Sample dilution system version DIL-U consisting of dilution probe SP2000H/DIL-U/P Special Features

Embracing Challenge
Sample dilution system version DIL-U
consisting of dilution probe SP2000H/DIL-U/P
and dilution pump unit DIL-U/A (N)
DIL-U/A(N)
Special Features
ƒƒ Lowest dilution ratio 1:1
ƒƒ Ambient air as dilution gas possible
ƒƒ Low dilution gas consumption
Application
The electrically heated M&C dilution system
DIL-U is applicable for such processes, where
the measuring procedure or the handling of
the process gas requires the dilution of the
sample respectively the component to be
measured in a range of 100:1 up to 1:1.
ƒƒ No influence of barometric pressure1
Typical applications:
ƒƒ Compact design
•
toxic gases above TLV value
ƒƒ Gas sample probe SP2000H/...
•
explosive gas mixture above LEL
ƒƒ Incorporated pre heater for dilution gas
•
adapting the concentration of the sample components to the measuring range
of the analyser
ƒƒ Test gas connection at the probe inlet
ƒƒ Completely heated up to 180°C
•
measuring possibility at low sample flow
rates from 1Nl/hr
varying process pressure must be taken into
consideration
•
moisture measurement in flue gas with
IR-analyser

The M&C dilution probe (part of this system)
is based on the well tested modular designed
M&C gas sample probe SP2000H. This enables
the user to adapt the probe to nearly every
application, using for example special filter
techniques or special materials.
For test procedure with zero and span gas a
3 way ball valve and a flowmeter is installed.
Version DIL-U/A is suitable for ambient air as
a dilution gas and version DIL-U/N for bottle
gas. Bottle gas requires a pressure regulator,
a pressure gauge and a flowmeter which can
be installed optional in the pump unit.
If the dew point of the diluted sample is
higher then ambient temperature an optional integrated M&C cooler, ECP1000G/SR25,
reduces it to +5 °C.
High dilution ratios cause a very low sample flow. Therefore it is necessary to use an
additional sample bypass 2 to reduce the
response time. This will be done with the
option DIL-U/B with an additional pump and
flowmeter and the cooler as an option.
The heated M&C sample line(s) 3/4-N/M/H
between the probe and the pump unit can
be controlled via an temperature controller
703, built into the pump unit.
The design of the dilution system DIL-U guarantees easy maintenance.
Description
The M&C dilution system DIL-U consists of the
dilution probe SP2000H/DIL-U/P and the dilution pump unit DIL-U (A/N).
The dilution unit, including the critical orifices, is integrated in the sample probe outlet,
heated up with the probe to a stable temperature. The incorporated pre heater heats
up the dilution gas to the probe temperature.
Both steps avoid that the temperature of
sample gas decreases under the dew point.
The test gases for the system calibration enter
the sample probe via an integrated valve.
A vacuum pump integrated in the pump unit
DIL-U sucks the required vacuum, which is
necessary for the function of the critical orifices. A pressure gauge indicates the function of
the dilution system. The flowmeters indicate
the analyser and bypass flow 1. A flow alarm
is available as well.
