5 Setup and function
5.1 Functional description
The cabinet sample module series SAM-1000_DP is used to connect different sample points to analysers.
Because of its modular design, it can be used for various applications in the chemical and petrochemical
industries for gaseous high-purity gases.
Special features:
The SAM-3000 especially distinguishes itself through the following features:
•
Compact construction
•
Minor dead volume
•
Modular configuration
•
High leak thightness
•
Multi-purpose applications possible
•
PROFIBUS connectivity possible (optional)
Depending on the expansion stage of SAM-3000 can be switched up to 4 sample gases and 2 calibration
gases to an analyzer. For monitoring the gas ways at a glance LED’s shows the selected way. The LED’s
can be optionally arranged as Pushbuttons. Filter frits at the inlet of the switching module protects the
following analysers. So that impurities are filtered out of the sample gases and avoids pollutions and
damages at the analyzer. Filter frits are available in 20 μm and 50 μm fineness of filtration. With the
solenoid valve manifold concerning purging or no purging the dead volumes are minimized. For high pu-
rity applications the solenoid valves on the manifold are optimally arranged. By activation of a solenoid
valve a potential free contact can be used to send a feedback signal to the DCS. Up to 4 flow indicators
can be used to monitor the flow rate of sample gases. The SAM-3000 optional includes an integrated
pressure transmitter. The estimation of additional attended connectors and tubing connections can be
much reduced and supports a fast installation. A high variety of connectors can be chosen for different
tubing diameters. Depending on application different materials for the tubing inside of SAM-3000 can
be selected. Free configurable bridge circuits on control PCB compliance individual requirements. So for
e.g. the LED’s displays the individual task of function. Optionally the SAM-3000 can be connected to a
Profibus.
