1.1.2.2 Electrical and pneumatic connections
1.1.2.2.1 Fixed tight box version (Figure 1–3)
The gas inlets/outlets
–
The "SAMPLE OUTLET" for connection to an open air venting system, if necessary, is made up
with a 4/6 mm PVDF connection (1).
–
The "SAMPLE" inlet is made up with a 2/4 mm Teflon connection or with a 4/6 mm PVDF connec-
tion (2).
–
The "ZERO AIR" inlet for connection, at less than 10
3
hPa pressure, to a nitrogen gas cylinder or to
a dry and oil-free air instrument, is made up with a 4/6 mm PVDF connection (3). It can be also
connected to the automatic calibration module (TIG).
–
The "SPAN" inlet, for connection to a gas cylinder or to a manual or automatic calibration module
(TIG), is made up with a 4/6 mm PVDF connection (4).
–
The outlet (5) of the oxygen cell (optional) is made up with 4/6 mm PVDF connections.

The gas inlets/outlets
–
The gas connection between the MIR 9000 tigh box and the sample is made through the heated
line (2). There is only one gaseous inlet for the "SAMPLE", "ZERO AIR" or "SPAN". Gases connec-
tions and solenoid valves are installed upper in the tight dilution box. The configuration allows a
span check of the complete measuring system.
– The "SAMPLE" inlet is fitted with an antidust filter (7 µm) integrated under the measurement cham-
ber upper heating plate.
–
The "SAMPLE OUTLET" for connection to an open air venting system is made up with a 4/6 mm
PVDF connection (1).
–
The air inlet for the ejector is made up with a 4/6 mm PVDF(3).
