6 INTRODUCTION
The non-heated or electrically heated M&C dilution unit DIL-1 /(H) is used in the analysis technique
whereever the measuring method or the handling of the process gas requires a dilution of the sample
gas or the components to be measured. Examples are the measurement of extremely toxic gases, the
determination of the gas moisture or emission measurement.
The M&C dilution unit is based on the functional dilution technique which is proved since years in the
M&C gas sample probe SP2000-H/DIL.
For further information or personal advice, we have pleasure to be at your disposal. Further you may

The M&C dilution units DIL-... are mounted on a plate for wall mounting. The operating temperature of
the non heated version DIL-1 is the ambient temperature. Version DIL-1/H is heated up to 180 °C and
is equipped with a heat insulated cover (Version for 320 °C on request).
The temperature is regulated by an integrated capillary thermostat, adjustable from 0-180 °C, including an excess temperature limiter and a low temperature alarm. (Optional: Temperature sensor PT100
or thermocouple “”K” for external temperature controller on request)
The connection of the heated lines is made without cold bridges into the heated part. Before the dilution gas enters the dilution unit, it is heated up to the operating temperature via a gas pre-heater. In
order to protect the dilution part against contaminations, internal protective filters are installed for the
sample gas and the dilution gas stream.
For calibration of the analyser, test gas can be feeded via the integrated test gas connection. A precision pressure controller with manometer is used for adjustment of the necessary dilution gas admission pressure. Via a vacuum pressure gauge, the function of the dilution injector is controlled. Both,
pressure controller and pressure gauge have to be ordered separately. Two versions are available:
Set -A (-A1) for direct mounting on the mounting plate and control panel type -S (-S1) for external 19"
rack mounting. A shut-off valve and a flowmeter for adjustment of the calibration gas are included in
the version –S (-S1).
The dilution unit can realize dilution ratios of 10:1 to 500:1. In case of high dilution ratios, a respective
small quantity of gas is sampled from the process. Optionally, a bypass injector –B (Option I) is available in order to shorten the response time in case of operation with atmospheric pressure. The bypass
injector is integrated right in front of the dilution unit.
The pressure regulator versions –A / -S include a pressure regulator with manometer for the dilution
gas as well as a manometer for control of the depression on the critical orifice. In case of option I, an
additional pressure controller with manometer is included in both mounting versions -A1 / -S1.
The construction of the dilution unit guarantees easy operation and maintenance being independent
from process temperature.
