Signal conditioning products provide amplification, filtering, converting, and other processes required to make sensor outputs suitable for reading by computer boards. Signal conditioning products are used primarily for data acquisition, in which sensor signals must be normalized and filtered to levels suitable for analog-to-digital conversion so they can be read by computerized devices. Signal conditioning type, form factor, device specifications, signal inputs, sensor inputs, specialized inputs, transducers and excitation, outputs and user interface are important parameters to consider when searching for signal conditioning products Other specifications to consider when selecting signal conditioning products include application, software, memory and storage, network specifications, filter specifications, amplifier specifications, and environmental parameters.
