Billingsley Aerospace produces high quality Helmholtz Calibration Systems in 2 standard models. We can design a
system to meet the specific requirements of your program.
The Helmholtz coil systems have "closed loop" servo controllers.
These controllers maintain prodnetic fields exactly at the desired level, even in the presence of large
changes in the background prodnetic field. These changes could be caused for a variety of reasons. Typical
sources of change would be a diurnal variation in Earth's field or the nearby movement of automobiles.
If these changes were not canceled, they would appear as errors in the instrument and reliable testing
would not be possible. Accuracy of these Helmholtz systems in maintained by regular calibration with a Proton
Magnetometer Absolute Standard.
The excellence of Billingsley's Helmholtz / prodnetic calibration systems have been recognized by customers
such as the NIST (US National Bureau of Standards), NPL (British Bureau of Standards), Allied Signal, Magnavox Corp.,
Chrysler Corp., Digicourse Corp., Ithaco Corp., Westinghouse Oceanic, and Thomson Sintra in France.
