3.3 Accessories
3.3.1 Sealing cap (0699 6446/41)
Only for 0699 6446 Standard version.
The sealing cap with internal thread is used for operating the pipeline without
the mass flow sensor.
3.3.2 Connecting cable with electrical isola-
tor (0699 6446/42)
Uniform for all versions.
A connecting cable with an electrical isolator integrated into the connector is
available as an accessory. The cable is 5 m long and is used for the galvanic
isolation of the signal output to the electronics to which it is attached. The
cable is delivered with an appropriate connector for the mass flow sensor on
one side and with open cable ends on the other side.
3.3.3 Replacement for electronic sensor as-
sembly (0699 6446/31 or 0699 6447/31)
The electronic sensor assembly is adjusted to the data of the measurement
block (diameter/medium). For this reason, only an identically adjusted model
can be used when replacing the component. When ordering spares, the data
of the measurement block must be stated.
The replacement for the electronic sensor assembly is used as a backup in
the event of damage to or loss of the original mass flow sensor or the entire
assembly.
When ordering, the nominal width must be given for the calibration of the
electronic sensor assembly.
