On devices for legal metrology, the hardware write protection
must be activated after commissioning in many cases.
This prevents a change in the parameterization of the devices.
Hardware settings
on page 71
To prevent deactivation of the hardware write protection or
other manipulations during operation, the transmitter housing
and the sensor housing connection box (with remote mount
design) must be sealed.
For this purpose, a seal kit is available at ABB.
For the assembly of the seal, please observe the separate
‘IN/FCX100/FCX400/MID/OIML-XA’ instructions.

Measuring medium temperature T
medium
• FCx430:
−
50 to 160 °C (

58 to 320 °F)
• FCx450:
−
50 to 205 °C (
−
58 to 401 °F)
In devices with order code ‘Extended tower length – TE3’, the
measuring medium temperature must be limited to a maximum
of 140 °C (284 °F) from an ambient temperature of
≥
65 °C
(149 °F).

Note
When operating below -20 °C (-4 °F), the LCD display can no
longer be read and the electronics should be operated with as
few vibrations as possible.
Full functionality is assured at temperatures above -20 °C (-4 °F).
Storage temperature of the devices in the ‘Standard’ version
without cable glands is also
−
40 to 70 °C (
−
40 to 158°F).
Pressure ratings
The maximum permissible operating pressure is determined by
the respective process connection, the temperature of the
medium to be measured, the screws, and the gasket material.
For an overview of available pressure ratings, see Device
overview in the data sheet.
