- 1D, 2D and 3D Helmholtz Coils -

Standard coils available by the moment, with Ferronato^® trademark

BHC-2 and BHC-2RF

Miniature calibration coils, ideal to check magnetometers at the field, these also have many other applications.

BH300HF-3-B

Three axes coil-set of 300 mm in nominal diameter, to operate at high frequencies to about 300 kHz.

-  Details of the BHC-2  -

BH300-3-A

Three axes coil-set of 300 mm in nominal diameter, for laboratory and general uses. It can be also supplied in versions of one or two axes.

BH1300-3-A

Three axes coil-set of 1300 mm in nominal diameter, for laboratory and general uses. It can be also supplied in versions of one or two axes.

Versions for high frequencies: We can supply versions of our BH300, BH600 and BH1300 standard sets for high frequency operation, with a reduced number of turns adapted to the application of the Customer.              

Optional orthogonality to ± 0,1º:  Thanks to a new procedure for measuring the orthogonality we can offer as an option our standard and special coil-sets, of up to 600-mm in diameter, with an orthogonality error < 0.1º, or even less in some cases. To know more about this topic two PDF documents can be get by these links:  NAS03-i   and    NAS04-i             

PBH1300-P/R-1

Supporting stand for BH1300-xx. To place the coil-set at a comfortable height. That also reduces the distorting effect due to the iron, or steel, what could be located under the floor surface.

We also supply alternatives for coils of other dimensions.

Stands for Device Under Test, for standard coil-sets and special ones.

Stands for 3D magnetic mapping

These allow to place a probe in the X/Y/Z space with a precision of ±1 mm, for the study of the magnetic field homogenity.

Its design is adaptable to different coil dimensions.

Air-bearing, non-magnetic, rotating stand for device under test, well suited for picosatellites.

DUT Stand

for BHC2000-3-A/B

Stands for Device Under Test, for sets of 2 metres.

Elevated flooring

for BHC2000-3-A/B

Flooring modules, for sets of 2 metres.

DUT stands for

 BH300-3-A and BH300HF-3-A

BH300-DUTST-1

BH300-DUTST-1B

Economical stands for devices under test, for sets of 300-mm.

 Applicación Note about the definition of field homogeneity  - Click here -

All the coils are made robust but with a reasonable weight, with proven non-ferromagnetic materials and accurately. In all cases the produced field by the Helmholtz pairs is less than 1% off the theoretical value.
