PCE-MWM 210 VHF band sensor / continuous moisture measurement in concrete
(container / mixer)

For industrial continuous production of concrete,in-line moisture measurement for monitoring and controlling the mixing process is important. Consistent quality of every concrete batch, reduction of the consumption of cement, and shortest possible mixing times are the criteriawhich are important in concrete production. Sensors of PCE Instruments help meet those criteriathroughhighly accurate moisture measurement.

The production of concrete is subject to, e.g. large fluctuations caused by varying moisture contents of the raw and auxiliary materials (sands, aggregates). A reduction of these moisture fluctuations during storage is possible, but not easy to implement. Therefore, it makes more senseto do continuous online / inline moisture measurement during the mixing process to determine the respective componenthumidities or sand moisture. Subsequently, the dosage of water is controlled. This procedure not only allows the equalization of the quality of each batch of concrete but also reduces the mixing time.


Feuchtesensor

PCE Instruments planar sensors are at a suitable point in the ground or screwed in the wall of the concrete mixer (e.g.pan mixer, screw mixer). It can also be used when othervariants or types are used, e.g. for in-line moisture measurement of additives (case hopper for sand).

In combination with a control system (DCS) or a concrete moisture measurement sensor control & control unit of PCE Instruments, this is a true control of a sensor for measuring humidity.

An integrated temperature sensor continuously measures the temperature of the concrete (The readings are displayed. These are used internally for temperature compensation).
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.
