Gas Sample Dilution Probe
SP2006-H/DIL...
Application
The electrically heated M&C dilution probe
is applicable for such processes, where the
measuring procedure or the handling of the
process gas require the dilution of the sample
respectively the component to be measured.
Typical applications are the use with toxic
gases, the moisture measurement and the
emission measurement in flue gases.
The M&C dilution probe SP2006-H/DIL... is
based on the well tested M&C gas sample
probe SP2000-H. This enables the user to
adapt the probe to nearly every application,
using for example special filter techniques or
special materials.
Description
The dilution unit including the critical orifice
is mounted directly at the probe body and
therefore heated up with the probe to a sta-
ble temperature. The incorporated pre-heater
heats up the dilution gas to the probe tem-
perature. Both steps avoid that sample gas
decreases under the dewpoint. Calibration
gas enters the probe via an integrated con-
nection. The probe can be heated up to 180
°C or 280 °C. As an option a heated manual
operated 2 way ball valve is available. It is inte-
grated in the sample gas inlet and shuts off
the probe head from the process, for exam-
ple during the change of the filter element.
Additional the option ‘blow back in front of
ball valve’ via the probe flange is available.
Through an optional high flow rate check
valve /BB, which is fixed to the internal probe
area, blow back of the filter housing area and
the insitu probe tube will be done.Through
the optional high flow rate check valve /BB/F,
which is fixed to the filter housing wall, blow
back of the incorporated ceramic filter will be
done incl. the filter area and the insitu probe
tube. The optional isolation valve /I shuts off
the sample outlet from the internal filter area.
To optimize the blow back, an incorporated
accumulator tank with a volume of two lit-
ers is available as option. To drive this tank
an optional air actuated or solenoid valve is
offered.
The necessary dilution gas pressure can be
adjusted by the precision pressure controller
with pressure gauge.
A vacuum pressure gauge indicates the func-
tion of the dilution system.
The pressure controller and pressure gauges,
necessary for the dilution function, have to
be ordered separately. The external control
unit -S is equipped with an additional shut-
off ball valve and a flowmeter to adjust the
test gas quantity. The set -S1 includes an
additional pressure controller for the option
bypass injector -B or -BR.
The dilution probe realises dilution rates in
a range of 10:1 to 500:1. A high dilution rate
causes a low sample flow from the process.
With underpressure conditions the response
time can be minimised using the optional
heated bypass injector -B which is integrated
directly upstream the dilution unit. It is avail-
able with recirculation into the process -BR
as well.
The construction of the probe guarantees
an operation which is independent from the
process temperature and is easy to maintain
as well.
