What are Eddy current sensors? | Skill-Lync

Eddy currents can be used to measure the minute changes that happen in big machines. They can detect any change in shape, and hence can be used as a cautious system to prevent any major accidents on big sites from happening. Eddy current sensors consist of a conductor through which an alternating electric field is flowing, and because of this, the magnet develops a magnetic field of its own. When a metal is brought around the current-carrying conductor, the metal gets induced with current, known as eddy currents. This conductor, having developed an induced current, now has a magnetic field of its own which opposes the magnetic field of the current producing it. This relation is used in many machines. If there is a change in the flux noted, then the machine is checked for any flaws.

Accurate and repeatable measurement of flow is a requirement for industrial processes, including feed streams, tank recirculation loops, product transfer lines, and many others. In this video, we will - Introduce you to the working principles of a magnetic flow sensor, - Describe the physical characteristics of a magnetic flow sensor that make it valuable for process control, - Describe the ways magnetic flow sensors can be integrated into a measurement and control system. Magnetic flow sensors convert the velocity of a flowing fluid into a measurable electrical signal that is proportional to the flow rate. Magnetic flowmeters have no moving parts or internal flow path obstructions, so they are easy to calibrate and maintain. Because magnetic flow meters are typically specified to be the same size as the upstream and downstream piping, there is virtually no pressure loss through the flow meter, which can be very advantageous for some flow streams, like thick slurries. Magnetic Flow sensors are often called mag meters, and we will refer to them using this abbreviation. Mag meters are typically full-bore sensors, meaning that the internal flow path is of the same diameter as the upstream and downstream connections. This construction eliminates any restriction of the fluid which may alter the flow path or create a pressure drop. Fluid passes through the mag meter in a straight line through the bore of the sensor. This regular, cylindrical geometry also allows a constant and directional magnetic field to be established across the diameter of the flow path. The magic that creates the flow signal is based in the magnet! The mag meter is surrounded by an iron-core, permanent magnet that creates a magnetic field to be established with lines of magnetic flux which pass vertically through the entire cross-section of the pipe and the flowing fluid. This geometry is very important. The flowing fluid will pass through these lines of magnetic flux at a 90-degree angle or perpendicular to the lines of magnetic flux. To generate a voltage according to Faraday’s law, we must have a moving conductor. The conductivity of liquids is measured in units of micro-Siemens-per-centimeter. Some fluids, such as seawater, have high conductivity, and seawater flow can be measured with a mag meter. In addition to seawater, flows of wastewater, and ionic solutions such as acids can easily be measured by magnetic flowmeters. When installing a magnetic flow meter in process piping, it is vitally important to follow the manufacturer’s recommendation for grounding. The electrical signal produced in a mag meter is a very small DC voltage, and stray voltages along a pipe due to welding equipment or other large electrical loads in the plant. Transmitters are always used with mag meters. They convert the small DC voltages generated by the flowing fluid into signals that can be connected to the control system. 4 to 20 milliamp, Profibus PA, Foundation Fieldbus, and IO-Link transmitter outputs are available. When specifying magnetic flowmeters, some important aspects must be considered in addition to the conductivity of the fluid and the need for grounding rings. If the fluid is corrosive or abrasive, a compatible liner should be specified. These liners can also be replaced if they become worn, and they do not affect measurement accuracy. ============================= Get a RealPars pro membership: https://learn.realpars.com/bundles/pro ============================= Missed our most recent videos?

How to Measure Flow with Magnets - (Magnetic Flow Meters)

What happens when a civil engineer mixes water and electricity? The results aren't always ideal, but you always learn something! A magnetic flow meter relies on Faraday's Law of Induction to measure the flow of a fluid. Magnets outside the pipe create a magnetic field. Electrodes are located perpendicular to the magnets. A conductive fluid moving through the pipe will generate a voltage (electromotive force) between the electrodes due to Faraday’s law. The faster the fluid moves through the pipe, the higher the voltage. Once you know the velocity of the fluid, you can calculate flow using the cross sectional area of the pipe. In this video, I walk through some of the details that electrical engineers have worked out so that this ingenious device can work properly. Unfortunately I couldn't get it working very well myself!
