Sample gas inlet conditions

Sample gas flow

1 × 250 l/h (WT250) or 1 × 125 l/h (WT125) or 2 × 125 l/h

(WT125), based on a sample gas pressure of pabs =

100 kPa (1 bar) and 25 °C

Note

Only the WT125 is used in the AO2000 system

Sample gas inlet temperature

• Standard design: maximum 140 °C

• CSA Class I, Division 2 design: maximum 135 °C

• ATEX Zone 2 design: maximum 130 °C

Sample gas inlet dew point

max. 70 °C,

max. 60 °C for WT250 with sample gas flow > 200 l/h
