10 Gas sampling and gas conditioning technology 2-1.1-ME
10 DESCRIPTION
The sample probes are designed for easy installation, reliable and flexible operation and trouble-free
maintenance. Depending on the problem, different sample tubes or prefilters (see data sheet 2-1.1.0.6
and 2-1.1.0.8) are screwed into the thread (G3/4”) in the mounting flange. This equipment is not in-
cluded in the scope of delivery of the probe.
The large-surface ceramic deep filter element (fibre glass or glass wadding fillings are also available)
is placed in a housing with small dead volume outside the process area. The probes are designed so
that no tools are necessary for changing the filter element, the sample line needs not to be dismount-
ed and no contamination on the clean gas side will occur. Cleaning or back purging of the sample tube
is possible from outside. Due to the special execution of the heating element of the SP2000-H,
SP2300-H
and SP2400-H (with protection cover), the complete filter housing including mounting
flange is heated, adjustable up to 180°C (version H320/C up to 320°C), so that a safe operation with-
out shortfall below the dew point in the out-of-process area is guaranteed. The temperature adjust-
ment of the standard version is made via an integrated capillary sensor thermostate with exess tem-
perature limiter and alarm function in compact configuration. Calibration gas feeding and comparison
sampling at the probe are possible.
Depending on the gas composition, it may be possible that the standard material of the probe body
(stainless steel 1.4404) is not sufficient with respect to ist corrosion resistance. For this case, the
SP2300-H
of PTFE is available or alternatively for a heating above 180°C the SP2400-H out of Titane.
