In engineering and scientific fields, “signals” typically refer to a function that conveys information through variation with respect to some independent variable, most commonly time. The function’s values can represent physical quantities such as voltage, current, light intensity, sound pressure, or electromagnetic field strength. Analog Signals An analog signal is one that varies continuously in […]

1. Overview In modern chemical and process industries, corrosion remains one of the most critical challenges affecting production stability, instrument reliability, and plant safety.Pipelines, flowmeters, level transmitters, and process sensors are exposed to a wide range of acids, alkalis, solvents, and gas–liquid mixtures, many of which may chemically attack wetted materials. Understanding the corrosive properties
