Product Description Product DescriptionIntroduction to Rogowski coilRogowski coil also called differential current sensor, it is a "hollow" circular coil, arranged around the conductor, so that an alternating magnetic field generated by the current induces a voltage in the coil. The coil is actually a transformer coupled to the conductor under test, and the voltage directly output from the coil is proportional to the rate of change of current, e.g. @50Hz/1kA Vout=1000mV,@60Hz/1kA Vout=1000*60/50=1200mV. If you want to obtain the current waveform or current value that doesn't matter to frequency also need to add the integral circuit to achieve 90° phase shift compensation and frequency equalization. The RHS series is a rogowski coil-based current sensor with different sizes available for light weight and low price, or can be ordered specifically according to the customer's design requirements. Non-magnetic saturation and shielding protect against external magnetic fields, resulting in stable measurements from low currents to hundreds of kA.Accurate measurements are available in smart meters, industrial motor control and power monitoring applications. Systems that use an ADC chips(ADS131M04) or a power metering ICs(ADE7753) that support the Rogowski coil principle are even more advantageous.We provide 4-20mA, 0-5V, 0-1A, 333mV and other integrators suitable for more usage scenarios.Features ApplicationHigh dynamic range, 1A-100kA Smart grid applicationsNo danger of opening A new generation of sensors for solid-state energy metersExcellent linearity High-precision power metersNo load consumption for theconductor under test AC component fault detector for DC currentHigh bandwidth output characteristics Electric vehicles (cars) and solar applicationsVery low temperature coefficient Harmonic measurement sensorStrong DC anti-interference abilityElectrical parametersModelRHSP-12-1000Window diameter12.8mmWeight22gCoil internal resistance240(±5)ΩRated current≤500KAAccuracy<0.5%25oCPosition error±1%Output voltage1000mV/KA@50Hz 1200mV/KA@60HzFrequency range10Hz~20KHzLinearity±0.2%(10%~100%of rated value)Phase shift≤0.5°Working temperature-30C~+80oCStorage temperature-40oC~+80oCDimensions and DiagramNotice:1. According to the Rogowski coil principle, the output voltage is directly related to the conductor (di / dt) of the input current. 2. The output voltages are sine waveforms of a constant rated frequency in Hz and are measured at RMS values. 3. Vout (RMS) = Amps (RMS) × Hertz×K×10-6, where K depends on the manufacturer, 1000mV model K value is 20.Warning:Do not apply pressure to the coil by any form of mechanical force (e.g., twisting, piercing, excessive pressure, excessive bending, etc.), which will reduces the accuracy of the device greatlyMain ProductCompany ProfileYHDC was established in 1992 and is a leading manufacturer of electromagnetic components and devices.
