Liquid-level switches used in aircraft, nuclear-power plants, medical equipment, and other critical applications must be precise and reliable. For that to happen, design engineers must know the ...

Sometimes we need a non-contact liquid level sensor. There are several ways to build that, but the easiest is to try an optical liquid level sensor. You may already have an idea in mind since you are ...

In most applications, level measurements need to be quantified and sent electronically to an automation system, which requires some type of instrument. Sorting through the instrument selection process ...

They do so by sending a small current through their probe tip. Current flowing between the sensor and some reference (often the metal tank holding the liquid) is compared inside the sensor to current ...

When designing a system, one of the most important design decisions is choosing what voltage domain(s) to use. Some voltage domains, such as 5 V, are good for noisy and harsh operating environments ...
