Ⅰ. Brief
ETCR001F Flexible coil current sensor (Integrator), Rockwell coil Current Sensor, using advanced Roche technology, is a non-ferromagnetic material in the uniform winding of the coil, no hysteresis effect, almost zero phase error, non-magnetic saturation phenomenon, high linearity. The flexible coil is the derivative of the current to time. The integrator integrates the output voltage signal (0 ~ 1V), realizes the measured current and outputs the complete signal waveform. The measuring current range from 0.1A to tens of thousands amperes. Mainly used for current, high harmonic current (up to 400 times), complex waveform current, transient impact current, phase, power, power, power factor detection. Equipped with integrator can be more easily integrated into other test equipment, such as power quality analyzer, harmonic analyzer, power parameter recorder, phase detection analyzer, industrial control devices, oscilloscopes, high-precision digital multimeter, transient Impact recorder, distributed measurement system, protection system.
ETCR001F Flexible coil current sensor (Integrator), Coil part without any exposed metal conductor, non-contact measurement, safe and reliable; Its small size, light weight, beautiful appearance, soft and flexible, suitable for narrow environments and cable-intensive places; Wide measurement range, high accuracy, high reliability, response frequency bandwidth (0.1Hz-1MHz), the user can customize the length of the coil. Widely used in electricity, communications, meteorology, railways, oil fields, construction, measurement, scientific research and teaching units, industrial and mining enterprises and other fields. Particularly suitable for relay protection, SCR rectifier, frequency control, semiconductor switches, power electronic conversion equipment, welding and other serious signal distortion of the industrial environment.
