  Flexible Rogowski Coil         FCT is a flexible current probe utilizing the Rogowski principle,which is suitable to conveniently measure single and three phase AC as well as pulsed DC currents. After appropriate signal conditioning, it can be used with digital multimeters, recorders and other suitable equipment to measure current from very low frequencies up to 1MHz.     The probes comprise a flexible air–cored sensor which can be opened, allowing them to be installed around a primary conductor without interrupting the circuit. The flexible and lightweight measuring head allows quick and easy installation in hard to reach areas and with large conductors.     Available Models
