What Is a Signal Conditioner?
A signal conditioner is a device designed to modify signals from sensors and various types of equipment to meet specific requirements.
This device adjusts the characteristics of signals that are not immediately suitable for measurement or processing. It alters levels, frequency ranges, voltages, currents, and other aspects to convert these signals into forms that are more suitable for further measurement or processing.
The functioning of a signal conditioner can be categorized into three main areas: level conversion, frequency conversion, and format conversion. Level conversion involves adjusting the signal level using operational circuits like amplifiers. Frequency conversion changes the signal’s frequency range through circuitry such as filters. Format conversion transforms the signal’s format, for instance, converting analog signals to digital signals using analog-to-digital converters. Signal Conditioners are widely used in diverse fields, including industrial measurement in production facilities, medical diagnostics like electrocardiograms and electroencephalograms, voice and image transmission in communication equipment, and the control systems of robotic operations.
