Modern solutions for efficient storage processes in grain, standing and flour silos
What can happen if plant engineers choose unsuitable measurement technology in their applications? In addition to overfilling of the silo or reduced productivity, production may even come to a halt. When choosing measurement sensor technology, plant operators should therefore always be careful to use high-quality and reliable system components in line with the changing challenges, depending on the process. The rotating paddle detector, which detects limit levels in silo containers according to the rotation principle, can be found in almost every grain processing plant.
Special solutions with increased corrosion resistance of point level measurement equipment
Performance failures of level sensors cause costs to rise – not only due to the interruption of process but also when the replacement and commissioning of the devices become time-consuming. Capacitive RF probes with full coating protection as a safe and reliable measurement solution especially in flue gas cleaning.
RF measurement in clean and contaminated acetone for synthetic fiber manufacturer producing special protective clothing and packaging solutions
Single-rod probes using the capacitive measuring method are in many cases a clever solution when it comes to level detection. They can be found in overfill protection and as demand or empty detectors in process or storage containers. These limit switches are suitable for almost all bulk materials from different industries, due to high sensitivity, high mechanical load and the variety of probe extensions. But these qualities also make them a suitable solution in the fascinating world of varied liquid applications, be they in food, wood, rubber, plastics, environmental and power plants, building materials and chemical industries. The use of the RFnivo® capactive rod is fully explained here within the textile production process featuring the aggressive substance of acetone. The Rotonivo® rotary paddle switch having provided the solution for many years for the plant operator, this time the application required an alternative answer from the UWT team.
In order to define the correct level measurement technology it is essential to analyze the different process parameters of the single application such as material properties, process temperatures, pressure and connections as well as the process atmosphere. The selection of the right level measurement technologies, their correct configuration and smart positioning will save substantial costs and add up to a significant improvement in the plants’ economic efficiency over its lifecycle.
Continuous level measurement between double filling: Optimum echo quality & dust-tight design make it possible
Many an inconspicuous component part can quickly become a problem if it does not function reliably. In the case of level monitoring, for example, cost-causing silo overfilling or running empty, which can result in a production standstill, are avoided. In order to integrate sensors perfectly into plants, the highest process compatibility is required for the individual production stages, as well as a certified design. For an animal feed producer in Chile, it should also be a non-contact measurement technology for the storage of powdered raw materials, which operates under high dust generation during the dynamic filling process.
When configuring a suitable sensor system for the plant operator, the focus was on process reliability, durability and simplicity. Furthermore, the requirements for the special installation situation had to be taken into account.
For the cellulose production of a wood manufacturing plant in South America, the guided wave radar was implemented in several water tank constructions within the maceration processes. The modern, high-quality TDR technology ensures a continuous production process of the plant. Uninfluenced by changing process conditions, TDR sensors detect the level reliably and precisely and thus offer optimum support for a smooth process flow.
Concerning precise interface measurement of different solids in liquids there are popular project planning options for continuous level monitoring with lot systems and point level detection with vibrating forks. A company in England who manufactures stone recovery plants for the quarrying industry implements the electromechanical plumb bob NivoBob® for the detection of interface levels with the right feeling for the separating layer. The operator was looking after a principle that is sensitive and simple.
Modern, high-quality technologies ensure a continuous stress-free manufacturing process in plants
When it comes to detecting fill levels in silos and material processing operations, sensors with a high level of compatibility for different process containers provide the optimum support for a smooth process. Depending on the processing stage, the material to be controlled can be of very different nature and place different demands on the measurement technology to be used. Users from different industries with a number of scattered storage silos consider it increasingly necessary for their plants to be equipped with automated visualisation and monitoring of the data in addition to continuous measurement of the fill levels.
