8.5.4 Using the Linearization Block
The example in Figure 8-21 shows a typical use of a Linearization Block. The analog input
signal is from a differential pressure transmitter measuring flow. The type field of the
linearization block is set at MOD SQRT. The block extracts the modified square root of the
continuous signal from the transmitter.
