Adjective
magnetostrictive (comparative more magnetostrictive, superlative most magnetostrictive)
Relating to, or caused by magnetostriction
Early WW2 losses prompted rapid research in the field, pursuing both improvements in magnetostrictive transducer parameters and Rochelle salt reliability. Source: Internet
In 1940, the US sonars typically consisted of a magnetostrictive transducer and an array of nickel tubes connected to a 1-foot-diameter steel plate attached back to back to a Rochelle salt crystal in a spherical housing. Source: Internet
The later Type 3, with German-design magnetostrictive transducers, operated at 13, 14.5, 16, or 20 kHz (by model), using twin transducers (except model 1 which had three single ones), at 0.2 to 2.5 kilowatts. Source: Internet
The piezoelectric Rochelle salt crystal had better parameters, but the magnetostrictive unit was much more reliable. Source: Internet
The required dimensions were too big for ADP crystals, so in the early 1950s magnetostrictive and barium titanate piezoelectric systems were developed, but these had problems achieving uniform impedance characteristics and the beam pattern suffered. Source: Internet
The SQS-23 sonar first used magnetostrictive nickel transducers, but these weighed several tons and nickel was expensive and considered a critical material; piezoelectric transducers were therefore substituted. Source: Internet
