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

WARNING

Retractable sensors must not be inserted nor retracted when process pressures are in excess of 64 psig
(542kPa) for option 21 or 35 psig (343 kPa) for option 25.

CAUTION

Special Conditions for Safe Use

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

1
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 1: Description and Specifications

1.1 Features and Applications

Rosemount 396R and 396RVP Sensors are specifically designed for improved life in harsh, dirty
applications where a separate sample stream is difficult to provide and greater insertion depths are
required. These sensors are designed for use with a 1-1/4 in. or 1-1/2 in. ball valve for hot tap
installation. Sensors are constructed of molded polypropylene housed in a titanium tube with EPDM
seals to provide maximum chemical resistance. The sensors feature a shrouded tip for protection
from breakage while allowing process to flow by the glass electrode for accurate and reliable pH
and ORP measurements.

Figure 1-1: Cross Section Diagram of the TUpH Reference Technology

All TUpH sensors are designed with a large area reference junction, helical reference pathway, and an
AccuGlass pH glass bulb. This sensor technology ensures superior performance while only requiring
minimal maintenance.

2.2 Unpacking and Inspection

Inspect the outside of the carton for any damage. If damage is detected, contact the carrier
immediately. Inspect the instrument and hardware. Make sure all items in the packing list are
present and in good condition. Notify the factory if any part is missing.

Note: If the sensor is to be stored, the protective boot should be filled with either KCl electrolyte
solution or pH 4.0 buffer solution and replaced on sensor tip until ready to use.

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 instrument to the factory, you must pack the
instrument in the same manner as it was received. Refer to Section 8.0 for instructions.

WARNING

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

2.3 Mechanical Installation

The Rosemount 396R Sensor may be installed through a weldalet or in a pipe tee or “Y”, as shown
in Figure 2-1, when used with a ball valve. Insert the end of the sensor to a depth sufficient to ensure
that the glass bulb is continuously wetted by the process fluid. The Rosemount 396R can also be
inserted directly into the process without the use of a ball valve for appli cations not requiring
continuous operation during sensor maintenance.

CAUTION

Allow sufficient room for safe retraction and insertion of the sensor. Personnel should have room for
stable footing while performing removal or insertion of the sensor.

The sensor must be mounted within 10-90 degrees of the horizontal with the tip pointed
downward, thus keeping air bubbles off of the pH sensitive glass bulb. Bubbles settled on the glass
bulb disrupt the electrical continuity between the pH sensitive glass and the silver/ silver chloride
measuring element.

If the retraction version is to be installed without a ball valve follow the installation procedure for
insertion service (Section 2.3.2). Perform the following steps for sensor installation through a ball
valve:

2.3.1 Installation Through Ball Valve

1. Carefully remove the liquid filled rubber boot which protects the glass electrode and keeps
the liquid junction wet during shipping and storage. Discard the liquid and boot. Make sure
the lubricated O-ring is in place in the groove inside the male connector on the sensor body.

CAUTION

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

2. With the male connector on the sensor’s body, insert the sensor into the ball valve until it
gently touches the closed valve. The molded electrode guard will protect the glass bulb
from breakage.

8 Installation

Instruction Manual Installation

LIQ-MAN-396R-396RVP March 2017

3. Thread the male connector body tightly into the ball valve assembly. DO NOT tighten the
hex nut on the male connector body; doing so would not allow the sensor to be inserted
through the ball valve.

4. Pull back hard on the sensor assembly, as if trying to remove the sensor, to be certain that
the sensor cannot come free of the ball valve assembly. The built-in retraction stop will butt
against the shoulder of the male connector if properly installed.

CAUTION

The sensor must be captured by the valve assembly and the male connector so that it cannot be blown
free by process pressure if mishandled during insertion or retraction.

5. After confirming that the sensor assembly is properly secured by the valve assembly, the
valve may be opened and the sensor positioned into the process at the desired depth and
orientation.

6. While holding the sensor in position, tighten the hex nut of the male connector to firmly
secure the sensor in place. When the hex nut is tightened, the Teflon ferrule inside the
compression fitting clamps the sensor tube.

CAUTION

Over tightening the hex nut may damage the ferrule.

NOTICE

A stainless steel ferrule is available if the Teflon ferrule does not inadequately grip. When using the
metallic ferrule, care must be taken to avoid over tightening and damaging the sensor tube. If the male
connector leaks during insertion or retraction, replace the O-ring in the male connector.

2.3.2 Installation Without Ball Valve

The Rosemount 396R Sensor may be installed through a weldalet or pipe tee or “Y” when used with
a process connector (PN 23166-00 or 23166-01). The sensor should be installed within 80° of
vertical, with the electrode facing down.

3.1 Wiring for Rosemount 396RVP

Make electrical connections as shown on Figures 4-1 through 4-20 using the following guidelines.
For wiring Rosemount 396R, see Section 3.

1. Pay particular attention to the analyzer or transmitter model number when following
details on the wiring diagrams to ensure that the connections are made to the proper
terminals.

2. The Rosemount 396RVP uses a mating VP cable. See attached wiring sheet for wire
functions of the cables and wiring diagrams to various transmitters.

3. The maximum distance from the sensor to the transmitter is 15 ft without an integral
preamplifier.

4. Signal cable should be run in a dedicated conduit and should be kept away from AC power
lines.

NOTICE

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.

Section 5: Startup and Calibration

5.1 Sartup

To obtain best accuracy, the sensor must be calibrated as a loop with the transmitter. Please refer
to the respective transmitter instruction manual for proper calibration procedures.

5.2 pH Calibration

1. After a temporary connection is established between the sensor and the instrument, a
buffer calibration may be performed.

2. Consult appropriate pH/ORP transmitter instruction manual for specific calibration and
standardization procedures or see below for recommended two point buffer calibration
procedure.

5.2.1 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).

NOTICE

A pH 7 buffer solution reads a mV value of approx. zero, and pH buffers read approx. +/- 59.1 mV for each
pH unit above or below pH 7. 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 transmitter.

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

Startup and Calibration 43

Startup and Calibration Instruction Manual

March 2017 LIQ-MAN-396R-396RVP

5.2.2 Recommended pH Sensor Standardization

For maximum accuracy, the sensor can be standardized on-line or with a process grab sample after
a buffer calibration has been performed and the sensor has been conditioned to the process.

tandardization accounts for the sensor junction potential and other interferences.

S
Standardization will not change the sensor’s slope but will simply adjust the transmitters 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 transmitter display.

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

3. Adjust the transmitter value to the standardized value.

5.3 ORP Calibration

An ORP loop is best calibrated using an ORP standard solution. 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.

5.3.1 ORP Calibration Procedure

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

2. Obtain a ORP standard solution (PN R508-8oz) or one can 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, only a few crystals will be required.

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.
The resulting potentials, measured with a clean platinum electrode and saturated KCl/AgCl
reference electrode, should be within ±20 millivolts of the value shown in Table 5-1.
Solution temperature must be noted to insure 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.

LIQ-MAN-396R-396RVP March 2017

Section 6: Maintenance

6.1 Maintenance

osemount 396R and 396RVP sensors are disposable type sensors and require minimum

R
maintenance. These sensors should be removed from the process periodically and checked in buffer
solutions. If the sensor will not calibrate, refer to your transmitter instruction manual for proper
test procedures. If the sensor has failed, it should be discarded and replaced.

6.2 Sensor Removal

Please refer to the appropriate paragraph for instructions regarding removal of the sensor for
periodic maintenance.

6.2.1 Retractable Version

WARNING

System pressure may cause the sensor to blow out with great force unless care is taken during removal.
Make sure the following steps are adhered to.

A. Rosemount 396R-21 (21 in. tube)

1. Be certain system pressure at the sensor is below 64 psig (542 kPa) before

proceeding with the retraction. It is also recommended that the personnel wear
a face shield and have a stable footing. Refer to Figure 6-1. Push in on the sensor
end or the top of the J-box and slowly loosen the hex nut (B) of the process end
male connector (A).

B. Rosemount 396R-25 (36 in. tube)

2. Be certain that pressure at the sensor is below 35 psig (343 KPa) before proceeding

with the retraction. It is also recommended that the personnel wear a face shield
and have a stable footing. Refer to Figure 6-1. Push in on the sensor end or the top
of the J-box and slowly loosen the hex nut (B) of the process end male
connector (A).

CAUTION

Do not remove nut at this time.

3. When the hex nut is loose enough, slowly ease the sensor back completely until

the retraction stop collar is reached.

CAUTION

Failure to withdraw the sensor completely may result in damage to the sensor when the valve is closed.

4. Close the ball valve slowly. If there is resistance, the valve may be hitting the

sensor. Double check that the sensor has been retracted to the retraction stop
collar.

Maintenance 45

Maintenance Instruction Manual

March 2017 LIQ-MAN-396R-396RVP

WARNING

efore removing the sensor from the ball valve, be absolutely certain that the ball valve is fully closed.

B
Leakage from the male connector threads may indicate that the male connector is still under pressure.
Leakage through a partially open valve could be hazardous, however with the ball valve closed, some

esidual process fluid may leak from the connector's pipe threads.

r

5. The Male Connector Body (A) may now be completely unthreaded from the

reducing coupling and the sensor removed for servicing.

CAUTION

If the male connector leaks during insertion or retraction, replace the O-ring (PN 9550099) in the male
connector A.

6.3 pH Electrode Cleaning

If the electrode is coated or dirty, it may be cleaned as follows:

1. Remove the sensor from process as instructed in Section 6.2.

2. Wipe the glass bulb with a soft, clean, lint free cloth or tissue. If this does not remove the
dirt or coating, proceed to step 3. If the sensor appears to be clean, go to step 5.

3. Wash the glass bulb in a strong detergent solution and thoroughly rinse with tap water. If
the bulb still appears to have a coating, proceed to step 4.

CAUTION

The solution used in the following step 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 the skin is made, immediately rinse with clean water.

4. Following the caution above, wash the glass bulb in dilute 5% hydrochloric acid solution
and then rinse it thoroughly in tap water. Replace the sensor if it cannot be cleaned. If the
glass bulb appears clean, proceed to step 5.

5. Buffer calibrate the sensor (Refer to Section 5). If the sensor appears to respond
sluggishly to pH change, soaking it overnight in a weak acid solution (5% hydrochloric acid)
may improve its response. Be sure to follow the CAUTION above and to rinse the sensor’s
tip thoroughly with tap water. If the sensor will not calibrate, it must be replaced.

6.4 Cleaning Platinum Electrode

The electrode is never exposed to these undesirable compounds. In the event poisoning is
suspected, 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.

6.6 Sensor Tube Replacement When Used With A
Sensor Head Junction Box

Replace ment of the retraction versions sensor tube assembly involves the removal and installation
of two sets of male connectors: One at the process end of the sensor, and the other at the junction
box end (See Figures 6-1, 6-2). Refer to Section 6.2 for proper removal of the sensor from process.

1. Remove sensor from process before proceeding. The junction box with attached male

connector must be recovered from the old sensor for reuse. Unscrew the junction box cover
and set aside. Disconnect electrical connections from printed circuit board inside junction
box. Disconnect BNC connector to preamp. Unscrew hex nut (D) from male connector
body (C). Separate junction box from used sensor. Set aside.

2. Pry off split ferrule from sensor and set aside for reuse. Remove hex nut (D) and set aside

for reuse. Check that the internal O-ring is in place in the male connector body (C) attached
to the junction box.

3. Remove hex nut (B) from male connector body (A) at process end of sensor and set aside.

Slide the Teflon ferrule and the male connector off sensor in the direction of junction box
and set.

NOTICE

If stainless steel ferrule was used, male connector body (A) will have to be discarded with the sensor tube.

4. Discard used O-ring from male connector body (A). Coat new O-ring with a thin film of the

O-ring lubricant provided. Position it in the machined Oring groove in place of the
discarded O-ring.

CAUTION

Make sure lubricant does not contact any part of the sensor tip particularly the glass bulb.

5. Cover the 1" MNPT pipe threads of the male connector body (A) with Teflon tape (not

provided) to protect them from galling during reinstallation.

6. Pass the wires from the new sensor through the process end male connector (A). Make

sure that the beveled edge of the ferrule faces the process end of the sensor. Snug the hex
nut (B) to keep it in place. Do not tighten down fully on the hex nut at this time.

7. Pass the wires from the new sensor through the hex nut (D), the split ferrule (from the old

sensor), male connector body (C), O-ring, and through the junction box from the “neck”
opening and out to the printed circuit board in the junction box. Butt the ferrule’s beveled
edge and the sensor tube against the junction male connector (C). Screw the hex nut (D)
by hand until the tube is “locked” into the male connector body. Make sure that the male
connector body (C) is sufficiently tightened. The sensor will “click” into place by pulling
the sensor tube away from the junction box, but will not move from side to side or pull
clear of the male connector. If the sensor tube is correctly attached to the junction box,
wrench tighten hex nut (D) on male connector body (C) (see Figure 6-1). Do not put the
sensor tube in a vise or use a pipe wrench to tighten the hardware as these will damage
the sensor. If sensor tube is not correctly attached to the junction box, loosen hex nut (D)
and repeat.

48 Maintenance

Instruction Manual Maintenance

LIQ-MAN-396R-396RVP March 2017

8. Connect the sensor wires to the terminals on the printed circuit board in the junction box

n the manner recommended on the junction box cover,and reattach the BNC connector

i
to the preamp. Screw on the cover of the junction box aside. Discard sensor tube.

9. Insert the sensor in the process fitting. Stop it against the closed ball valve. Slide the

processend male connector down the sensor tube to mate with the process fitting. Tighten
the male connector into the process fitting.

10. Pull back hard on the sensor assembly, as if trying to remove the sensor, to be certain that

the sensor cannot come free from the valve assembly and male connector. The built-in
retraction stop collar at the end of the sensor will butt against the shoulder of the male
connector.

11. Open ball valve and position the sensor at the desired insertion depth and orientation.

Using a crescent or open end wrench, tighten the hex nut (B) to secure the sensor in place.
See Figure 6-2.

NOTICE

A stainless steel ferrule is available if the Teflon ferrule does not adequately grip, be careful and avoid over
tightening. This can damage the sensor tube.

CAUTION

If the male connector leaks during insertion or retraction, replace the O-Ring (PN 9550099) in the male
connector body (A).

If the sensor is to be stored, the rubber boot should be filled with 7pH buffer solution and replaced
on sensor tip until ready to use.
