Flexible probes for AC current Pinces ampèremetriques pour courant AC MiniFlex® series Serie MN MiniFlex® SERIES Making use of the principle of Rogowski coils, the MiniFlex® models are flexible sensors offering a wide dynamic range for measuring AC currents and viewing high-speed current pulses. The sensor’s output voltage is proportional to the derivative of the current measured in the conductor and requires an electronic system for formatting. The absence of a magnetic core at the centre of the coil brings several advantages: - flexibility and light weight - excellent response to rapid current changes, as it is not possible for induced Fourier currents to occur, so they do not increase the sensor’s response time. - excellent linearity due to the absence of core saturation even when there are very high current, as in the case of electric power transmission, electrical welding or applications involving high-power pulses. The great care taken when manufacturing our sensors means they benefit from particularly homogeneous winding, with equidistant turns along the whole length of the sensor, thus ensuring good immunity against electromagnetic interference. The MiniFlex® models are made up of a flexible sensor connected to a casing containing processing electronics which outputs a voltage with the same amplitude and form as the current measured. Non-contractual document With their small diameter and size, the sensors in the MA110 series are ideal for measuring currents in the electrical cabinets of residential or tertiary buildings or in low-power cabinets in industry. The rugged clicktogether system benefits from IP67 ingress protection. Available with "banana" or "BNC" connection technology, the MA110 series can be connected directly to a multimeter, a wattmeter or a logger for RMS measurements at the standard industrial frequencies. The casing offers 4 measurement calibres. The MA130 sensor, part of the same series as the MA110, can be used to measure currents on three-phase installations. It is equipped with BNC connections with adapters for banana plugs. The processing unit offers 3 measurement calibres. The rugged click-together system has IP67 ingress protection. It can be connected to the AC voltage inputs (mV AC, AC) of any power analyser, logger or other measuring instrument. The MA200 series is a family of "high-frequency" sensors specially designed for viewing and measuring electrical or electrotechnical signals with wide variations and high amplitude. These "insulated current probes for oscilloscopes" offer a bandwidth of 1 MHz and can be used to analyse currents with complex forms, transients present in electronic power supplies, welding units
