Presentation

The controlled heated flexible sample lines of the PSG Flex Basic series are used for continuous analysis of extractive gases. They are primarily used to transport the wet sample gas stream from the sampling point to the analyzer's home. The maintenance temperature of the line must therefore be higher than the water vapor resp. acid dew point of the sample gas. In this way, the uncontrolled condensation of the water vapor on the way to the analyzer and therefore the washing of the gas components in the condensate is prevented. Failure of the measurement by a freezing line at ambient temperatures below 0 ° C is also avoided.

The flexible lines are fitted with a corrugated pipe with an outer sheath of PA12. The ultra-flexible versions have an outer sheath in PA12 braid. For heating, a fixed resistance heating cable is used. The insulation is done with a silicone foam pipe. Up to 6 internal lines in PTFE or PFA are possible. Interchangeable PTFE or PFA are also available.

The lines are delivered fully assembled and ready to operate ex works. Line control is done with an external temperature controller (eg PSG ST49 or PSG DC10) via integrated PT100 up to max. 200 ° C
