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 Lowest dilution ratio 1:1 Ambient air as dilution gas possible 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. No influence of barometric pressure1 Typical applications: Compact design • toxic gases above TLV value Gas sample probe SP2000H/... • explosive gas mixture above LEL Incorporated pre heater for dilution gas • adapting the concentration of the sample components to the measuring range of the analyser Test gas connection at the probe inlet 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 1 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.
