3.3 Identifying the Probe
Each probe is identified by 2 probe-specific labels attached to
the probe head (separate transmitter-specific labels are also
attached to each system transmitter).
The probe labels comprise:
a
Data Label – used to identify the probe code
A
, probe
serial number
B
, probe power rating
C
and approval
symbols
D
(if applicable).
2
Commissioning Label – contains the cell number
A
, date
B
, cell zero
C
and the calibration factor value
D
required to calibrate the probe for the zirconia cell fitted –
see IM/AZ20E-EN for commissioning procedures.
The Commissioning Label also indicates if automatic
calibration and / or restrictors have been added. If either
item has been added, the information on this label
overrides some of the product code on the Data Label
1
.
Warning.

Before installing the probe, check the probe data and
the alteration labels on the head of the probe – see
Section 3.3.

Select a location away from strong electrical and
magnetic fields. If this is not possible, particularly in
applications where mobile communications
equipment is expected to be used, screened cables
within flexible, earthed metal conduit must be used.

Before installing the probe, read the Safety notes
in Section 1.

Ensure suitable lifting equipment and qualified
personnel are available to suit the probe length being
installed – see page 16 for probe weights.
Caution. Visually inspect equipment for damage before
installing. Do not install damaged or faulty equipment.
Warning.

Handle the probe with care and do not subject it to
hammer blows or other sharp shocks. The probe
inners have fragile ceramic components that can be
damaged.

It is recommended to retain the protective probe
packing materials to allow for re-shipping in the
unlikely event of a return.
Caution. Details on the probe labels are unique to the cell /
probe combination they are attached to and cannot be
used to identify any other probe or system.
