Conclusions
-
1.
A concept has been formed for describing the modulation depth of the physical characteristic used in instrument transducers by the information about the tested parameter.
-
2.
A generalized resolution criterion has been proposed for selecting the physical characteristic of the process and the method for measuring it, which have an optimum efficiency for controlling the process.
-
3.
The results of applying the generalized resolution criteria in analyzing instrument transducers of a device for testing continuously the concentration of a catalyzer in oil produce vapors are provided.
