PSG Plus Extruded Flex: heated sample line with a very small bending radius
The PSG Plus Extruded Flex is developed for continuous extractive gas analysis in situations that require a small bending radius. 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, gas components are not washed out and the analyser keeps working reliably, even at outdoor temperatures down to -20 °C.
Application
The PSG Plus Extruded Flex is ideally suited for installations with little space for bends or turns, such as switch cabinets, analyser cabinets or complex pipe routes. The line combines the heating performance of the PSG-Plus cable with the flexibility made possible by the integrated plastic spring wire in the jacket.
Technology
The line has a thick-walled extruded outer jacket of TPU, PE or PVC, flame-retardant and extremely weather-resistant, reinforced with a plastic spring wire for the small bending radius. Heating is provided by the high-grade PSG-Plus parallel heating cable. Isolatie is uitgevoerd met glasvezel- of thermisch vlies. Inner tubes of PTFE, PFA, stainless steel or special alloy are available, optionally replaceable.
Functions and options
The line is available up to 300 metres on a cable reel 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.
