Rogowski Coil MFC150 (8 mm cross section) is a flexible current sensor based on 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 transformers are not fitting due to size and/or weight.

Functions
It is based on a simple principle: an “air-cored” coil is placed around the conductor in a toroidal fashion; the magnetic field produced by the current induces a voltage in the coil. The voltage output is proportional to the rate of change of current. This voltage is integrated, thus producing an output proportional to the current. The output voltage is proportional to the change in current, and after an operational amplifier integrator, is proportional to the value of the current itself.
Key strengths
- Two available models: with or without integrator
- Suitable to measure currents from mA to several kA
- High linearity
- Very useful with large size or awkward shaped conductors or in places with limited access
- No danger from open-circuited secondary
- Not damaged by overloads
- Non-intrusive, no power drawn from the main
- Thanks to its light weight, it can be changed on the measured conductor
- Totally shielded
- Optional UL Recognized Component Mark UL 61010-1
