Full Description

The SMART III Radio Frequency Moisture Sensor employs a radio frequency (RF) power loss technique that operates at 2 Megahertz. The sensor projects an RF field into the sample and measures the loss or change in RF dielectric constant as affected by moisture. Thus, the System Response is a measure of the total water in the RF field, which is directly related to the moisture content of the material. The RF power loss absorption principle is a Finna Sensors patented feature. For high temperature environments up to 485°F (250°C), the high temperature RF sensor can detect product moisture inside a kiln or dryer. Its unique open frame construction minimizes dirt and contaminant accumulations.

SMART III RF Probe
The SMART III RF Probe connects to the SMART III RF / Oscillator Box, and is installed in chutes, silos, etc. for measuring powders or granular materials. System includes Oscillator Box and RF Probe Assembly with 8’ cables.  Probe lengths available from 6” to 48” (please specify in comments).  Touchscreen console is required (sold separately).
