qualified on site safety personnel.

To secure and maintain an intrinsically safe installation, the certified safety barrier, transmitter, and
sensor combination must be used. The installation system must comply with the governing approval
agency (FM, CSA or BASEEFA/CENELEC) hazardous area classification requirements. Consult your
transmitter instruction manual for more details.

Proper installation, operation and servicing of this sensor in a Hazardous Area Installation is entirely
the responsibility of the user.

CAUTION

Sensor/Process Application Compatibility

The wetted sensor materials may not be compatible with process composition and operating
conditions. Application compatibility is entirely the responsibility of the user.

CAUTION

Special Conditions for Safe Use

1. All pH/ORP sensors have a plastic enclosure which must only be cleaned with a damp cloth to avoid

the danger due to a build up of an electrostatic charge.

2. All pH/ORP sensor models are intended to be in contact with the process fluid and may not meet the

500V r.m.s. a.c. test to earth.

This must be taken into consideration at installation.

Section 2: Installation

2.1 Unpacking and Inspection

Inspect the outside of the carton for any damage. If damage is detected, contact the carrier
immediately. Inspect the hardware. Make sure all the items in the packing list are present and in
good condition. Notify the factory if any part is missing. If the sensor appears to be in satisfac­tory condition, proceed to Section 2.2, Mounting.

NOTE: Save the original packing cartons and materials as most carriers require proof of damage
due to mishandling, etc. Also, if it is necessary to return the sensor to the factory, you must
pack the sensor in the same manner as it was received. Refer to Section 6.0 for return instruc­tions. If the sensor is to be stored, the vinyl boot should be filled with pH buffer solution and
replaced on sensor tip until ready to use.

CAUTION

Buffer solution, in the vinyl boot, may cause skin or eye irritation.

WARNING

Glass electrode must be wetted at all times (in storage and in line) to maximize sensor life.

2.2 Mounting

The sensor has been designed to be located in industrial process environments. Temperature
and pressure limitations must not be exceeded at any time. A caution label regarding this
matter is attached to the sensor. Please do not remove the label. See Figure 2-1.

CAUTION

Internal electrolyte fill solution may cause skin or eye irritation.

Mounting Guidelines:

1. Shake the sensor in a downward motion to remove any air bubbles that may be present
inside the tip of the pH glass.

2. Do not install the sensor on the horizontal. The sensor must be 10° off the horizontal to
ensure accuracy.

3. Do not install the sensor upside down.

4. Air bubbles may become trapped in the sensor end between the glass bulb and the sensor
body. This problem is most commonly encountered in areas of low flow or during calibration.
Shake the probe while immersed in solution to remove bubbles. This problem can be
avoided by ordering the sensor with the slotted tip (option 41).

In most cases, the pH sensor can simply be installed as shipped and readings with an accuracy
of ± 0.6 pH may be obtained. To obtain greater accuracy or to verify proper operation, the
sensor must be calibrated as a loop with its compatible analyzer or transmitter.

Installation 7

Section 2: Installation Instruction Manual

March 2017 LIQ-MAN-396P-396PVP

2.2.1 Flow Through and Insertion Mounting

osemount 396P and 396PVP Sensors have a 1-inch MNPT process connection at the front of

R
the sensor for mounting into a 1-1/2 inch tee or the process pipes. See Figure 2-2 through
Figure 2-7 for instal lation configurations.

NOTE: LARGE PIPE WRENCHES MUST NOT BE USED TO TIGHTEN THE SENSOR INTO A FLANGE
OR OTHER TYPE OF MOUNTING.

2.2.2 Submersion Mounting

Rosemount 396P and 396PVP Sensors also have a 1 inch MNPT process connection at the back
of the sensor. Utilizing a standard 1 inch union, the sensor may be mounted to a 1 inch SCH 80
CPVC or PVDF standpipe. Tapered pipe threads in plastic tend to loosen after installation. It is
therefore recom mended that Teflon1 tape be used on the threads and that the tightness of the
connection be checked frequently to assure that no loosening has occurred. To prevent rain
water or condensation from running into the sensor, a weatherproof junction box is recom­mended. The sensor cable must be run through a protective conduit for isolation from elec­trical interference or physical abuse from the process. The sensor should be installed within 80°
of vertical, with the electrode facing down. The sensor’s cable should not be run with power or
control wiring.

Section 3: Wiring

3.1 General

Figures in this section provide guidelines for wiring the Rosemount 396P/396PVP sensor to
various transmitters.

To determine which wiring guideline to use, locate the model number of the sensor to be
installed.

1. If the cable needs to be extended, use a high quality eleven conductor double shielded
instrument cable available from Rosemount. Refer to Table 3-1 for the appropriate junction
box to use and the corresponding wiring details.

NOTE: If the cable is too long, loop up the excess cable. If the cable has to be shortened, cut and
terminate each conductor neatly and make sure that the overall (outermost) drain wire is not
shorted out with either of the two inner drain wires (shields).

2. Signal cable should be run in a dedicated conduit (preferably an earth grounded metallic
conduit) and should be kept away from AC power lines. For your convenience, a wire nut kit is
furnished (in a plastic bag wrapped around the cable).

NOTE: For maximum EMI/RFI protection when wiring from the sensor to the junction box, the
outer braid of the sensor should be connected to the outer braided shield of the extension
cable. The outer braid of the extension cable to the instrument must be terminated at earth
ground or by using an appropriate metal cable gland fitting that provides a secure connection
to the instrument cable.

Wiring

The Rosemount 396P and 396PVP has an optional built-in preamplifier and is offered with a
shielded cable. The cable should be handled carefully and kept dry and free of corrosive chemi­cals at all times. Extreme care should be used to prevent it from being twisted, damaged or
scraped by rough, sharp edges or surfaces.

DANGER

DO NOT CONNECT SENSOR CABLE TO POWER LINES. SERIOUS INJURY MAY RESULT.

NOTE: Remove electrical tape or shrink sleeve from gray reference wire before connecting wire

to terminal.

LIQ-MAN-396P-396PVP March 2017

Section 4: Start-Up and Calibration

4.1 Rosemount 396P and 396PVP pH Sensors

4.1.1 Sensor preparation

Shake down the sensor to remove any air bubbles that may be present at the tip of the pH glass
bulb. In most cases, the pH sensor can simply be installed as shipped and readings with an accu­racy of ± 0.6 pH may be obtained. To obtain greater accuracy or to verify proper operation, the
sensor must be calibrated as a loop with its compatible analyzer or transmitter.

4.1.2 pH Calibration

After a temporary connection is established between the sensor and the instrument, a buffer
calibration may be performed. Consult appropriate pH/ORP analyzer or transmitter instruction
manual for specific calibration and standardization procedures, or see below for recommended
two-point buffer calibration procedure.

Recommended two-point buffer calibration procedure:

Select two stable buffer solutions, preferably pH 4.0 and 7.0 (pH buffers other than pH 4.0 and
pH 7.0 can be used as long as the pH values are at least two pH units apart).

NOTE: A pH 7.0 buffer solution reads a mV value of approximately zero, and pH buffers read
approximately 59.1 mV for each pH unit above or below pH 7.0. Check the pH buffer manufac­turer specifications for millivolt values at various temperatures since it may affect the actual
value of the buffer solution mV/pH value.

1. Immerse sensor in the first buffer solution. Allow sensor to adjust to the buffer temperature
(to avoid errors due to temperature differences between the buffer solution and sensor
temperature) and wait for reading to stabilize. Value of buffer can now be acknowledged by
analyzer/transmitter.

2. Once the first buffer has been acknowledged by the analyzer/transmitter, rinse the buffer
solution off of the sensor with distilled or deionized water.

3. Repeat steps 1 and 2 using the second buffer solution.

4. Once the analyzer/transmitter has acknowledged both buffer solutions, a sensor slope
(mV/pH) is established (the slope value can be found within the analyzer/ transmitter).

5. The slope value should read about 59.1 mV/pH for a new sensor and will decrease over time
to approximately 47-49 mV/pH. Once the slope reads below the 47-49 mV/pH range, a new
sensor should be installed to maintain accurate readings.

Recommended pH Sensor Standardization:

For maximum accuracy, the sensor can be standardized online or with a process grab sample
after a buffer calibration has been performed and the sensor has been conditioned to the
process. Standardization accounts for the sensor junction potential and other interferences.
Standardization will not change the sensor’s slope but will simply adjust the analyzer’s reading
to match that of the known process pH.

1. While obtaining a process solution sample (it is recommended that the sample is taken close
to the sensor), record the pH value that is shown on the analyzer/transmitter display.

Start-Up and Calibration 35

Section 4: Start-Up & Calibration Instruction Manual

March 2017 LIQ-MAN-396P-396PVP

2. Measure and record the pH of the process solution sample with another temperature
compensated, calibrated pH instrument. For best results, standardization should be

erformed at the process temperature.

p

3. Adjust the analyzer/transmitter value to the standardized value.

4.2 Rosemount 396P and 396PVP ORP Sensors

4.2.1 Sensor preparation

Most industrial applications have a number of ORP reactions occurring in sequence or simulta­neously. There can be several components that are oxidized or reduced by the reagents that are
used. Theoretically, the ORP potential is absolute because it is the result of the oxidation-reduc­tion equilibrium. However, the actual measured potential is dependent on many factors,
including the condition of the surface of the ORP platinum electrode. Therefore, the sensor
should be allowed 1-2 hours to become “conditioned” to the stream when first set-up or after
being cleaned.

4.2.2 ORP Calibration

1. Make a temporary electrical connection between the sensor and the instrument.

2. Obtain an ORP standard solution, or a standard solution can also be made quite simply by
adding a few crystals of quinhydrone to either pH 4 or pH 7 buffer. Quinhydrone is only
slightly soluble therefore a few crystals will be required. (Refer to Section 4.3. for an alter­nate ORP standard solution).

3. Immerse the sensor in the standard solution. Allow 1-2 minutes for the ORP sensor to stabi­lize.

4. Adjust the standardize control of the instrument to the solution value shown in Table 5-1
(below) or on the label of the standard solution. The resulting potentials, measured with a
clean platinum electrode and saturated KCl/AgCl reference electrode, should be within ±20
millivolts of the value. Solution temperature must be noted to ensure accurate interpretation
of results. The ORP value of saturated quinhydrone solution is not stable over long periods of
time. Therefore, these standards should be made up fresh each time they are used.

5. Remove the sensor from the buffer, rinse and install in the process.

Section 5: Maintenance

5.1 General Information

The Rosemount 396P and 396PVP Sensors require minimum maintenance. The sensor should
be kept clean and free of debris and sediment at all times. The frequency of cleaning by wiping
or brushing with a soft cloth or brush is determined by the nature of the solution being meas­ured. The sensor should be removed from the process periodically and checked in buffer solu­tions.

DANGER

BEFORE REMOVING THE SENSOR,be absolutely certain that the process pressure is reduced to 0 psig
and the process temperature is lowered to a safe level!

If the sensor will not calibrate, refer to your analyzer/ transmitter instruction manual for proper
test procedures. If it is determined that the sensor has failed, it

5.2 Automatic Temperature Compensator

The temperature compensator element is temp erature sensitive and can be checked with an
ohmmeter. Resistance increases with temperature.

The 3K element will read 3000 ohms ±1% at 25°C (77°F) and a Pt100 will read 110 ohms. Resist­ance varies with temperature for a 3K and Pt100 element and can be determined according to
Table 6-2 or the following formula:

RT=RO[l+R1(T-20)]

Where RT= Resistance

T = Temperature in °C

Refer to Table 6-1 for ROand R1values

5.3 Rosemount 396P and 396PVP pH Sensors

5.3.1 Electrode Cleaning

If the electrode is coated or dirty, clean as follows:

1. Remove the sensor from process.

2. Wipe the glass bulb with a soft, clean, lint free cloth or tissue. If this does not remove the dirt
or coating, go to Step 3. (Detergents clean oil and grease; acids remove scale.)

3. Wash the glass bulb in a mild detergent solution and rinse it in clean water. If this does not
clean the glass bulb, go to Step 4.

CAUTION

The solution used during the following check is an acid and should be handled with care. Follow the
directions of the acid manufacturer. Wear the proper protective equipment. Do not let the solution
come in contact with skin or clothing. If contact with skin is made, immediately rinse with clean water.

4. Wash the glass bulb in a dilute 5% hydro chloric acid solution and rinse with clean water.

Maintenance 37

Soaking the sensor overnight in the acid solution can improve cleaning action.

Section 5: Maintenance Instruction Manual

March 2017 LIQ-MAN-396P-396PVP

NOTE: Erroneous pH results may result immedi ately after acid soak, due to reference junction
potential build-up. Replace the sensor if cleaning does not restore sensor operation.

5.4 Rosemount 396P and 396PVP ORP

5.4.1 Platinum Electrode Check

The platinum electrode may be checked as follows: There are two types of standard solutions
which may be used to check the ORP electrode/transmitter system.

Type 1: One type of commonly used ORP standard solution is the saturated quinhydrone solu­tion. Refer to Section 5.2.

CAUTION

The solution used during the following check is an acid and should be handled with care. Follow the
directions of the acid manufacturer. Wear the proper protective equipment. If contact with skin of
clothing is made, immediately rinse with plenty of clean water.

Type 2: A second ORP standard solution is the Ferric-Ferrous Ammonium Sulfate Solution (PN

R508-16OZ), and it can be ordered as a spare part; otherwise, it can be prepared from the
following recipe: Dissolve 39.2 grams of reagent grade ferrous ammonium sulfate, Fe(NH4)2
(SO4)2 • 6H2O and 48.2 grams of reagent grade ferric ammonium sulfate, FeNH4(SO4)2 •
12H2O, in approximately 700 milliliters of water (distilled water is preferred, but tap water is
acceptable). Slowly and carefully add 56.2 milliliters of concentrated sulfuric acid. Add suffi­cient water to bring the total solution volume up to 1000 ml. This standard ORP solution,
although not as simple to prepare as the quinhydrone recipe, is much more stable, and will
maintain its millivolt value for approximately one year when stored in glass containers. This

solution (ferric/ferrous ammonium sulfate) will produce a nominal ORP of 476 +20 mV at 25°C
when used with a saturated KCl/AgCl reference electrode and platinum measuring electrode.
Some tolerance in mV values is to be expected due to the rather large liquid reference junction
potentials which can arise when measuring this strongly acidic and concentrated solution.

owever, if the measuring electrodes are kept clean and in good operating condition, consis-

H
tently repeatable calibrations can be carried out using this standard solution.

5.4.2 Cleaning Platinum Electrode

The electrode can be restored to normal operation by simply cleaning the platinum electrode
with baking soda. Polish it by rubbing it with a damp paper towel and baking soda until a bright,
shiny appearance is attained.
