Signal Conditioning

What is Signal Conditioning?

Signal conditioning, with respect to process monitoring and control engineering applications, is the practice of preparing a raw input signal for use with instrumentation in a data acquisition and/or control system. The signal conditioning process typically involves one or more of the following steps: isolating, filtering, amplifying, and converting a sensor input signal to a proportional output signal that is transmitted to another control device or system. Sometimes a signal conditioner can perform computation functions such as totalization, integration, pulse-width modulation, linearization, and other math operations on a signal.

Common industrial signal conditioners accept voltage, current, frequency, resistance, or strain gauge input types. Acromag's various signal conditioning instruments are categorized as process transmitters, signal isolators, math/computation modules, panel meters, and remote I/O modules.
