Product Introduction
Musktool-ETCR-FA series flexible coil current sensor is composed of a coil and a handle. The coil part does not have any exposed metal conductors, non-contact measurement, safe and reliable; its small size, light weight, beautiful appearance, soft and flexible, suitable for narrow environments and dense wiring The place; wide measurement range, high precision, strong reliability, wide response frequency (0.1Hz-1MHz), users can customize the coil length according to their needs. Using advanced Rogowski coil technology, it is a toroidal coil wound evenly on non-ferromagnetic materials, without hysteresis effect, almost zero phase error, no magnetic saturation phenomenon, and extremely high linearity. 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 range can range from milliamps to tens of thousands of amperes. It is mainly used for the detection of AC leakage current, large current, high-order harmonic current (up to 400 times), complex waveform current, transient impact current, phase, electric energy, power, power factor, etc. With an integrator, it is easy to integrate into other equipment, such as phase detection analyzers, industrial control devices, data recorders, oscilloscopes, harmonic analyzers, power quality analyzers, high-precision digital multimeters, transient impact recorders, distributed Measuring systems, protection systems, etc. |
