Properties
Application
The heated gas sampling tubes series PSG HT 250are used for continuous extractive gas analysis. They enable trouble-free representative sampling of hot predominantly dust and water vapour loaded gases. Typical applications are emission measurement, process monitoring and process optimization.
Technology
The intelligent design of the double jacket tube with homogeneous controlled heating to 180°C over the entire tube length enables a trouble-free extraction of sample gas without condensate formation. The mounting flange with stud bolts on both sides (DN65PN6) enables a seamless adaption to the gas sampling probes PSG Basic Probe und PSG Plus Probe as well as to the process flange DN65PN6. For other process flange dimensions adapter flange connectors are available. Apart from the standard PT100 temperature sensor, thermocouples of type J (Fe-CuNi) or K (NiCr-Ni) are also possible.
Functions
Due to homogeneous heating to 180°C, zones are bridged where temperature is possibly falling below the dew point resp. acid dew point of the sample gas on its way from sampling point to gas sampling probe. Thus, condensate formation and therefore blocking and damaging of the tube as well as washing out of water-soluble sample gas components like SO2 is prevented. With optional G3/4“-internal thread at the tube end the heated gas sampling tube PSG HT 250 can be extended with all unheated sampling tubes and pre-filters from the PSG product range.
