Properties
Application
The controlled heated sample lines series PSG Basic Extruded 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 robust lines with thick-walled extruded flame resistant and extremely weather resistant TPU, PE or PVC outer jacket are equipped with parallel heating cable. Insulation is done with a thermal or glass fibre fleece. Up to 12 PTFE, PFA, stainless steel or special alloy tubes as internal line and also interchangeable internal tubes are available.
Functions
The lines are available up to 300m at a stretch e.g. on cable drum and then can be adapted on-site and shortened every 0,5m. Furthermore, they are available ready for operation ex works. Control of the lines to max. 200°C is done by an external temperature controller (e.g. Controller ST 49 or Controller DC-10) via the integrated PT100.
