1-4 Description and Specifications Rosemount Analytical Inc. A Division of Emerson Process Management
Oxymitter 4000
3. Membrane keypad and HART commu-
nication are standard. To use the
HART capability, you must have either:
(a) HART Model 275 Communicator.
(b) Asset Management Solutions
(AMS) software for the PC.
4. Field replaceable cell, heater, thermo-
couple, and diffusion element.
5. The Oxymitter 4000 is constructed of
rugged 316 L stainless steel for all
wetted parts.
6. Integral electronics eliminates tradi-
tional wiring between probe and elec-
tronics.
7. The integral electronics are adaptable
for line voltages from 90-250 VAC;
therefore, no configuration is
necessary.
8. The Oxymitter 4000 membrane keypad
is available in five languages:
English
French
German
Italian
Spanish
9. An operator can calibrate and diagnos-
tically troubleshoot the Oxymitter 4000
in one of three ways:
(a) Membrane Keypad. The mem-
brane keypad, housed within the
right side of the electronics hous-
ing, provides fault indication by
way of flashing LEDs. Calibration
can be performed from the mem-
brane keypad.
(b) Optional HART Interface. The
Oxymitter 4000’s 4-20 mA output
line transmits an analog signal
proportional to the oxygen level.
The HART output is superimposed
on the 4-20 mA output line. This
information can be accessed
through the following:
1 Rosemount Model 275 Hand-
held Communicator - The
handheld communicator re-
quires Device Description
(DD) software specific to the
Oxymitter 4000. The DD soft-
ware will be supplied with
many Model 275 units but can
also be programmed into ex-
isting units at most Fisher-
Rosemount service offices.
See Section 5, HART/ AMS,
for additional information.
2 Personal Computer (PC) -
The use of a personal com-
puter requires AMS software
available from Fisher-
Rosemount.
3 Selected Distributed Control
Systems - The use of distrib-
uted control systems re-
quires input/output (I/O)
hardware and AMS soft-
ware which permit HART
communications.
(c) Optional IMPS 4000. The Pro-
grammable Logic Controller (PLC)
in the IMPS 4000 provides fault in-
dications using flashing LEDs and
LCD display messages. Refer to
the IMPS 4000 Intelligent Multi-
probe Test Gas Sequencer In-
struction Bulletin for more
information.
10. The optional Rosemount 751 remote-
mounted LCD display panel is loop-
driven by the 4-20 mA output signal
representing the O
2
percentage.
