EFFECT OF MEASUREMENT DYNAMICS
Measurements provide the window into the process. Smart transmitters have made the view clearer. Installation and operating condition effects are compensated for enabling the transmitter to have an installed accuracy close to the sensor capability. The main remaining considerations are sensor nonidealities such as drift, lag, noise, rangeability and threshold sensitivity and discontinuous updates from analyzers and to a lesser extent from wireless devices. The transportation delay in getting the process to the sensor also needs to be accessed and minimized.
Filters from signal processing and transmitter damping adjustments have an effect similar to the signal filters in ...
