Application
The heated gas sampling tubes series PSG HT 250 are 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.
