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 contentof 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 celloutlet(exhaust)port
to vent without restrictions.
