Description
The controlled heated sample lines of the PSG Extruded basic series are used for the continuous analysis of extractive gases. They are mainly used to transport the wet sample gas stream from the sample point to the analyser house. The holding temperature of the line must therefore be higher than the water vapour or acid dew point of the sample gas. This prevents uncontrolled condensation of the water vapour on the way to the analyser and thus the washing out of the gas components in the condensate. Measurement failure due to a freezing line at ambient temperatures below 0°C is also prevented.
The robust lines with thick-walled, flame retardant TPU, PE or extruded PVC outer sheath are equipped with a parallel heating cable. The insulation is made of thermal fleece or fiberglass. Up to 12 PTFE, PFA, stainless steel or special alloy tubes as inner line and also interchangeable inner tubes are available.
The lines are available up to 300 m in a row, e.g. on a cable reel and then adaptable on site and shortened every 0.5 m. In addition, they are available ready for operation from the factory. Control of the lines to max. 200 ° C is carried out by an external temperature controller (eg PSG ST49 or PSG DC10) via the integrated PT100.
