Description
The heated controlled sample lines of the PSG extruded hybrid series are used for the continuous analysis of extractive gases. They are mainly used to transport the wet sample gas stream from the sample 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.
In addition, all electrical and pneumatic lines for the operation of a heated gas sampling probe can be integrated. These are back-purge and test gas lines for the supply of preheated gas, which prevents cooling or condensation in the probe, as well as the power supply and temperature sensor lines. In this way, the complete installation work for all lines is eliminated and the probe can be operated and controlled directly from the analyzer house.
The robust lines with a thick-walled, flame retardant TPU, PE or extruded PVC outer sheath are equipped with a high-quality PSG-Plus parallel heating cable. The insulation is made of thermal fleece or glass fibre. PTFE, PFA, stainless steel or special alloy tubes are available as inner line as well as interchangeable inner tubes.
The lines are available up to 300 m in a row, e.g. on a cable reel and then adaptable on site and shortened every 0.6 m. In addition, they are available ready for operation from the factory. Control of the lines to max. 200 ° C is carried out by an external temperature controller (eg PSG ST49 or PSG DC10) via the integrated temperature sensor up to max. 200 ° C.
