7.1 VARIATIONS
The two basic versions DIL-1 and DIL-1/H can be extended by several options.
Option I
Includes a bypass for dilution gas with bypass injector for a fast suction of sample gas in order to
shorten for example the response time in case of high dilution ratios.
Option II
Includes an additional sample gas outlet „non-diluted“.
Option
–A
Includes a pressure regulator with manometer and a manometer for control of the low pressure on the
critical orifice. These are mounted directly onto the dilution unit. (see figure 6).
Option
–A1
Includes in addition to option -A a pressure regulator with manometer for operating the bypass of op-
tion I. This option is also mounted directly onto the dilution unit (see figure 6).
Option
–S
Includes the necessary pressure regulator with manometer, shut-off valves and flowmeter, incorpo-
rated externally in a 19“ control panel (see figure 5). The connection of the sampling or the supply
lines to the downstream analysis system have to be executed by the client. Connections which are
mar
ked accordingly are available on the back side of the 19“ unit.
Option
–S1
Includes in addition to option -S the pressure regulator with manometer for operating the bypass of op-
tion I, mounted externally into the 19“ control panel (see figure 5). The connection of the sampling or
supply lines to the downstream analyse system has be made by the client. Connections which are
marked accordingly are available on the back side of the 19” unit.
The following illustrations show the gas flow of the dilution units DIL-1 and DIL-1/H with all possible
options.
