PSG Plus Extruded ATEX 180: controlled ATEX sample line up to 180 °C
The PSG Plus Extruded ATEX 180 is developed for continuous extractive gas analysis in potentially explosive environments that require a holding temperature of up to 180 °C. 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 (solutions down to -52 °C on request).
Application
The PSG Plus Extruded ATEX 180 is suitable for use in Ex zones 1 and 2 in the chemical and petrochemical industries, power plants, the steel industry and other process environments where higher holding temperatures combined with ATEX certification are required. The line offers 30 °C more holding temperature than the ATEX 150-variant, which may be necessary for gas streams with a higher acid dew point.
Technology
The line has a thick-walled extruded outer jacket of TPU or PVC, flame-retardant and extremely weather-resistant. Heating is provided by a high-grade Ex heating cable of 60 W/m with a maximum cable temperature of 250 °C. Isolatie is uitgevoerd met glasvezel- of thermisch vlies. Inner tubes of PTFE, PFA, stainless steel or special alloy are available, optionally replaceable. The electrical connection is via a M25-kabeluitgang to an ATEX junction box.
Functions and options
Temperature control up to a maximum of 180 °C is via an external temperature controller with limiter via the integrated PT100-sensor (e.g. FRBL1 with SSR or NGC-20-CL-E). The line is available up to 300 metres on a cable reel and can be cut every metre on site without loss of function. Ready-made lengths ex works are also possible.
