continuous, monitoring, online, process, quartz crystal
AMETEK model is an analyzer that measures the moisture on-line by monitoring the vibrational frequency change of a hygroscopically sensitized quartz crystal that is exposed alternately to wet sample and dry reference gas for 30 second periods. Calibrated 0 to 1000 ppm by volume and display continues to provide trend information above 1000 ppmv. The output capability in lb/mmscf and dew point requires sample line pressure as analog input; single point systems only. It is applicable to use in petroleum refining, petrochemicals, and among others.
