Pneumatic Connection
Looking at the FTC200-OEM on the side of gas tubes with the PCB up, the
gas inlet is on the right-hand side. Gas inlet and outlet tubes – as well as
the body - are stainless steel (LF316ti). The outer diameters of the tubes
are 6mm. The gas must not contain dust, condensate and potentially
condensing matter. The inner gas duct is stabilized onto 63°C (hotter
versions on demand). Depending on mounting, thermal insulation, sample
flow and temperature and ambient conditions, the temperature of the inlet
tube maybe significant lower. This fact might give reason to condensation
at dew points well below 50°C. With proper heated lines and insulated
connectors, a dew point up to 50°C is permissible.
!!! Important Notice !!!
Condensate will destroy the sensing element immediately (condensate and
dust tolerant version on request).
Optimal flow is in between 60l/h and 80l/h. If the flow is kept stable during
measurement as well as during calibration a range from 10l/h to 100l/h is
possible.

Mounting
The bottom view of the FTC200-OEM shows four M3 thread holes which
may be used for the fixation of the detector. Use insulating spacers (min.
4mm) and stainless-steel screws in order to minimize heat flow from the
63°C hot detector body. For bulkhead mounting two spacer and two M8
nuts are available on request.
