Product Introduction
Musktool-ETCR002F flexible coil current sensor (with integrator), composed of a flexible coil and a host, the integral structure is more convenient to use and operate. There is no exposed metal conductor in the coil part, non-contact measurement, safe and reliable; its small size, light weight, beautiful appearance, soft and flexible, suitable for narrow environments and places with dense wiring; wide measurement range, high precision, strong reliability, Response frequency bandwidth (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 flexible coil is the differential of current to time. The integrator integrates the output voltage signal (0~1V) to truly restore the measured current and output a complete signal waveform. The measured current range can range from 1 ampere to tens of thousands of amperes. Mainly used for detection of current, high-order harmonic current (up to 400 times), complex waveform current, transient impact current, phase, electric energy, power, power factor, etc. Equipped with an integrator, it can be more conveniently integrated into other test equipment, such as power quality analyzers, harmonic analyzers, power parameter recorders, phase detection analyzers, industrial control devices, oscilloscopes, high-precision digital multimeters, transient Shock recorder, distributed measurement system, protection system, etc. |
