Product introduction
MEWOI-002G flexible coil current sensor (with integrator) is a separate integrator. The sensor is composed of an integrator and a coil. The separate integrator can be combined with GA and GB coils flexibly and conveniently. 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; response frequency bandwidth (0.1Hz-1MHz), users Coil lengths can be customized upon request. 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 EActor, 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. |
