Dewpoint Measurement (pressure vs. ambient)
Dewpoint Measurement (pressure vs. ambient)
(OP)
I realize when most people talk about the dewpoint of their instrument air they are assuming the dewpoint measurement was made at line pressure. This is the pressure dewpoint.
I currently have our dewpoint analyzers set up to measure the dewpoint at very low pressure, then I do the conversion to pressure dewpoint. I do this because I figure there is less risk of sending liquid water (during an upset) to the dewpoint probe.
Does this seem appropriate, or will measuring the dewpoint near ambient pressure not produce accurate results? I appreciate any helpful input.

PS : As low pressure air always holds more moisture, we dry it when it is compressed for energy optimisation.
