PSG Plus Extruded Duo: heated sample line with dual outlet
The PSG Plus Extruded Duo is developed for continuous extractive gas analysis where a heated split is needed at the end of the line. The line transports the humid sample gas from the sampling point to the analysis room at a constant temperature above the dew point and acid dew point. This prevents condensation of water vapour on the way and gas components are not washed out in the condensate.
Application
The PSG Plus Extruded Duo is mainly used with mercury analysers and with systems that work both cold-extractive and hot-extractive. The heated split at the end of the line makes it possible to serve two analysers with one probe, or to keep calibration lines at temperature continuously. The split can be applied on the sampling side, the analyser side or on both sides. All combinations are possible.
Technology
The line has a thick-walled extruded outer jacket of TPU, PE or PVC, flame-retardant and extremely weather-resistant. Heating is provided by the high-grade PSG-Plus parallel heating cable (type CPD Plus). The insulation consists of thermal fleece. Thanks to the matched insulation in the two outgoing sample lines, one temperature sensor at any point in the line is sufficient to control the entire installation.
Functions and options
The line is available up to 73 metres in one piece and can be cut every 0,6 metres on site without loss of function. Ready-made lengths ex works are also possible. Temperature control up to a maximum of 200 °C is via an external temperature controller (e.g. PSG Controller ST49 or DC-10) via the integrated PT100-sensor. The two heated outlets at the end of the line are available in lengths of 60, 120 or 180 cm, combinable on request.
