    • A sensor arrangement comprises a first sensor element for converting a physical quantity into a first electrical signal and at least a second sensor element for converting said physical quantity into a second electrical signal. The first sensor element has a first sensitivity while said second sensor element has a second sensitivity different from said first sensitivity. The first sensor element is operatively coupled between terminals of said sensor arrangement and said second sensor element is operatively connected between said terminals of said sensor arrangement via a temperature controlled switching element so that in a first state of said temperature controlled switching element, said second electrical signal combines with said first electrical signal to form a sensor output signal, and in a second state of said temperature controlled switching element, the contribution of said second electrical signal to said sensor output signal is substantially reduced with respect to a respective contribution in said first state of said temperature controlled switching element.
    • 传感器装置包括用于将物理量转换为第一电信号的第一传感器元件和用于将所述物理量转换成第二电信号的至少第二传感器元件。 第一传感器元件具有第一灵敏度,而所述第二传感器元件具有与所述第一灵敏度不同的第二灵敏度。 第一传感器元件可操作地耦合在所述传感器装置的端子之间,并且所述第二传感器元件经由温度控制的开关元件可操作地连接在所述传感器装置的所述端子之间,使得在所述温度控制的开关元件的第一状态下,所述第二电 信号与所述第一电信号组合以形成传感器输出信号,并且在所述温度控制的开关元件的第二状态中,所述第二电信号对所述传感器输出信号的贡献相对于所述第一电信号的相应贡献大大减小 所述温度控制开关元件的状态。
