Xtester-ETCR8300F three channels Flexible Coil Leakage Current Monitoring Recorder/Logger
INTRODUCTION
Xtester-ETCR8300F Three Channel Flexible Coil Current Monitoring Recorder esigned and manufactured for on-site simultaneous monitoring and recording 1-3 channel AC current or leakage current, it is composed of recorder host, flexible current clamps, charger, monitoring software and communication cable, etc. Widely used in electric power, communications, meteorology, railway, oil field, construction, measurement, scientific research and teaching units, industrial and mining enterprises and other fields. It is especially suitable for the current test in the industrial environment where the signal is seriously distorted, such as the flat cable dense place, large special-shaped wires, relay protection, thyristor rectifier, frequency conversion speed regulation, semiconductor switch, power electronic conversion equipment, arc welding and so on.Host adopts LCD display, three channels with the same screen display, clear at a glance, there are Chinese and English operation interface two choices, suitable for different countries of engineering and technical personnel. The recorder equipped large capacity rechargeable lithium battery, display power energy with a three-grid mode, which can continues recording up to 7 days. With the function of system clock and super storage space, it can set the monitoring and recording time on site, can store 200,000 sets of data, and has the function of setting the interval time of automatic storage, setting from 1 to 99 minutes. Monitoring software has online real-time monitoring and historical query functions, historical data reading, consulting, saving, reporting and other functions. Flexible current clamp, Rogowski Coil, adopts advanced Rogowski Coil technology, which is a loop coil uniformly wound on non-ferromagnetic materials, with no hysteresis effect, almost zero phase error, no magnetic saturation, high linearity and strong anti-interference ability.The output signal is the differential of the current with respect to time. By integrating the output voltage signal, the input current can be truly restored. The measured current ranges from milliamperes up to ten thousands of amperes.Flexible coil without any exposed metal conductor, non-contact measurement, safe and reliable. Small size, light weight, soft and flexible, suitable for narrow environment and flat cable dense places. High measurement accuracy, strong reliability, wide response frequency band, the user can customize the coil length according to demand. |
