We can stop right here. Daniel, you have sent this message to an
entire mailing list. There is nothing in your message that indicates
to whom or to what you are responding.
There is nothing in your message more than what's really obvious, to
anyone who reads the documents, and some of us read all this months ago.
By the way, looking at this manual, it looks like pressure is part of
the P37AB147 and P37B147 probes, I misread the specifications in the
manufacturer's catalog and incorrectly assumed that the pressure
sensor was part of the data logger. Those probes do measure pressure.
Those probes, however, are only rated to 60 C. Galantini used the
HP474ACR probe, which measures humidity and temperature, which indeed
can handle 150 C. It is not clear that it can actually measure
temperature at that level.
The device is designed for the monitoring of indoor air quality. This
explains why Galantini would have access to one of these,
environmental testing is his business. There is no sign that he or
his business have any expertise in steam engineering. He is a chemist.
The manual makes clear that the "g/m^3" is a displayed humidity
value. It is simply Absolute Humidity. The sensor is a plastic
material that can take in water vapor. But not liquid water, so it
only measures the vapor phase.
For convenience, here is the rest of your post.
There is the probe and there is the instrument itself. The
instrument itself just responds to whatever analogical electric
signals the probe sends. And it is basically a calculator and makes
stores this signuals The instrument is called
***HD37AB134***
MANUAL:

and you are talking about the validity ranges of the probes
****P37AB147*** and the ****P37B147*****
The instrument can be connected to ****A LOT OF DIFFERENT PROBES***
which, among them, includes (PAGE 64, you can see the list of all
probes supported)
**** HP474ACR****
which goes up to 150C.
It is even stressed that the probes are ordered separately.
