18 EL3060 CONTINUOUS GAS ANALYZERS | OI/EL3060-EN REV. A
Material required for the installation (not supplied)
Gas connections
• Threaded connections with ⅛ NPT threads
• PTFE sealing tape
Flow meter / Flow monitor
• Flow meter or flow monitor with a needle valve for adjustment and mon-
itoring of the sample gas flow rate and purge gas flow rate if required
• Recommendation: Flow meter 7 to 70 l/h, Order no. 23151-5-8018474
Flow limiting device
• The flow of sample gas entering the gas analyzer must be limited by
means of an external flow limiting device.
• The flow limiting device must comply with the requirements of
EN 60079-1:2014, Annex G, Section 3.3.
• The maximum permissible flow rate data of the individual analyzers and
device variants must be observed.
Shut-off valve
• Install a shut-off valve in the sample gas supply line (definitely recom-
mended with pressurized sample gas).
Purging of the gas line system
• Provide a means for purging the gas line system by feeding in nitrogen
from the gas sampling point.
Installation material
• EL3060-CU control unit: 4 bolts M8 or M10
• EL3060-Uras26 analyzer unit: 4 bolts M8
Electrical cables
• Design of the electrical connections: Terminal strips with screw connec-
tion
• Conductor size:
• single-core: 0.5 to 4 mm
2
• multi-core: 1.5 to 4 mm
2
• stranded: 0.5 to 2.5 mm
2
(only with wire end ferrule)
• Select conductor material which is appropriate for the length of the lines
and the predictable current load.
• Provide disconnecting devices in the power supply cable and the signal
lines, in order to be able to disconnect all poles of the gas analyzer from
all power sources if required.
