用于电容性逼近检测的传感器装置及方法
摘要：
本发明涉及用于电容性逼近检测的传感器装置及方法。该装置包括：电极系统，电极系统包括：第一发射电极及第一接收电极，其中可使第一发射电极与第一接收电极电容性耦合；以及-第二发射电极及第二接收电极，其中可使第二发射电极与第二接收电极电容性耦合；-信号产生器，其用于给第一发射电极馈送第一电交变信号且给第二发射电极馈送第二电交变信号；及-信号处理装置，其与第一接收电极且与第二接收电极耦合，且其适于从在第一接收电极处分接的第一电值与在第二接收电极处分接的第二电值之间的差形成第一测量变量。本发明还涉及一种用于借助根据本发明的电容性传感器装置对物件进行逼近检测的方法。
摘要（英）：

The invention relates to a capacitive sensor device, comprising an electrode system, comprising a first transmitting electrode and a first reception electrode, wherein the first transmitting electrode can be brought into capacitive coupling with the first reception electrode, and -a second transmitting electrode and a second reception electrode, wherein the second transmitting electrode can be brought into capacitive coupling with the second reception electrode, -a signal generator for feeding the first transmitting electrode with a first electric alternating signal and the second transmitting electrode with a second electric alternating signal, and -a signal processing device, which is coupled with the first reception electrode and with the second reception electrode, and which is adapted to form a first measurement variable from the difference between a first electric value tapped at the first reception electrode and a second electric value tapped at the second reception electrode. The invention also relates to a method for the approximation detection of an object with a capacitive sensor device according to the invention.
