Methods for determining a material's moisture content |
||||||||||||||||||||||
| The capacitive moisture measurements has been a proven method to determine the material moisture for many years. The moisture is determined as a function of the relative permittivity. Moisture = f (εr) For a measurable capacity change in a moist material, the significantly higher relative permittivity of water as compared to other known substances is the decisive factor. Because of the large differences of the relative permittivity, already small amounts of water percentages in a material can be detected based on a change in capacity. We developed numerous designs which are frequently used in the building material, chemical, and foundry industry. The sensors are properly integrated into the product flow. Sensors of various sizes and designs are available. Special electronic measuring instruments evaluate the capacity changes and provide an analogue output signal depending on the moisture.

| Rod-shaped mounting probe SC-7200
|
||||||||||||||||||||||
| This probe was designed for installation in tanks and silos. As a standard, 5 sizes corresponding to the installation conditions are available. The protective jacket is made of Teflon to prevent caking. Two bar-type probes are installed to obtain a good averaging of the moisture. A measuring generator converts the material moisture into a signal 4 - 20mA. Technical data:
