1、Mainly used for the detection of AC leakage current, large current, high order harmonic current (up to 400 times), complex waveform current, transient impulse current, phase, electric energy, power, power factor, etc. 2、Using advanced technology, it is a toroidal coil that is evenly wound on a non‑ferromagnetic material, with no hysteresis effect, almost zero phase error, no magnetic saturation, and extremely high linearity. 3、For the flexible coil CT, the output signal is the differentiation of current with respect to time. By integrating the output voltage signal, the input current can be truly restored. 4、The ETCR‑FA series flexible coil current sensor is composed of a coil and a handle. The coil part has no exposed metal conductors. It is non contact measurement, safe and reliable. 5、It is small in size, light in weight, exquisite in appearance, soft and flexible, and is suitable for narrow environments and places with dense cables. Item Type: Flexible Coil Current Sensor Material: ABS Color: As shown in the picture Model: ETCR500FA Application: With an integrator, it is easy to integrate into other equipment, such as phase detection analyzers, industrial control devices, data loggers, oscilloscopes, harmonic analyzers, power quality analyzers, high-precision digital multimeters, transient impact recorders, Distributed measurement system, protection system, etc. Function Detection of AC leakage current, large current, high-order harmonic current, complex waveform current, transient inrush current, phase, electric energy, power, power factor, etc. Detection method Flexible coil CT: The output signal is the differentiation of current with respect to time. By integrating the output voltage signal, the input current can be truly restored Coil diameter Φ7.5mm Quantity process 0A~10000A~higher Resolution 10mA Accuracy class ±1.0%FS (50Hz/60Hz; 23℃±2℃, below 70%RH, the wire is at the center of the coil) Phase error ≤0.1°(50Hz/60Hz; 23℃±2℃) Output Interface 3.5mm audio frequency plug/BNC plug/tap (optional), cable length 2M Electric field interference No hysteresis effect, no interference from external electric field Wire position The wire to be tested is at the center of the coil, and the position error affects ≤±0.3%FS Current frequency 45Hz~70Hz (frequency of measured current) Response frequency 0.1Hz~1MHz Line voltage Line test below AC 1000V Working temperature and humidity -20℃~50℃; below 80%rh Storage temperature and humidity -10℃~60℃; below 70%rh Dielectric strength AC 2000V/rms (both ends of the coil after unlocking and unfolding) Suitable for safety regulations CAT IV 600V, CAT III 1000V 1 x Flexible Coil Current Sensor
