发明名称 Method to obtain a temperature coefficient-compensated output signal in an optical current measuring sensor
摘要 In a magneto-optical sensor with -/+ intensity norming, the temperature-coefficient-compensated output signal (S) is obtained by formation of a quotient of the alternating portion (PAC) of the intensity-normed signal (P) and a function (f(PDC, PACeff)), determined by a calibration measurement, of a direct portion (PDC) of the intensity-normed signal (P) and of a root-mean-square value (PACeff) of the alternating portion (PAC). A corresponding method for sensors with AC/DC intensity norming is indicated.
