Single-ended capacitance probes or ‘push/pull’ capacitance sensors can be used for this specific application to monitor the distance between probe and rotor while spinning. When a push/pull sensor is ...

The main environmental consideration for a capacitive sensor is that there is a uniform, nonconductive material between the target and the sensor. In most applications, this material is air. However, ...

Thus more-than-typical interest in inline capacitance probes, which distinguish living cells from “everything else” by the capacitance changes objects induce in the probe as they interact with it.

Instead, the input capacitance is the sum of the cable capacitance and the scope’s input capacitance—for example, the Tektronix P6101B 1:1 2-m probe has a 15-MHz bandwidth and 100-pF input C.

A capacitive sensor includes a capacitive probe, an oscillator, a signal rectifier, and an output circuit (Fig. 4). 4. This illustration shows the anatomy of a capacitance proximity sensor ...

A bipolar-transistor probe may load a circuit with only a 0.7-pF capacitance, and it has a high-input impedance-generally in the range of 100 kV, or greater. The low capacitance is particularly ...

[Marcus] has written up his experiences using the AD7746 capacitance sensor. He used the SparkFun breakout board in conjunction with an Arduino. The available Arduino code wasn’t that great s… ...
