Sensor Operating Principle
The nanopore sensor utilized in this analyzer measures the amount
of water vapor molecules that have entered its pores.This amount is
directly proportional to the partial water vapor pressure in the
gas surrounding the sensor,and the partial water vapor pressure is
dependant on the water vapor content of the gas and the total
pressure of the gas,Thus to compute the water vapor content of the
gas under measurement the analyzer has to “know”the total pressure
of the gas.Since there is no built-in pressure sensor,the user
should enter the total pressure into the analyzer,this can be
easily done by entering atmospheric pressure(the analyzer default
setting)and measuring at atmospheric pressure by allowing the
sample cell outlet(exhaust)port to vent without restrictions.
