奥础驰颁翱狈测量原理电容式传感器
WayCon电容式传感器的设计基于以下事实：理想的平板电容器的电抗与板之间的距离成比例。测量传感器是保护环电容器，其保护环连接到双屏蔽测量电缆的内屏蔽。负反馈放大器保持该保护屏蔽地调谐到传感器中心电极的电位。这确保了在整个测量范围内电容器板之间几乎均匀的场，并且几乎*独立于电缆容量的变化。如果恒定频率和频率的交流电流通过传感器电容器，则电容器板（传感器的电极和待测物体）之间的交流电压的幅度与两者之间的距离成正比。具有高恒定幅度和频率的20 kHz振荡器可提供传感器电流以及可通过精密电位计选择的补偿电压。通过低通滤波器和放大器，对输出端子进行电压差。
如距离计的操作的上述部分所述，测量受电介质的性质的影响。通常传感器将用于空气中的测量。传感器与目标之间的区域应*没有灰尘，油或水。如果需要，可以通过吹出一些空气通过传感器和目标之间的间隙来实现。

Ultrasonic sensors measure without contact the distance to the measurement object, regardless of color and material. Ultrasound is a high-frequency oscillation emitted by the sensor, which is reflected on the measurement object and is received back in the form of an echo. From the travel time of the sound, the sensor calculates an analog output signal proportional to the distance. A classic application for ultrasonic sensors is level measurement.
