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 ...

From guest blogger Gregory Davis: Selecting the right probe is an all-important choice when it comes to acquiring a signal. As we discussed in my last post, not all probes are created equal. Many ...

Capacitance sensing probes have been in use for a number of years in the airframe assembly industry for characterizing diameters in straight and tapered fastener holes. A new type of capacitance probe ...

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 ...

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 ...

http://www.agilent.comOver the past decades, digital designers have relied on the logic analyzer as their main tool for system validation. In recent years, faster ...

An important design objective for voltage and current probes and current monitors is to determine a signal’s characteristics without significantly affecting the signal itself. In other words, the ...

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.

Of the available on-line biomass assays, the radio-frequency impedance method (often referred to as capacitance) is generally regarded as the most robust and reliable method to monitor viable biomass ...
