CE Three phase Current Probes Air-Core Coil DC 4-20mA

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

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 env

• ironment, look at my body again, light weight, flexible and robust.

• I’m a superman, I can big or small. My coil length can between 500px to 5000px, 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.
