Flexible Rogowski Coil
or call indoor coil current transoformer/flexible current transformer
Jiangyin Spark FCT is flexible, like rope ,it is designed to use where solid or split core current transformers cannot fit Advantage including high accuracy, wide measurement and frequency range and very light weight.The probes comprise a flexible air–cored sensor which can be opened, allowing them to be installed around a primary conductor without interrupting the circuit. The flexible and lightweight measuring head allows quick and easy installation in hard to reach areas and with large conductors.
Capable of accommodating a range of primary conductor sizes.
Characterized by high sensitivity, accuracy, linearity, minimum phase shift.
Suitable for harsh operating environments (temperature, humidity, EMI).
Current Range: 100A to 100kA
Accuracy: < 1%
Phase Shift: < 1 degrees at 50/60Hz (< 0.5 degrees typical) /li>
Linearity: ±0.2% from 10% to 100% of rated primary current
Primary Conductor Position Sensitivity: ± 2% maximum
Influence of External Field: ± 1.5% maximum
Coil Working voltage: 1000VRMS or 1000VDC
Coil Dielectric Surge Withstand: 5kVRMS for 1 minute
Operating temperature: -20ºC to +60ºC
Leads: Shielded cable, or as per customer need
Diameter: 6-50CM
Output: 5 kinds of output now:
- 0.33V output
- 0-5V output
- 0-10V output
- 4-20mA output
- 5A output.
Why choose a flexible rogowski coil from Jiangyin spark
People always ask me, why choose you, give us some reason.
I’m a flexible guy, look at my body, simple to retro-fit, I can be used in the complex environment, look at my body again, light weight, flexible and robust.
I’m a superman, I can big or small. My coil length can between 20cm to 200cm, so cool.
I’m a math genius and very sensitive to data, so my accuracy is perfect: ±1%.
I’m from elite school, all of my materials pass the UL Certifications and CE Certifications, and my team founded in 1995, they are the first on produce rogowski coil in china, they are the best in china, and they got some patents, so you can see my quality is competitive
As you know i’, m from china(cheap manpower), so I have a competitive price, (much cheaper than flexible rogowksi coil in Europe and America) I have sold to over 25 countries and can count major international companies, government bodies and research institutions as my customers, so you can see I’m a popular guy.
And I’m very safe-No danger of an open circuit secondary and galvanic isolation, of course my excellent linearity (I have no magnetic materials to saturate)
So remember my name: JIANGYIN SPARK flexible rogowski coil, and waiting for your enquire.
