Loop powered Moisture Analyzer , Dew Point Transmitter , Range -110℃ dp to +20℃ dp

DPT 820

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
atmosphericpressurebyallowingthesample celloutlet(exhaust)port toventwithoutrestrictions
