unlike the Capacitive, Microwave, Rsistance and transmittance methods, the TRIME® TDR method measuring field penetrates deep into the material. Therefore the TDR method shows less influence of heterogeneous moisture distribution in bulk materials or the nature of the sensor-to-sample-contact.

The TRIME-TDR-technique has an ideal measuring frequency between 600MHz and 1.2 GHz. The electromagnetic pulses generated in the TRIME device are high enough and constant for good resolution and accuracy of measurement. In addition, disturbing influences such as electrical conductivity have nearly no effect. These conditions
for precise moisture measurements exist in temperatures up to 266°F/130°C.

What else should I know about TRIME® TDR?

The general requirements made to material moisture measurement sensors are very demanding. The TDR method represents a contribution to greater customer satisfaction for quality and reliability. However, users should be aware of the respective limitations of the individual methods.
