Abstract
The possibility of using algorithms for predicting transients in measurement instruments is considered, in particular, in dissolved oxygen analyzers, instruments used for measuring mass concentrations in the microgram range. The objective that is set forth is to reduce the time taken to evaluate oxygen concentration during a transient from high to low concentrations. A signal processing algorithm is proposed using which it is possible to produce a new transient for obtaining current oxygen concentration values that converge to their steady values within a shorter period of time. The effectiveness of the proposed algorithm is studied taking as an example three typical sensors having significantly different response times. It is shown that for relatively slow sensors the transient in which may last for a few hundreds of seconds, an essentially shorter (by up to a factor of 2) duration of measurement procedure can be achieved.
