MEWOI9000G flexible high current clamp / logger is specially designed for field-line testing, monitoring, recording AC leakage current and Large current, It consists of host, flexible current clamps, monitoring software, communication lines and other components. Widely used in electric power, telecommunications, meteorology, railroad, oilfield, construction, measurement, research and teaching departments, industrial and mining enterprises and other fields. Particularly suitable for cable-intensive places, the wall transformer core grounding current test, thick wire cable test, relay protection , frequency conversion, semiconductor switches, electronic power conversion equipment, arc welding and other serious signal distortion current testing industrial environments. Flexible current clamp (Rockwell coil), apply to advanced Rockwell coil (or Rogowski coil) technology, is a uniform circular coil wound on a non-ferromagnetic material, no hysteresis effect is almost zero phase error, no magnetic saturation, high linearity, strong anti-interference ability. The output signal is a differential current over time, by integrating the output voltage signal , you can restore the real input current, the current measurement range from milliamps to tens of thousands of Amps. Flexible current clamp coil is without any exposed metal conductor, non-contact measuring, safe and fast; its small size, light weight, attractive appearance, soft and flexible, adapted to the environment and the narrow cable-intensive sites; high accuracy, reliability, response frequency bandwidth, users can customize the length of the coil according to actual demand. Host embedded in English interface, suitable for engineering and technical personnel of different countries. LCD display, at a glance. While having a relatively large storage space, can store 4200 sets of data, also has an automatic time setting function storage interval, the settings ranges from 1 to 60 minutes. Monitoring software supports on-line real-time monitoring and historical inquiry, dynamic display, wave indication; has a maximum, minimum, average indication; with alarm value setting and alarm indication; historical data read, access, store, sort, generate curves, printing etc. |
