SQ250 FLK Gas Sampling System
2.7 Compressed air connection
The connection point for the compressed air line should be positioned at the same height as the venting containers, but on the
opposite side of the probe. The compressed air line NW20 (length 3.5m) with DIN 3483 hose couplings at both ends must be
used for the connection from this supply point to the valve combination. At the supply point the compressed air should
preferentially be implemented by the customer in 1/2" pipe. A threaded coupling R 1/2" with metal seal as counter piece to
the hose coupling is supplied for the transition to this feed line.
2.8 Measuring gas connection
The measuring gas connection from the valve combination to the connection point (the centre of the retraction device) is
implemented using a 3.5m long PTFE pressure hose of NW8 with metal braiding ( 2 ) and M16x1.5 union nuts at both ends.
The PTFE pressure hose is screwed onto the bulkhead screwed gland ( 1 ) which is fixed to the connection point. A hose
connection piece is fastened in the bulkhead gland, so that a PVC hose of ID 6mm ( 3 ) can be led further to the analysis
equipment. ( See Figure 5 ).
