Squirrel Dataloggers For Energy Management
Eltek produce and stock a range of transducers tailored for the Energy industry which interface to the 1010/1020 dataloggers:
RC1000 Rogowski Coil
The Rogowski coil is a current transducer that permits measurement of current in a conductor up to 2000A. The coil is not a fixed closed loop, the end is looped about the conductor and parked in the fitting at the base of the loop.
Method C is frequently used without problems, method D is however the preferred method of use.
The Rogowski coil lends itself perfectly to being fixed round irregular shaped objects, including fuse assemblies, in difficult-to-access locations. The loop is normally hung over the conductor for temporary or permanent current measurement.
The Squirrel logger input includes an integrator that dispenses with the need for an external device, providing a cost effective and compact measuring system. The coil is independent of frequency.
The Squirrel provides the following ranges when used with the Rogowski coil:
Note: Accuracy of measurement at the low end of the scale (that is <1% of maximum) can be variable.
