Moisture meter for drywall and other sheet materials on conveyors

December 5 2022 г.

FIZEPR-SW100.15.1 is a moisture meter designed for non-contact measurements of moisture content in drywall, fiberboard, chipboard, medium density fiberboard plates and other sheet materials on a conveyor line. This moisture meter can also be used to measure moisture content in timber.

The moisture meter sensor has an operating temperature of +180ºС, so it can be used in drying chambers.

Measurement of moisture in crude oil with a high gas volume content

October 18 2020 г.

For all existing crude oil moisture meters, the metering error increases when gas appears in oil. For most of them, when gas volume content exceeds 2 - 5%, the metering error becomes unacceptable.

A solution has been found specifically for FIZEPR-SW100 series in-line moisture meters to ensure accurate crude oil moisture measurement even with a high gas volume content. The solution is shown in the figure.

CONCENTRATION ANALYZERS FIZEPR-SW100 OF ACIDS, ALKALIS AND SALTS

March 15 2019 г.

The new series analyzers designed for measuring concentrations of salt, acid and alkali solutions is put into production. Analyzers can also be used as moisture meters, but they can also measure materials with high electrical conductivity, such as anthracite, sewage sludge, ion-exchange resins (ion-exchange polymer), etc. Analyzers are used for in-line control of materials as well as for measurements in tanks and laboratory studies.

Dear Sirs, I am interested in your products, especially in-line moisture meters to make "Measuring of burden raw material moisture on a conveyor" for agglomeration production. I would like to receive additional information on the possibilities of your sensors for solving this problem with approximate cost and equipment list. I am also interested in the ability to integrate your equipment with Siemens controllers.

Moisture meter FIZEPR-SW100.10.X for bulk materials

Reply:

According to operating principle, the device belongs to dielectric ones. As capacitive sensors, it measures permittivity of the substance and then determines the moisture using permittivity.

Unlike other dielectric devices, our instrument is also a radio device. It measures the absolute value of the permittivity. Moreover, not a narrow strip of material near the transmitter (ceramic plate) is analyzed, but a large amount of not less than 10 liters.

This is important since bulk material moisture typically is not uniform in volume. Also the moisture meter is used on lump materials with granular size up to 5 cm.

The device can be installed above the conveyor belt. However, there are changes of density (lumpiness) of bulk material and amount of air between the particles during belt movement. For any of moisture meter (except for optical) this leads to measurement errors.

Therefore if high accuracy is needed, we recommend to install the sensor in the hopper, dispenser, or at least in the tray in which the density of the material is more stable than on the conveyor belt.

Its output signals: digital MODBUS RTU and current 4-20 mA signals are simultaneously transmitted.

In your case of application to estimate the accuracy it is necessary to know the name of burden material and moisture measuring range.
