Active probes do not use signal power from the DUT, but alternatively utilize wideband amplifiers to enable high-frequency measurements. Active probes have high input resistance and low capacitance, ...

Detection and control of the level of liquid in a reservoir is another suitable application, as Cx increases because rising liquid level increases capacitance between the liquid and an insulated probe ...

Non-contact sensors using capacitive and eddy-current technologies each represent a unique blend of advantages and disadvantages for a variety of applications. This comparison of the two technologies’ ...

Abstract: Real-time monitoring of heat loads in cryogenic systems is critical for many applications, particularly high field magnets. We demonstrated that by monitoring changes in the capacitance of ...

The probe can be enclosed in a protective cap in these more demanding locations to protect the sensing mechanism from unforgiving surroundings. In this case, a simple, constant offset adjustment will ...

Capacitive sensors measure quickly. They are ideal for high-bandwidth measurements applications and high-volume sorting applications. The capacitive sensor offers a very high resolution, matched only ...

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 ...
