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.
