PCE-MWM 230 VHF-Band Moisture Measurement Sensor Crushed Stone, Gravel, Ore (conveyor)

A vast majority of materials contain moisture, which can be sometimes not to detect visually. To avoid mistakes in the production and to improve the quality it is necessary to take into consideration how much moisture any of the materials under control contains.
When it goes about liquids and bulk materials the right choice is the dielectric moisture meter PCE-MWM 230. Generally speaking there are a few models of the moisture meter which are meant for measuring of some particular materials and that is why that device a very wide application (mining and petrochemical industry, production of building materials, agriculture). There is no need in calibration in advance, as the principle of the device is based on the direct method of permittivity measurement. The measurements can be carried out not only for homogeneous materials but also for materials with fractions (crushed stone, gravel, ore etc). The device is non-nuclear, which is a big advantage.
For the enterprises dealing with the carbonated concrete rubble the device is irreplaceable. The level of moisture can reach the mark of 8%, almost equal to sand. The general description of the moisture meter structure is the following: an electronic unit and a probe-sensor made of stainless steel.


moisture sensor crushed stone


As it has been mentioned above the moisture meter is capable of measuring moisture in many materials, both homogeneous and heterogeneous, petrol and fuel, large-granulated bulk materials, agricultural products and crops etc. It is possible due the use of the very high frequency waves. This wavelength range makes the moisture meter a VHF band radio device. Moisture meter covers the whole volume of the material (even when there are big fractions) averaging the result of the measurements
It looks pretty simple-constructed, having a probe and two pins. The device can be mounted even on the wall of the reservoir or tank due to the cylindrical housing with G1 1/2" thread.
It can also be installed on the tube in the hopper as the coupling with thread G1" is directly at the top of the housing. As a result the probe will be over the hopper outlet.
The device is resistant to corrosion (stainless steel and dielectric materials) and can operate in the conditions deviating from the norm, for example, at temperatures of 145°C. The moisture meter probe can be mounted on the walls in the hoppers, in pipelines or on trays in conveyors. Due to pluggable design this version of the moisture meter can also be used for soil moisture control.
