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.

WARNING

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!

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.

2.3 Retraction with Kit P/N 23240-00

WARNING

ystem pressure may cause the sensor to blow out with great force unless care is taken during removal.

S

2.3.1 Rosemount 3400HT/3400HTVP-21 (21 in. Tube)

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 2-1. 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).

2.3.2 Rosemount 3400HT/3400HTVP-25 (36 in. Tube)

1. 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 2-1. 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.

2. When the hex nut is loose enough, slowly ease the sensor back completely until the
retraction stop collar is reached.

NOTICE

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

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check that the sensor has been retracted to the retraction stop collar.

WARNING

Before removing the sensor from the ball valve, be absolutely certain that the ball valve is fully closed.
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
residual process fluid may leak from the connector's pipe threads.

4. The male connector body (A) may now be completely unthreaded from the reducing
coupling and the sensor removed for servicing.

NOTICE

If the male connector leaks during insertion or retraction, replace the O-ring (PN 23594-01) in the male
connector A.

20 Installation

Instruction Manual Startup and Calibration

LIQ-MAN-PERpH-X April 2017

Section 3: Startup and Calibration

3.1 Electrode Preparation

1. Remove electrode from shipping container.

2. Remove the protective boot covering the electrode bulb.

3. Rinse away salt film with clean water, then gently shake the electrode so that the internal
solution fills the bulb, thus removing any air trapped there.

CAUTION

The buffer in the protective boot may cause skin or eye irritation.

3.2 pH Sensor Calibration

3.2.1 Two Point pH Buffer Calibration

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 buffer solution reads a mV value of approx. zero, and pH buffers read

approximately ± 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 the sensor in buffer solution. The buffer solution must contact the metal housing
of the sensor which acts as the solution ground contact. Allow sensor to equilibrate to the
buffer temperature and wait for reading to stabilize. Value of buffer can now be
acknowledged by the 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. The theoretical slope value, according to the Nernst equation for calculating pH, is
approximately 59.17 mV/pH. Over time the sensor will age, both in the process and in
storage, and will result in reduced slope values. To ensure accurate readings, it is
recommended that the electrode be replaced when the slope value falls below
47 to 49 mV/pH.

3.3 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.
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.

Instruction Manual Maintenance

LIQ-MAN-PERpH-X April 2017

Section 4: Maintenance

4.1 Electrode Cleaning

lectrodes should respond rapidly. Sluggishness, offsets, and erratic readings are indicators that

E
the electrodes may need cleaning or replacement.

1. To remove oil deposit, clean the electrode with a mild non-abrasive detergent.

2. To remove scale deposits, soak electrodes for 30 to 60 minutes in a 5% hydrochloric acid
solution.

4.2 Reference Junction Replacement and Sensor
Electrolyte Recharge

The reference junction and reference fill gelled solution is replaceable to facilitate longer sensor life
due to electrolyte depletion and junction plugging and contamination. Use the junction
replacement kit and reference fill gel to accomplish this procedure.

1. Remove the junction cap by turning counter clockwise.

2. Remove the liquid junction by pulling the junction straight out.

CAUTION

The reference electrolyte may cause skin or eye irritation.

3. Remove the old reference fill gel by rinsing with water.

4. Fill the reference fill chamber with the reference fill gel using the syringe and remove any

air bubbles. Top off the reference fill chamber until it is completely filled.

5. Replace the junction O-ring and liquid junction by sliding over the glass electrode.

Excess reference gel should flow out.

6. Replace junction cap by turning clockwise. Hand tighten the junction cap only do not use

pliers to tighten the cap.

7. Buffer check and calibrate the sensor as described in the previous section.
