METHOD AND SENSOR FOR DETERMINING THE HYDROCARBON DEW POINT IN A GAS

The method involves irradiating a condensation surface (12) with light by a transparent body (10) of a sensor, and the temperature of the surface is changed. Intensity of light reflected back from the surface into the body is determined. The actual temperature of the surface is determined during occ...

Zusammenfassung:	The method involves irradiating a condensation surface (12) with light by a transparent body (10) of a sensor, and the temperature of the surface is changed. Intensity of light reflected back from the surface into the body is determined. The actual temperature of the surface is determined during occurrence of the intensity gain of the reflected back light at a decreased temperature of the surface and/or during occurrence of intensity loss of the reflected back light at an increased temperature. The actual temperature is an output as a measure for a dew point temperature of a hydro carbon. Independent claims are also included for the following: (1) a method for manufacturing a sensor (2) a sensor for determining the hydrocarbon-dew point in a gaseous fuel (3) an application of the sensor for determining the dew point temperature of a gaseous fuel.
