Conclusions
-
1.
A technique for evaluating the intrinsic temperature errors in external gauges of process control instruments has been suggested and developed.
-
2.
It has been shown that temperature variations of fixed dimensions in a gauge have a complicated characteristic and depend substantially on the nature of the ambient-medium temperature variations and on the design of the gauge.
-
3.
In developing process control gauges it is necessary to aim at providing equal temperature inertia constants for the basic gauge components which affect the fixed dimension.
