Flexible Current Clamp PCE-CM 40

Flexible current clamp for up to 3000 A / Rogowski coil with a diameter of 170 mm / Inrush function / Frequency measurement / LC display

The flexible current clamp PCE-CM 40 is suitable for current measurements up to 3000 A AC. In addition to TRMS current measurement, the flexible current clamp can be used to measure inrush currents. The current measurement is performed using a flexible Rogowski coil. This means that the electrical conductor around which the flexible current clamp is placed induces a voltage in the ammeter. This voltage is proportional to the current flow through the electrical conductor. Thus, it is possible to measure very high currents with the flexible current clamp with minimal risk.

In addition to current measurement, the flexible current clamp can measure frequencies in the range of 50 to 400 Hz. The PCE-CM 40 flexible current clamp is used for measuring AC current in machines, systems, and electrical installations. Thanks to the flexible Rogowski coil, which has a diameter of 170 mm, the current clamp can be used in places where a conventional current clamp cannot be applied due to space constraints. The measured value of the alternating current is displayed on the illuminated LCD. Furthermore, the measurement values can be stored in memory, which can be accessed via the Bluetooth interface.
