PCE-MWM 500 VHF-Band Sensor / continuous moisture measurement in bulk (tank / silos)
Designed specifically for use in humidity measurement of high conductivity bulk materials, this moisture sensor is installed in bins, silos, troughs, bunkers case, distributors, augers and conveyors. Material in bulk or flowing mass, such as high iron materials, high ferrous powders, high conductivity ores, fly ash (mineral) ... is continuously measurable.
Also
in this humidity sensor, the
measuring principle is based on the use
of waves in the VHF
range. The
unit used for measuring moisture consists
of an electronic box and the moisture sensor
itself. The
sensor part is
manufactured of AISI 321 stainless
steel (tube diameter 15 ... 30mm).

Please note that we will need further information to provide a final price for supply and fit. We will need to know what materials are to be measured, we will need samples of the material, and we will need a technical drawing showing where the sensor is to be installed.
