Abstract

A method includes optically interacting a bulk material or powder stored in a storage bin with an integrated computational element (“ICE”) configured to modify an electromagnetic radiation according to a characteristic of the bulk material or powder. The method also includes detecting the modified electromagnetic radiation with a detector, and producing an output signal correlated to a value for the characteristic of the bulk material or powder, and receiving and processing the output signal with a signal processor to yield a value for the characteristic of the bulk material or powder. Also, the method includes transmitting a message flagging the storage bin when it is determined that the bulk material or powder is not suitable for continued storage. The bulk material or powder includes a dry cement or a dry cement component.

processing each of the output signals from the plurality of optical computing devices with a signal processor;
determining a characteristic of the bulk material or powder based on the processing of the output signals; and
transmitting an alert when it is determined that the bulk material or powder is not suitable for continued storage.

2. The method of claim 1 , wherein determining a characteristic of the bulk material or powder comprises determining a concentration of fines in the bulk material or powder.

3. The method of claim 1 , wherein determining a characteristic of the bulk material or powder comprises determining at least one of a humidity value and a contamination material content.

4. The method of claim 1 , further comprising associating a location in the storage bin with the characteristic of the bulk material or powder for each of the plurality of optical computing devices.

5. The method of claim 1 , further comprising transmitting a validation message when it is determined that the bulk material or powder is suitable for continued storage.

6. The method of claim 1 , further wherein transmitting an alert comprises closing a valve in a transfer tube coupling the storage bin with a scale tank in a system for storing and conveying raw materials.

7. The method of claim 1 , wherein receiving an output signal from each of a plurality of optical computing devices comprises wirelessly receiving at least one output signal from one of the plurality of optical computing devices.

8. The method of claim 1 , further comprising transmitting a command to at least one of the plurality of optical computing devices for interacting a sample light with an integrated computational element to obtain the output signal.

9. The method of claim 1 , further comprising transmitting a command to at least one of the plurality of optical computing devices for illuminating the bulk material with an electromagnetic radiation to obtain the output signal.

10. The method of claim 1 , wherein receiving an output signal from each of a plurality of optical computing devices comprises receiving an electromagnetic radiation interacted with the bulk material and modified by an integrated computational element, and receiving at least one compensating signal indicative of radiating deviations of an electromagnetic source of the electromagnetic radiation.

11. The method of claim 1 , wherein the bulk material is transported on a pipeline, and receiving an output signal from each of a plurality of optical computing devices comprises receiving an output signal from an optical computing device located inside the pipeline.

12. A device comprising:
a processor circuit; and
a memory circuit storing commands, which when executed by the processor circuit cause the device to:
