Flexible Current Probe SymmProFlex®

Precision Flexible AC Current Probe based on Rogowski principle for current, power, energy and electricity quality applications

Precision Flexible AC Current Probes SymmProFlex® FCP 211x, FCP 311x and FCP 331x are current probes based on Rogowski principle designed to measure alternating current up to 3000 A, 6000 A or more.

Current Probes SymmProFlex® FCP 211x series can be used with any multimeter, scopemeter or other current or power measuring apparatus.

Current Probes SymmProFlex® FCP 311x (single-phase) and FCP 331x (three-phase) are designed for usage with measuring equipment which is able to use I2C communication for accessing software calibration parameters stored in probe’s internal EEPROM memory.
