Description
The controlled heated flexible sample lines of the PSG Flex Plus series are used for the continuous analysis of extractive gases. They are mainly used to transport the wet sample gas stream from the sampling point to the analyzer house. The holding temperature of the line must therefore be higher than the water vapor or acid dew point of the sample gas. This prevents uncontrolled condensation of the water vapor on the way to the analyzer 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 flexible lines are equipped with a corrugated tube with a metal outer sheath. A fixed resistance heating cable is used for heating. The insulation is made of glass fibre and thermo-fleece. Internal lines in PTFE or PFA are possible. Pressure resistance is achieved by a braided metal sheath of the inner tube.
The lines are delivered fully assembled and ready for operation ex works. The lines are controlled with an external temperature controller (e.g. PSG ST49 or PSG DC10) via an integrated PT100 up to max. 200°C.
