In
comparison to our popular DP-049
in-situ dilution extractive probe, the ESP-050
probe is more desirable for applications where either a
source-level analyzer is to be used, or where the sample
gas concentrations to be monitored are already in a low
range (and an ambient-level analyzer is to be used). Since
there is no "diluting aspirator" built into the
ESP-050, any moisture present in the sample stream will
not be reduced to levels below the dew point. Originally
designed for "hot/dry" gas applications, the ESP-050
can be fitting with a heated sample line (by customer) to
prevent sample condensation due to low ambient temperatures.
ASI also has designed and developed an optional probe heater,
for the more challenging in-situ applications where source
moisture and probe-filter fouling are a concern. The optional
probe heater may also be used where strong variations of
the process temperature, and consequently of the probe,
may be expected. As there is no diluent motive air to accelerate
the sample flow rate to the analyzer, special attention
should be paid to sample line length (to the analyzer),
to ensure that any sample delay time requirements are met.
