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)
• Lowest dilution ratio 1:1
Application
• Ambient air as dilution gas
possible
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.
• Low dilution gas consumption
• No influence of barometric
pressure1
• Compact design
• Gas sample probe SP2000H/...
• Incorporated pre heater for
dilution gas
• Test gas connection at the
probe inlet
• Completely heated up to 180°C
1
varying process pressure must be taken into
consideration
Typical applications:
•
•
•
•
•
toxic gases above TLV value
explosive gas mixture above LEL
adapting the concentration of the sample components to the measuring
range of the analyser
measuring possibility at low sample flow rates from 1Nl/hr
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.
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 preheater 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. 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. Therefor 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.
