What are the Stages of Signal Conditioning?
Signal conditioning consists of several stages to ensure that signals from sensors or transducers are accurate, reliable, and suitable for further processing. These stages are signal acquisition, amplification, filtering, isolation, linearization, conversion, modification for specific applications, and output signal transmission. Signal acquisition is when the conditioner receives the initial signal from a sensor or transducer. Then, the signal is amplified, increasing the strength of weak signals so they can be better processed. After amplification, filtering removes unwanted noise and frequencies from the signal so only relevant info is used. Next, isolating the input and output signals prevents ground loops and protects equipment from high-voltage surges. Linearization is then performed to correct nonlinear signals and produce a linear output that accurately represents a measured quantity. Now the signal can be converted and tailored to match the input requirements of the application. Lastly, the signal is prepared for output by ensuring it is in the proper format and is within the acceptable range for processing, display, or control.
Acromag provides signal conditioners that incorporate these stages to ensure accurate and reliable signal processing in various industrial applications. Products like the TT Series of transmitters offer robust functions, designed for use in harsh environments.
