Moisture in materials

Our main product in the segment of Moisture in materials is optical moisture sensor WCM411. It has a 4...20mA current output for process automation systems and an RS232 serial interface for maintenance and monitoring.

Water Content Monitor WCM411

Water content monitor WCM411 is an outstanding 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 silo feeders to detect moisture content in moving samples. A non-contacting remote measurement guarantees stable performance and long life time of the sensor.

Typical installations of WCM411.

Sensor installed at the aggregate silo feeder belt. WCM411 is inside the black hat of the protection tube.

Sensor installed under the sector hatch. This sensor is equipped with a heating unit.

The sensors are installed to measure the moisture content of the aggregate flowing from the vibratory feeders to the weighing scale.
