Product Introduction
ETCR002F Flexible Coil Sensor With Integrator(Integral), also known as Rockwell coil current sensor, Roche coil sensor, flexible current clamp, lightning strike current sensor, is used for current, high-order harmonic current (up to 400 times), complex waveform current, transient inrush current, phase, electrical energy, power, power factor and other detection.After being equipped with an integrator, it can be more easily integrated into other test equipment, such as power quality analyzer, harmonic analyzer, power parameter recorder, phase detection analyzer, industrial control device, oscilloscope, high-precision digital multimeter, transient impact recorder, distributed measurement system, protection system, etc.
ETCR002F Flexible Coil Sensor With Integrator(Integral) consists of an integrator and a coil. The coil part does not have any exposed metal conductors, non-contact measurement, safe and reliable; its small size, light weight, exquisite appearance, soft and flexible, suitable for narrow environments and places with dense wiring; wide measurement range, high accuracy, strong reliability, wide response frequency band, users can customize the coil length according to their needs.It is widely used in electric power, communications, meteorology, railways, oil fields, construction, metrology, scientific research and teaching units, industrial and mining enterprises and other fields.It is particularly suitable for industrial environments with severe signal distortion such as relay protection, SCR rectifier, frequency conversion speed regulation, semiconductor switching, power electronic conversion equipment, arc welding, etc.
1. The integral integrator can be equipped with flexible coils of various lengths, which is particularly convenient for on-site use.
2. Non-contact measurement, safe and reliable.The measurement range is wide, the accuracy is high, the reliability is strong, and the response frequency band is wide.
3. The integrator is small in size and light in weight, and the flexible coil is soft and flexible. It is suitable for narrow environments and places with dense wiring, as well as for measuring the current of conductors with large sizes or irregular shapes.
4. The coil length can be customized according to customer requirements.
