Gas sampling and gas conditioning technology 2-1.1.6.1-ME
Depending on the process gas temperature and composition, probe tubes made of different
materials are used with ¾" connections:
Material Type Process temperature max. length Pipe (nipple) o.d.
Stainless steel 316 SS up to max. 600 °C 2,5 m 25 (37)mm ø
Titan Ti up to max. 400 °C 2,5 m * 25 (37)mm ø
Hastelloy Ha up to max. 900 °C 2,5 m * 25 (37)mm ø
Incolloy 956 In up to max. 1200 °C 2,0 m * 25 (37)mm ø
Kanthal Ka up to max. 1300 °C 2,5 m * 25 (37)mm ø
Alu. oxide AO up to max. 1800 °C 1,5 m * 25 (55)mm ø
PVDF PV up to max. 90 °C 1,5 m * 25 (37)mm ø
PTFE T up to max. 160 °C 0,5 m 33 mm ø
1m standard *
Depending on the process gas temperature and composition or critical set up situations,
heated probe elements made of stainless steel with flange connection DN65 PN6 are used:
Type Process temperature max. length Pipe o.d.
SP30H1, heating max. 320°C up to max. 550 °C 2,0 m * 40mm ø
SP30H2, heating max. 200°C up to max. 200 °C 2,0 m * 40mm ø
SP35H, heating max. 320°C up to max. 550 °C 0,175 m 40mm ø
1m Standard *
In case of higher dust loadings of the process gas, by all means we recommend using a prefilter in
order to prolong service life. This can be supplied with or without dead volume displacer depending
on the response times required. These filters can be screwed directly into the probe flange or via ex-
tension tubes fitted with volume displacers (see Fig.10).
We recommend the following prefilters with ¾" connection:
Dust loading Prefilter Type Process Temperature Prefilter o.d.
