3.5
Analyzing Board
The analyzing board is designed for mounting with the G
36a
Oxygen Analyzer or the G
36p
Oxygen Analyzer for panel mounting. For the G3620p, the analyzing board is connected
to the panel mounted analyzer by a standard 3 m long signal cable. This signal cable can
be delivered up to 6m as optional.
The analyzing board has two angle iron mounting brackets. The brackets are made of
ordinary mild steel and can be welded or bolted directly to a chosen location structure as
required.
The two mounting brackets are mounted horizontally and parallel with a distance of 577
mm.
When the analyzing board and the ejector probe are installed in appropriate locations, the
instrument air and power can be connected as described below.
3.5.1
Air supply connection
For ejector air, back-flushing, and calibration, instrument air is connected directly to the
air supply filter reduction station. The reduction station consists of a filter and a drain.
The air supply connection to the reduction station is a 1/8” BSP female connection. The
maximum pressure for the air supply inlet is 10 bar.
3.5.2
Test gas connection
For system verification, test gas is connected to the inlet valve. The connection is a quick
coupling for OD 6/4 mm hose. The maximum pressure for the test gas inlet is 1 bar.
3.5.3
Analyzer and Electrical Connection
For the SGOA system installation, the instructions for the electrical connections are
described in the oxygen analyzer manual chapter 3.
