In this typical graph, the plotted
points have been selected from the
titration data of an acid process
neutralized by sodium carbonate.
Up to 16 such data points can be
entered directly into the memory of
the 7084 Analyzer/Controller via
the front-panel keyboard. As the
measured pH varies, the 7084
tracks the linear segments
between points, characterizing the
pH-vs-reagent demand. (See
below)
Note that spacing between points
can be selected to maximize the
conformity to any titration-curve
shape; multiple inflection points are
easily accommodated.

Preamplifier/electrode system
The 7084 Analyzer/Controller is
designed for compatibility with
Honeywell’s preamplifier/electrode
mountings. The environmentally
sealed, high-impedance
preamplifier is located in (or
adjacent to) the electrode
mounting, with the measuring and
reference electrodes and automatic
temperature compensator.
Electrodes and compensator are
directly connected to the
preamplifier. A unique guarded
circuit protects the input and
provides a thousandfold decrease
in sensitivity to leakage currents.
The “guarded” preamplifier
conditions and amplifies the
electrode signal locally and
transmits the low-impedance signal
to the analyzer over ordinary
unshielded wire.
Signals can be transmitted over a
distance of 1830 m (6000 ft) or
more. The preamplifier/analyzer
system has high immunity to
ground-loop “noise” and spurious
RF signals. Grounded or
ungrounded solutions can be
measured and no solution ground
connection is required. The
preamplifier is lightning-protected,
which cannot prevent failure
caused by very near or direct
strikes, but does provide
substantial protection to the
preamplifier itself by dissipating
normally destructive surge currents
through the electrodes.
Electrolert test
The patented Electrolert feature
uses the microprocessor to monitor
the performance of the pH
measuring electrode for breakage,
or for a complete loss of sample to
the electrodes.
The Electrolert circuitry can also
actuate triac or relay contacts,
helping to ensure dependable pH
control in critical processes where
an electrode failure could result in
poor quality of the final product, an
out-of-control situation, the loss of
an entire production run, or
contamination of the product by
broken electrode glass.
Operation of the
Electrolert warning circuitry
requires the use of Honeywell
electrodes.
Self-diagnostics
The microprocessor continuously
checks the 7084
Analyzer/Controller for proper
operation. If a failure occurs in the
RAM or ROM, or with an incoming
4-20 mA signal, or if there is
excess electrical noise at the
electrodes or in the wiring, an
appropriate message (e.g., “FAIL
2”) will appear on the LCD.
Failure alarm
The failure alarm is an alarming
mode comprising (1) a flashing
display on the LCD of the specific
alarm message, (2) a low-power
output to an external horn, and (3)
actuation of a triac or reed-relay
output (optional). The alarm is
activated by electrode failure
(detected by Electrolert) or
analyzer failure (detected by selfdiagnostics); it can also be
programmed to alarm at the end of
the electrode service interval, or
when setpoints for the pH alarms
are exceeded.
not, however, compensate for
changes in solution pH with
temperature.
Solution-temperature
compensation in the 7084 allows
the user to compensate for this
variation in any process.
With this feature, measurement is
made at any temperature, but the
pH value displayed is referenced to
25°C. By using the “HOLD” mode,
the feature is disabled so that true
pH is displayed—and can be
calibrated with buffer solution at
any temperature.
This feature facilitates
measurement in applications where
long sample lines result in
significant temperature variation of
the sample (such as power-plant
steam condensate), or in
processes that require a specified
pH at 25°C when process control is
at an elevated temperature.
Preventive maintenance
As a reminder to clean,
standardize, or service the
electrodes at a predetermined
interval, the analyzer features a
service timer, which can be digitally

If electrodes are removed from the
process for calibration in buffer

prevents change of the alarm

standardization, the displayed pH
value is “frozen” at the time the
sample is taken for subsequent
correction; the pH output and

programmer or computer.
Input impedance: For all 4-20 mA inputs, 25 ohms.
*(1) Transmitters cannot be powered from the 7084 Analyzer/Controller; (2) Electrolert
and temperature-compensation functions require signals directly from a Honeywell
Preamplifier Electrode Mounting.
Outputs
Isolated voltage: 0-1 Vdc (5-megohm minimum load impedance) or 0-10 Vdc (2000ohm minimum), jumper-selected, proportional to selected pH (or ORP) range.
Isolated current: 4-20 or 0-20 mAdc (900-ohm maximum load) or 0-16 mAdc (1150ohm maximum), jumper-selected, proportional to selected pH (or ORP) range.
NOTE: Voltage and current outputs are isolated from inputs, but are not isolated from each
other. Only one output signal can be grounded.
Current output is available for either CAT control or pH signal, NOT both.
Failure Alarm
Diagnostic circuitry continuously monitors electrode condition and analyzer/controller
performance; a message flashes in the upper LCD when failure occurs (with
optional horn and/or triac or relay action).
An acknowledge (ACK/CLR) button on the keyboard silences the horn and reverses
triac or relay action, but the message remains (without flashing) until the condition
is corrected.
70-82-03-02
Page 7
Specifications
Horn Output
A 15-Vdc, 10-mA signal is available at the terminals (under failure conditions) to energize a
low-power sound. This output is triggered by the Failure alarm, independent of the triac or
relay operations.
Display and
Programming
Keyboard
Comprises a bank of 24 keys, compactly mounted on the front panel beneath the LCDs; 11
keys provide a number pad (“0” to “9,” and “+/-”), permitting digital inputs and
programming; 13 keys call up various displays, enter digital values, switch from automatic
to manual control, initiate standardizing, etc.
Electrolert Protection
Measuring glass electrode is continually monitored by the microprocessor. In all operating
modes except “STD” and “SLOPE,” display of “FAIL ELECTRODE” indicates a broken
electrode or loss of sample within 10 seconds—can actuate Failure alarm, with or without
initiating failsafe control and triac or relay operation.
While calibrating in “STD” mode, “ELECTRODE SERVICE” display indicates excessive
electrode drift and need for reference-electrode replacement. While calibrating in “SLOPE”
mode, “ELECTRODE SERVICE” indicates measuring-electrode deterioration and need for
replacement.
