ProSys has produced a new generation of high-performance flexible current probes based on Rogowski technology.
The accompanying photograph shows the green measuring head, which is available in various lengths. The standard length is 610 mm, which will fit a circular conductor of up to approximately 195 mm in diameter. Other lengths are available to order, eg, 381 mm, 915 mm and 1220 mm. The complete probe consists of the measuring head, (Rogowski coil) connecting cable between head and integrator, integrator and output cable, which is terminated with a safety BNC male connector.
Standard units have three current ranges – 30 A/300 A/3000 A, while calibrations for 60 A/600 A/6000 A are available upon request, in each case providing an output of 3 V. The probes have a bandwidth from 10 Hz to 10 kHz with an accuracy of ±1%. This latest generation has extended battery life of 2000 hours from two AA size alkaline cells.
