cables are included in the boxes of additional peripheral devices supplied with the analyzer.
These are adapted to the interfaces when the analyzers are put into operation in our company.
The serial interface of the balance is programmed in order to match the required configuration
for weight transfer to the PC.
The computer is already provided with an operating system and software for controlling the
analyzer.
NOTICE
For information about using the PC for operating the analyzer, refer to the UNI-software help
manual.
4.5 Gas connections
Four tube connections are necessary for the operation of the analyzer. The required tubes are
included in the delivery. See diagram above.
– One tube for Oxygen supply with 5 meters length and fitting.
– One tube for the compressed air with 5 meters length and fitting.
– One black tube of 0.8 meters length for the resistance furnace inlet.
– One white tube of 0.8 meters length for the resistance furnace outlet.
The 5m long tubes are delivered with fittings for pressure regulators with R¼" inner thread as
well as the copper gaskets.
The tube (3) connects the analyzer with an oxygen bottle via a pressure regulator. This
connection must be very secure, since the operating pressure in the tube is 2 to 4 bar (30 to 60
psi). Gas connection (1) is for the compressed air supply to the pneumatic furnace piston and to
the internal cooling of the induction coil. The pressure is 4 to 6 bar (60 t0 90 psi).
Gas connection (2) is for the gas outlet to lead to a vent or hood. It is mostly not used, since
only low quantities of CO2 and even lower quantities of SO2 result from the sample combustion.
