15.1 Connecting The Heated Sample Line; Connection Of Supply Gas Lines (Dilution Gas Or Blow Back) - M&C SP Series Instruction Manual

15.1 Connecting the heated sample line

To connect the sample line, a threaded tube connector with Ø 8 x 1 mm is available – other
•
diameters available on request.
Insert the tube connection piece into the bolted pipe joint and connect them.
•
If using a PTFE tube as sample line, a metal tubing sleeve for pneumatic fittings needs to be
•
inserted at the end of the tube to prevent it of being pressed together.
• The temperature-resistant, stainless steel connector from M&C has a double-blade ring system
to ensure reliable sealing. First finger-tight the nut of this connector, then use a flat spanner to
turn the nut exactly 1¼-turns. The nut is now correctly mounted.
Note

15.2 Connection of supply gas lines (dilution gas or blow back)

Tube connectors in size DN 4/6 mm are available to connect the supply lines to the sample dilution
probe.
SP190-H/DIL-EX2 T* with weather protection cover: The tube connectors are located under the
protection cover. To connect the supply lines, the protection cover needs to be removed.
When using a 19"-control panel, the corresponding connectors for the supply gases are marked and
located at the back of the unit.
The result of the measurements can be significantly influenced by pressure increase caused by using
long sample gas lines. To avoid increasing pressure, we recommend the following inside diameters
and length for the sample gas lines of the injectors:
Injector
Injector I
Injector II
* Standard, other versions on request.Please specify dilution ratio with your order.
