PSG Plus Extruded ATEX 150: controlled ATEX sample line up to 150 °C
The PSG Plus Extruded ATEX 150 is developed for continuous extractive gas analysis in potentially explosive environments that require a holding temperature of up to 150 °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 150 is suitable for use in Ex zones 1 and 2 in the chemical and petrochemical industries, power plants and other process environments where a holding temperature of 150 °C combined with ATEX certification is required. The line is an alternative to the ATEX 180-variant when 150 °C is sufficient for the specific application.
Technology
The line has a thick-walled extruded outer jacket of TPU or PVC, flame-retardant and extremely weather-resistant. Heating is provided by the Raychem® 40FHT2-CT heating cable, which can handle maximum cable temperatures of up to 260 °C and enables a holding temperature of up to 150 °C at -20 °C ambient temperature. 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 150 °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 1,5 metres on site without loss of function. Ready-made lengths ex works are also possible.
