Depending upon the distance between the surface of a capacitance probe and a target source, the electrical capacitance that is formed between these two objects will vary. In an effort to improve ...

This paper describes the design and characterisation of a long-range capacitive displacement sensor, NanoSensor® model NXE2. Special emphasis is placed on the design features and metrological ...

Capacitive displacement sensor’s touch-free nature makes it ideal for fragile surfaces and high-speed machinery.

Engineers usually have access to signal and function generators, as well as frequency counters and oscilloscopes, but they may not have access to capacitance or inductance meters. Using the test setup ...

Viable cell count (VCC), a critical parameter in both microbial and mammalian cell cultures, fluctuates during batch and fed-batch cultures. VCC is determined conventionally through sampling and ...

Capacitive sensing is a contactless-sensing technique with numerous applications, ranging from proximity sensing (Fig. 1), gesture recognition, automotive rain sensors, and remote liquid-level sensing ...

Proximity sensors detect objects without physical contact. Most proximity sensors emit an electromagnetic field or beam and look for changes in the field. The object being sensed is called a target.

A frequent beginner project involves measuring soil moisture levels by measuring its resistance with a couple of electrodes. These electrodes are available ready-made as PCBs, but suffer badly from ...

Semiconductor testing has traditionally functioned as a stable screening step in the manufacturing flow so that failing ...

For decades, the venerable 10:1 passive scope probe has connected innumerable signals and scopes to each other. And, when neither the probe’s nor the scope’s performance limitations are exceeded, the ...
