ROCOIL柔性线圈1000系列介绍
Rocoil® 1000 型柔性罗氏线圈有多种长度和横截面直径以及屏蔽和非屏蔽版本。借助合适的电子积分器，这些线圈可用于测量分辨率低至 1mA 的低电流和大于 1MA 的高电流。罗氏线圈传感器与被测电路完全隔离，即使对于阻抗非常低的电路，也不会影响被测电流。
The Rocoil® Type 1000 flexible Rogowski coils are available in a range of lengths and cross-sectional diameters as well as in screened and un-screened versions. With a suitable electronic integrator these coils can be used to measure low currents with a resolution as low as 1mA and high currents of greater than 1MA. The Rogowski coil sensors provide complete isolation from the circuit being measured and have no effect on the current being measured even for very low-impedance circuits.
