Capacitive Sensors

If the plates are close compared to the plate spacing, the calculation in Fig. 1 is accurate. But as the plate spacing increases relative to area, more flux lines connect from the edges and backs of the plates and the measured capacitance can be much larger than calculated. Some other simple geometries are Figure 2 Disk Figure 3 Sphere C ε o ...
