How RF Technology Works

RF Technology Decoded by UWT – How Electrical Signals Deliver Reliable Level Detection RF technology (Radio Frequency Capacitance) uses high-frequency measurement for precise level detection. Unlike purely capacitive sensors, it detects not only changes in capacitance but also the specific resistance of the medium. This ensures reliable measurement even under challenging conditions. How does RF technology work? The principle is based on an electrical voltage divider. Together with the medium, the probe forms a measuring system that detects both capacitance and impedance. Impedance describes the total electrical resistance a medium presents to an alternating current. It indicates how strongly a material reacts to electrical signals – and this change is exactly what RF technology uses for reliable detection. When the material comes into contact with the electrode, the capacitance increases abruptly – a clear signal that the level has been reached. The longer the active electrode, the more sensitively the probe responds. This allows the measurement…

Continuous & point level measurement with guaranteed Quality

Level detectors detect media at a predefined position depending on the installation position. Level detectors are mainly installed as full or empty detectors in the upper or lower part of a silo or container. This prevents the silo from overfilling or running empty. In combination with a level sensor, this results in a redundant system which additionally increases plant safety. If a certain fill level is of particular interest, the sensors can also be used as demand detectors. There are different technologies for level detection, which have their advantages and disadvantages depending on the application. For the selection, numerous process conditions have to be considered, which the sensor technology has to cope with. In addition, the requirements for bulk solids sensors differ from those for liquid sensors. For this reason, UWT offers a broad portfolio of different technologies such as rotary paddle switches, vibration level switches and capacitive sensors.

Upgrade of level monitoring system in grain storage

A large grain storage facility in the south of England required a reliable content measuring device to replace an old acoustic wave system which was no longer functioning. Configured was a non-contact radar measurement device from UWT combined with a visualization software. Non-contact continuous level measurement UWT (UK) Limited proposed the use of the free-radiating radar NivoRadar® NR 3100 which could be supplied with an aiming flange. The integrated aiming flange allowed the radar to be mounted in the same position as the previous acoustic wave device which was close to the silo side wall and which allowed for the narrow 4˚ beam to be aimed towards the lowest point of the silo. This saved the customer time and money as they didn’t need to move the mounting position towards the centre of the silo where the silo was filled from. Free-radiating radar sensors can determine the level of a medium without contact. The so-called FMCW radar measurement method (Frequency Modulated Continous Wave) is used for this purpose. The transmitted signal is modulated between two known frequency values (NivoRadar® 78...79 GHz) and the difference…

Upgrade of level monitoring system in grain storage

A large grain storage facility in the south of England required a reliable content measuring device to replace an old acoustic wave system which was no longer functioning. Non-contact continuous level measurement UWT (UK) Limited proposed the use of the free-radiating radar NivoRadar® NR 3100 which could be supplied with an aiming flange. The integrated aiming flange allowed the radar to be mounted in the same position as the previous acoustic wave device which was close to the silo side wall and which allowed for the narrow 4˚ beam to be aimed towards the lowest point of the silo. This saved the customer time and money as they didn’t need to move the mounting position towards the centre of the silo where the silo was filled from. Bring the levels to where the planner needs them The visualising system that the customer had been using previously was very basic and limited and did not allow them to display the contents in any other way than the level of the material. The customer required the contents of the silo to be displayed in tonnes or percentage of fill. The NivoTec® NT 4600 with cabinet mounted digital display fulfilled…

Silo management with NivoTec® for grain mills and their customers

Bakeries, the customers of the mills, often place their orders to late and the mills are faced with having to supply material immediately in order to avoid production stop at the bakeries. In Germany alone there are more than 260 large flour mills, in Asia the grain market is significantly greater and a very important industry. All around the world the situation is similar: Well-planned routes and carefully calculated stock levels are vital to achieve max. cost optimization during the material delivery process, however these are more than often jeopardized by daily reality. This leads to unnecessary logistics costs caused by multiple deliveries and ultimately to an increase in costs for sides, the supplier and the customer. This is obviously in no one’s interest. But why are we confronted with these “fire-fighting” situations and how can they be avoided? Lack of storage management in bakeries Even bakeries with multiple storage silos often do not have an automated level monitoring system to control their inventory levels. Therefore these stocks have to be checked manually on a regular basis and an order has to be triggered to the flour supplier…

Depending on the application, the following information can be obtained from the reflected waves: -the angle or the direction to the object -the speed of an object (Doppler effect) -the contours of an object -the distance to the object The latter point means that radar technology is also used for determining fill levels. This has become increasingly important in recent decades and has been continuously developed. The areas of application now extend from simple storage tank applications to complex process containers with a wide variety of challenges.

Capacitance point level detection in liquid naphthalene

UWT application of the month Full detection with high process compatibility in chemical plant operation The measurement technology a chemical plant was looking for in his liquid naphthalene tanks has to deal with different temperatures, varying DK values and viscosity. In order to meet these conditions in practice quickly and reliably with a clever solution, the capacitive rod probes of the RFnivo® series from UWT were implemented. Changing process temperatures and caking on the sensor boom In the liquid state, naphthalene is an aggressive substance that quickly corrodes common materials. If it becomes firmer as it cools down, it tends to become heavily attached. For the individual tanks with liquid naphthalene, the system operator therefore needed reliable and robust level monitoring, which can be flexibly adapted to the fluctuating ambient conditions. The chemical manufacturer has several storage tanks that are electrically heated to maintain the melting point of the naphthalene. There is…
