Polarmoist is a new optical moisture sensor designed for detecting moisture content of concrete aggregates. The sensor embeds a micro-processor and uses LED’s as light sources. Moisture content is determined as percentage of water by weight of dry aggregate. The sensor is most optimal when used above conveyors or sailo feeders to detect moisture content in moving samples. A non-contacting remote measurement guarantees stable performance and long life time of the sensor.
