Properties
Application
The controlled heated flexible sample lines series PSG Basic Flex are used for continuous extractive gas analysis. They serve primarily for the transport of the humid sample gas stream from the sample point to the analyzer house. The holding temperature of the line thereby has to be above water vapour resp. acid dew point of the sample gas. In this way uncontrolled condensation of water vapour on the way to the analyzer and therefore washing out of gas components in condensate is prevented. Also, failure of the measurement by a freezing line at ambient temperatures below 0°C is avoided.

Technology
The flexible lines are equipped with outer jacket corrugated tube made of PA12. The ultra-flexible versions get an outer jacket made of PA12 braid. For heating a fixed resistor heating cable is used. Insulation is done with silicone foam hose. Up to 6 internal lines made of PTFE or PFA are possible. Interchangeable PTFE or PFA are also available.
Functions
The lines are delivered completely assembled and ready for operation ex works. The control of the lines is done with an external temperature controller (e.g. Controller ST 49 or Controller DC-10) via integrated PT100 to max. 200°C.
