SECTION 1.0
GENERAL DESCRIPTION AND SPECIFICATIONS
1.1 FEATURES AND APPLICATIONS
The Rosemount Analytical®Model 430 Dissolved
Oxygen Sensor, used with the Model 1181 Dissolved
Oxygen Transmitter, measures oxygen levels in a variety of applications. The most widely used application is
the secondary phase of the waste treatment process
where a critical dissolved oxygen level must be maintained for the digestive process to occur. Other applications include water quality monitoring in natural bodies of water such as rivers and streams, or any location
where adequate oxygen content is important to sustain
aquatic life.
The Model 430 Dissolved Oxygen Sensor is constructed of PVC with an oxygen permeable Teflon1membrane .
1.2 OPERATION
As oxygen passes through the Teflon membrane an
oxygen dependent electrochemical reaction takes
place between the gold cathode and silver anode in the
presence of the electrolyte. The resultant current flow
between these elements is proportional to the quantity
of oxygen which has entered the sensor.
Temperature and pressure compensation are both
standard features on the Model 430. Temperature compensation is necessary for two reasons: First, the solubility of oxygen in water decreases with an increase in
temperature; secondly, the permeability of the Teflon
membrane and the oxygen diffusion rate increase as
the temperature increases. For these reasons, it is
important for a dissolved oxygen measurement to be
accompanied by an accurate temperature measurement. Temperature compensation is accomplished by
means of a thermistor located in the sensor housing,
and its associated circuitry in the analyzer.
Pressure compensation is a mechanical rather than
electronic correction. It is important for the tension on
the Teflon membrane to remain constant at all times,
even with sample pressure changes. Fluctuations in
membrane tension affect its diffusion characteristics.
By means of a pressure compensator the pressure on
the sample side of the compensator membrane is
transmitted to the electrolyte reservoir so the pressure
on both sides of the membrane remains equal. In this
manner, sample pressure changes do not affect the diffusion rate of oxygen through the membrane.
The Teflon membrane is held in place by a retainer. A
water-tight seal is made with an O-ring between the
membrane and sensor reservoir. Membrane replacement is rarely required, but in those situations when it
is necessary, the procedure can be performed quickly
and easily.
Since oxygen diffuses through the Teflon membrane at
a faster rate than through the sample, it is necessary to
continuously maintain a fresh sample in front of the
membrane. A stream velocity of approximately 1.5 feet
per second (0.5 m/s) is required to ensure that a fresh
sample is in contact with the membrane at all times.

DESCRIPTION AND SPECIFICATIONS
1.3 AVAILABLE MODELS
The Model 430-01 and -02 Sensor is a flow through
assembly. The sensor is supplied in a 1-1/2 inch PVC
tee for installation into a process line.
The Model 430-03 Submersible Sensor is for use in
those applications where the required flow velocity can
be maintained without the use of an agitator. When the
measurement is being made in a stagnant pond or
other media where the minimum flow rate of 1.5 FPS
cannot be obtained, the Model 430-04 must be selected. This model is designed for submersible use and is
provided with its own agitator to ensure adequate flow
velocity at the membrane.
The Models 430-03 and 04 may be provided with an
optional mounting bracket assembly. This bracket is
constructed of light weight aluminum and can be
adjusted to satisfy virtually any aeration basin mounting requirement. Once installed, the probe can be
removed without the use of tools. A single locking pin
holds the assembly rigidly in place but allows it to be
easily removed for inspection or cleaning.

MAINTENANCE
SECTION 3.0
MAINTENANCE
3.1 GENERAL. Sensor maintenance consists of keep-
ing the sensor clean, recharging the sensor and
replacing the membrane. The sensor should be
cleaned with clean water and a soft cloth. Make sure
the membrane area is kept clean and free of any
accumulation of dirt, algae, fungus, hair, etc.
3.2 RECHARGING THE SENSOR. A recharge kit
(Rosemount analytical P/N 2002473) is required to
service the sensor.
Recharge the sensor as follows (see Figure 5-2):
1. Remove the sensor from its mounting.
2. Loosen the vent screw approximately 1-1/2 turns.
DO NOT REMOVE IT
3. Unscrew and remove the reservoir retainer from
the base. Use a strap wrench if the retainer is to
tight to remove by hand.
4. Pull the reservoir housing assembly from the base
WITHOUT rotating it. Hold sensor in a base-up
position to keep electrolyte from spilling out. If the
reservoir housing assembly is locked onto the
base, use a screwdriver at the parting lines to dislodge the base from the reservoir housing assembly. Do not damage the mating surfaces with the
screwdriver while separating the base from the
reservoir housing assembly.
CAUTION
The electrolyte (KCI) is a corrosive liquid
which could damage some materials and
may irritate the skin or eyes. If the electrolyte
comes in contact with the skin or eyes, wash
immediately with clean water.
5. Discard the O-ring, electrolyte, and reservoir
housing assembly.
6. Prepare the electrolyte solution as follows:
a. Pour electrolyte crystals into a beaker containing
100 milliliters of distilled or demineralizer water.
Stir until crystals are dissolved.
b. If it is desired to forego the stabilization period of
two hours, a dilution of the electrolyte may be
done by adding NaOH or KOH to adjust the pH of
the solution to 12 or greater.
c. The unused electrolyte solution can be saved for
future use. The pH should be rechecked prior to
use if the solution has been stored.
7. Fill the new reservoir housing assembly with electrolyte to the hole in the inner wall of the reservoir
(approximately 3/4 full). Tap the reservoir lightly to
remove any air bubbles.
8. Rinse all parts of the base in distilled or deionized
water. To remove silver chloride from the silver
anode, use a fine grit sandpaper or a pencil eraser and rub lightly until the coating is removed.
Rinse the silver anode in distilled water until all
traces of grit are removed.
9. Lightly lubricate the O-rings with O-ring lube and
install the O-ring in the groove of the base.
10. Hold the reservoir housing assembly in an upright
position and carefully slide the base into the reservoir housing assembly, making sure the tip of the
post enters the membrane retainer. Some electrolyte should seep out through the vent screw
while the reservoir housing assembly is being
pushed onto the base. Do not grip the pressure
compensator while pushing the reservoir housing
assembly onto the base.
CAUTION
In the following step, do not push the reservoir housing assembly onto the base too fast.
The orifices in the base vent screw are very
small and a quick surge of pressure could
damage the membrane. A stream of electrolyte solution could be forced through the
vent screw while the reservoir housing
assembly is being installed.
11. Push the reservoir housing assembly onto the
base until the threads of the base and the reservoir retainer can be engaged. After the threads are
engaged, turn the reservoir retainer until it is finger-tight. Caution, over finger-tight may damage
membrane or base post.
NOTE
Do not touch or apply pressure to the membrane.
12. Tighten the vent screw. Rinse the sensor with
clean water and dry with a lint-free cloth or towel.
13. The sensor is now ready for use.

4.1 GENERAL. This section contains troubleshooting
data for the Model 430 Sensor Assembly.
4.2 TROUBLESHOOTING THE MODEL 430
DISSOLVED OXYGEN SENSOR. The majority of
problems encountered in DO systems are because the
sensor is either improperly maintained or has an internal leakage causing improper temperature compensator resistance and high impedance current paths
between elements of the sensor.
Disassemble the sensor completely by unscrewing the
reservoir retainer and pulling the reservoir housing
assembly straight out (refer to Figure 5-2). The membrane may have dried onto the gold cathode. Soak this
loose with water as scraping will damage the gold tip.
Clean all the parts with clean water and dry them.
Check for visible damage (i.e., cracks, deep cuts, broken silver wires). Perform the following checks with an
ohmmeter. Check T.C. resistance between the green
and white wires. It should be 100K ohms at 25°C or per
the Temperature/Resistance Chart. Check continuity
between the red wire and the silver anode, and
between the black wire and the gold cathode (be careful not to scratch the gold). Perform a high meg check
between the following (100 meg ohms minimum):
Shield to Black or Red or Green. If everything checks
O.K., the sensor should function after a proper
recharge. If the silver anode appears oxidized, it may
be cleaned with wet or dry 400 sandpaper. Also brush
the gold tip two or three times with the 400 sandpaper
in one direction only. Follow the recharge directions in
Section 3.2.
4.3 BENCH TESTING. Soak the electrode for 24 hours
with polarizing voltage applied (instrument), then air
calibrate to check for a response.
CAUTION
Care should be taken not to damage the
membrane made of “Teflon”.
1. Low readings and inability to calibrate are
generally the result of a coated membrane
and usually can be restored to service by
cleaning the sensor. Clean a coated membrane by gently wiping the membrane with a
soft cloth or tissue.
1
Reg. U.S. Pat. Office for du Pont’s fluorocarbon resins.
2. Readings offscale and inability to calibrate
are usually caused by a damaged membrane. If this is the case, replace the membrane.
3. To check the membrane made of “Teflon”,
connect the negative (—) lead of an ohmmeter to the cathode (black) lead and
place water saturated with salt on the
membrane. Touch the positive (+) lead to
the water. The meter should read open
(100 megohms or more). If the meter indicates a short (less than 100 megohms),
replace the membrane (refer to Section
3.2).
4. To check the resistance of the temperature
compensator, connect an ohmmeter to the
green and white leads of the sensor. The
resistance should be as indicated at the
temperature listed below: If the resistance
as specified above cannot be achieved,
replace the sensor (Figure 5-2).
Temperature Resistance Chart
5. To check for shorted sensor leads, measure the resistance between one temperature compensator wire (green or white) and
the cathode (black) lead and anode (red)
lead. The meter should indicate an open
circuit (100 megohms or more). Repeat the
measurement using the other temperature
compensator wire. If the sensor shows a
short circuit, the sensor is defective and
should be replaced.
