Drift stabilized magnetoelastic force transmitter

摘要

driftstabilisierter magnetoelastischer kraftgeber one has with facilities for excitation and signal processing. according to the invention is a bezugsgeber (1) available from the same material as the has is with the detecting device has good thermal contact is arranged such that both have the same or approximately same temperature donors.the erregereinrichtung is so arranged that the speisestrom by bezugsgeber in every moment proportional to the speisestrom by has. the bezugsgeber carries a winding to provide a bezugssignals, which is proportional to the magnetic flux.the bezugssignal during a eichintervalls to a phase sensitive rectifier connected in alignment. the phase sensitive rectifier is connected a control voltage.the output signal of the market is in the entrance of a differenzgenerators user, whose second input is connected to a reference of a bezugsspannungsquelle.the output signal of the differenzgenerators is connected to links to control the ausgangssignals of phase sensitive market by controlling the phase of the output voltage in such a way that the output signal is equal to the reference.the output signal of the meu00dfgebers is a phase sensitive rectifier during a meu00dfintervalls connected with this...
