A method for measuring the humidity of gases by resistance grid dew-point sensor is reported. The principle of measurement is described. The sensor can transform humidity signals into switch resistance values automatically. The resolution and precision of the sensor are very high. The resistance will be changed from infinity to a definte vaiue when there is trace water in gas. The instrument can also be used for measuring the thickness of water membrane.

The principle of α ray dew point transducer was introduced and the α ray dew point transducer consisty a semiconductor detector and a temperature transducer. The output characteristics of the transducer were examined. It is found that the response of the transducer is non linear and the transducer suffers from the influence of over a wide measuring range by femperature. A method for temperature tracking compensation of dew point voltage transducer based on artificial conjugate gradient optimum algorithm for nerve network was presented. In order to realize temperature compensation over the full range,the neural network is trained to represent the nonlinear mapping properly between transducer reading and their represent output accurately at different temperature. It is revealed from the computer simulation that not only the influence of temperature fluctuation can be eliminated effectively,but also a desired linear relationship between the transducer input and the neural network output can be obtained.
