SONO-Ex GS1 Humidity Sensor for Heterogeneous Bulk Materials

The SONO-Ex GS1 humidity probe consists of an aluminum housing with a PEEK window. The probe is connected to the electronics housing in which the TRIME TDR transmitter is located.

This generates a high-frequency TDR pulse with 1 GHz.

The TDR pulse travels along the waveguide of the probe and creates an electromagnetic field around the probe in the material. The transit time of this pulse is measured with a resolution of one picosecond (1 × 10^-12) to determine humidity and conductivity.

Applications

With the relatively large probe dimensions and the large measuring field, the SONO-Ex GS1 is ideally suited for heterogeneous bulk goods such as wood chips, pellets, pasta and similar materials.

The humidity probe is built into e.g. containers, material hoppers or screw conveyors.

Advantages

• The large measuring field with a volume of 5 liters ensures a representative and precise measurement of even coarser, inhomogeneous materials
• You can save up to 15 different, individual material calibration curves directly in the probe
• The probe configuration for different applications is self-explanatory and simple
• Signal processing and evaluation with intelligent filter algorithms are integrated in the probe
• Additional evaluation devices are not required
• Thanks to the radar technology and the disc-shaped radar scan, the measurement is extremely reliable
