- Rogowski Coils MFC150 (8 mm cross section) are flexible current transducers based on the Rogowski principle.
- MFC150 coils are available in different sizes and can be supplied according to customer’s design, therefore they can be used in all those applications, in which traditional transducers are not fitting due to its size and/ or weight.
- MFC150 coil is provided with a shield against the influence of external magnetic fields, therefore it grants a stable measurement from low currents to hundreds of kA.
- The Rogowski coils must be connected to an electronic integrator.
- Algodue power meters UPM209 and UPM309 can interface Rogowski coils directly without the need of the external integrators (Smart kits). This is an advantage because there is no external boxes or any power supply with consequent ease of use.
- MFC150 can be also provided with built-in integrator, without needing of external devices for 90° phase shift compensation and frequency equalization. This is an advantage because there is no external box with consequent ease of use.
- Algodue power meters UPM209 and UPM309 can interface Rogowski coils directly without the need of the external integrators (Smart kits).
- New version completely redesigned
- Delivered already calibrated
- Very thin coil diameter: down to 8 mm
- Newly designed and enhanced bayonet connector including possibility to regulate calibration
- Improved accuracy
- Measurement uniformity at any position of the conductor inside the coil
- Excellent degree of rejection to the external current conductor
- Different coil colours available based on quantity
Highlights
- Suitable to measure currents from mA to hundreds of kA
- High linearity
- Wide dynamic range
- Very useful with large size or awkward shaped conductors or in places with limited access
- No danger from open-circuited secondary
- Not damaged by large overloads
- Non-intrusive, no power drawn from the main
- Thanks to its light weight, it can be changed on the measured conductor
- Totally shielded
- UL file n. E231725
