    • A sensor arrangement includes, in some embodiments, a magnetostrictive element configured to output magnetic signals in response to a magnetic field. A sensor is configured to sense a value of a property of a selected object, and to provide an electrical resistance that varies in response to variations in the sensed value. The sensor cooperates with the magnetostrictive element to vary the frequency of the signals output by the magnetostrictive element based on variations of the electrical resistance provided by the sensor. A transmitter provides an alternating magnetic field to the magnetostrictive element, and a receiver picks up the magnetic signals generated by the magnetostrictive element. The frequency of the signals received is correlated with the sensor resistance, and the resistance is correlated to a value of the property sensed.
    • 在一些实施例中,传感器装置包括被配置为响应于磁场输出磁信号的磁致伸缩元件。 传感器被配置为感测所选对象的属性的值,并且提供响应于感测值的变化而变化的电阻。 传感器与磁致伸缩元件配合,以根据由传感器提供的电阻的变化来改变由磁致伸缩元件输出的信号的频率。 发射机向磁致伸缩元件提供交变磁场,并且接收器拾取由磁致伸缩元件产生的磁信号。 所接收的信号的频率与传感器电阻相关,并且电阻与所感测的特性的值相关。
