– Calibrating Density
What type of calibration is needed?
Two types of calibration are available for Ronan’s density gage.
1 . Single-point calibration
This requires an accurate laboratory analysis of a truly representative sample of one process density. Single-Point
Calibration is used as an alternative method when it is not physically or economically practical to vary the process
density. In these cases, a second point is estimated based on the mathematical formula for radiation
transmission/absorption.
2. Dual-point calibration
This requires an accurate laboratory analysis of truly representative samples of two process densities. Dual-Point
Calibration is preferred when the process can be varied to obtain two process densities (one at each end of the
measurement range).
Important facts to remember –
• Equipment should be running at normal environmental conditions – temperature, pressure, process
flow, etc.
• Final gage measurements can only be as accurate as your sampling and analysis technique.
• Remember to document all changes made to the factory parameters that are active in your system.
