The fluxgate magnetometers on the ISEE 1 and 2 spacecraft are described. Special features include 12-bit analog-to-digital conversion plus averaging to return 16-bit overlapped averages with a particularly attractive transfer function. Flippers activated by bimetallic heaters enable frequent sensor interchange into the spin plane to monitor instrument drifts. Initial operations have been entirely successful.
