The model 720 is a low-cost, compact capacitance vacuum gauge (CVG) based on the companyÕs variable capacitive sensor design. It produces a 0 to 5 Vdc or 0 to 10 Vdc output that is linear with ...

Often, it's necessary for a sensor system to compute the ratio of two capacitors. Doing so re-duces the transducer's sensitivity to dielectric errors from such ...

In a way, the magic of a soil moisture sensor’s functionality boils down to a simple RC circuit. But of course, in practice there is a bit more to it than that. [rbaron] explains exactly how ...
