Description of water sensor: in most houses, water is first stored in an underground tank (UGT) and from there it is pumped up to the overhead tank (OHT) located on the roof. People generally switch ...

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 ...

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 ...

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 ...
