6 INTRODUCTION
Dilution probes are used wherever dilution of the sample gas is necessary for the measurement of one
or several sample gas components. Examples are the measurement of toxic gas components, moisture measurements or adjustment of the sample gas concentration to the analyser measuring range.
M&C dilution probes type SP2000H/DIL... are based on the modular probe type SP2000-H. The diverse variants, filter techniques and materials available ensure optimal adjustment to the particular
process conditions.
7 DESCRIPTION
The probe types SP2000H/DIL/2x, .../DIL/VA/B, .../DIL/BR are shown below.

To prevent cooling below dew point at the dilution point, the dilution unit with critical orifice is installed temperature-stable in the heated part of the gas sample probe directly in the clean gas outlet.
A gas pre-heater heats the dilution gas to probe temperature. With the option ..B/..BR wit bypass injector the bypass gas is pre-heated as well (double pre-heater). The probe is available with heating to
maximum 180°C or 320°C.
Test gas can be supplied to the probe for analyser calibration via the integrated test gas feed connection .

The probe can also be provided with an optional hand-operated, heated shut-off ball valve in the inlet VA (see Fig. 2) for the purpose of sealing off the filter space from the sampling process during filter
replacement. Another option is the second sample outlet for undiluted gas (..2x, see Fig.1)
A precision pressure regulator with pressure gauge serves for adjustment of the necessary dilution
gas supply pressure. The function of the dilution injector is monitored via a vacuum pressure gauge.
The pressure regulator and pressure gauge necessary for the dilution function must be ordered separately. Set -A is mounted directly on the probe. Control panel -S is designed for external installation
and is additionally provided with a shut-off valve and flow meter for test gas volume adjustment. The
options -A1 and -S1 include an additional pressure regulator for the bypass injector –B or bypass
injector with process return –BR (see Fig. 1).
Figure 4 Installation set and control panel
The dilution probe can be used for standard dilution factors from 10:1 to 500:1 (Injector I). Higher dilution rates in a ratio of 50:1 to 2000:1 are possible (Injector II).
Where a correspondingly small sample gas volume is taken from the process with large dilution factors, an optional heated bypass injector that is integrated directly upstream of the dilution part is available for reducing the response time in atmospheric respectively small vacuum operation. The bypass
option is available without gas return –B or with gas return to the process –BR . In vacuum operation, a bypass needle valve –BV serves for bypass volume adjustment (see Fig. 3).
The dilution unit is designed for problem-free operation independent of the process temperature and
process pressure (see technical data) as well as for easy maintenance.
