Product Description D1 Industrial integratorD1 is a Industrial Rogowski coil integrator installation in distribution box,in a plastic 1 module DIN-RAIL enclosure, powered directly from the mains.What does Integrator do?? Rogowski coil output is weak voltage mV signal,D1 has ability to amplify and convert it to standard signal which could be catched by multimeter and scope.? Rogowski coil output is proportional to the frequency of the measured current, the signal equalization ensure a linear response on a wide frequency range. D1 allows to use coils on different electrical network frequencies, keeping the same output level over the frequencies.? An integrator is essential to equalize and shift by 90° the output signal from the Rogowski coils. It consists of an active electronic circuit with negligible offset and a good linearity.FeatureD1 can be combined with any model and size of Y-FCT or FCT Rogowski coils.The available values are: 0-5VDC,0-5VAC,4-20mAC.On request the input value can be customized according to the application.D1 and Rogowski coil is a very flexible system, suitable for high power load analysis, impulsive current monitoring, DC ripple measurement, etc.Due to its specific features, flexible Rogowski coil is an extremely comfortable solution for current measurement and can be used in a number of cases where traditional current transducer is not the adequate solution. Advantage? High read accuracy 0.5% ? Easy to install with DIN-RAIL? High bandwidth for measurement 5 to 20kHz?

High current measurement? PLC controlWhat is a Rogowski coil?Rogowski coils have been used for the detection and measurement of electric currents for decades. They are based on a simple principle: an "air-cored" coil is placed around the conductor in a toroidal fashion and the magnetic field produced by the current induces a voltage in the coil. The voltage output is proportional to the rate of change of current. This voltage is integrated, thus producing an output proportional to the current.By using precision winding techniques, especially developed for the purpose, the coils are manufactured so that their output is not influenced by the position of the conductor within the toroid, and to reject interference from external magnetic fields caused, for example, from nearby conductors.Basically, a Rogowski coil current measuring system consists of a combination of a coil and conditioning electronics.Rogowski coil current transducers are used for the AC measurement.They can be used in similar circumstances to current transformers but for many applications they have considerable advantages:? Wide dynamic range.? High linearity.? Very useful with large size or awkward shaped conductors or in places with limited access. Thanks to the structure without hard core, the coil can be easily manufactured according to the application or to the available space.? Unlike traditional current transducers, there is no danger from open-circuited secondaries.? They cannot be damaged by large overloads.? They are non-intrusive. They draw no power from the main circuit carrying the current to be measured.? They are also light weighted and in some applications are light enough to be suspended on the conductor being measured.The transducer does not measure direct currents but, unlike a current transformer, it can carry out accurate measurements of AC component even if there is a large superimposed DC component, since there is no iron core causing saturation. This feature is particularly useful for measuring ripple currents for example in battery charging systems.
