Essential Instructions

Read this page before proceeding!

Emerson designs, manufactures and tests its products to meet many national and international stan-

dards. Because these sensors are sophisticated technical products, you MUST properly install, use,

nd maintain them to ensure they continue to operate within their normal specifications. The

a
following instructions MUST be adhered to and integrated into your safety program when installing,
using, and maintaining Rosemount products. Failure to follow the proper instructions may cause
any one of the following situations to occur: loss of life; personal injury; property damage; damage
to this sensor; and warranty invalidation.

• Read all instructions prior to installing, operating, and servicing the product.

• If you do not understand any of the instructions, contact your Emerson representative for
clarification.

• Follow all warnings, cautions, and instructions marked on and supplied with the product.

• Inform and educate your personnel in the proper installation, operation, and maintenance
of the product.

• Install your equipment as specified in the Installation Instructions of the appropriate
Instruction Manual and per applicable local and national codes. Connect all products to
the proper electrical and pressure sources.

• To ensure proper performance, use qualified personnel to install, operate, update,
program, and maintain the product.

• When replacement parts are required, ensure that qualified people use replacement parts
specified by Emerson. Unauthorized parts and procedures can affect the product's
performance, place the safe operation of your process at risk, and VOID YOUR WARRANTY.
Third-party substitutions may result in fire, electrical hazards, or improper operation.

• Ensure that all equipment doors are closed and protective covers are in place, except when

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.

WARNING

Do not exceed temperature and pressure limitations of 284 °F (140 °C) and 72 psig (600 kPa, 6 bar).

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

Internal electrolyte fill solution may cause skin or eye irritation.

CAUTION

Special Conditions for Safe Use

1. All pH 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.

. All pH sensor models are intended to be in contact with the process fluid and may not meet the 500V

2
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 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.

2.2 Storage

1. It is recommended that electrodes be stored in their original shipping containers until
needed.

2. Do not store at temperatures below 23 °F (-5 °C).

3. Electrodes should be stored with a protective cap containing KCl solution (PN 9210342).

4. For overnight storage, immerse the sensor in tap water or 4 pH buffer solution.

5. A pH glass electrode does have a limited shelf life of one year.

2.3 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 shake the electrode so that the internal
solution fills the bulb, thus removing any air trapped there.

Note: Do not allow lubricant to coat electrode bulb or reference junction. If it does, wipe it clean

before installation.

Instruction Manual Calibration

LIQ-MAN-3800 April 2017

Section 4: Calibration

4.1 Two Point Buffer Calibration

elect two stable buffer solutions, preferably pH 4.0 and 7.0 (pH buffers other than pH 4.0 and

S
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 sensor in the first buffer solution. Allow sensor to equilibrate 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. 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.

4.2 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.
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.

LIQ-MAN-3800 April 2017

Section 5: Maintenance

5.1 Maintenance

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

3. Temperature effect on life expectancy: If glass electrode life expectancy is 100% @ 25 °C
(77 °F), then it will be approximately 25% @ 80 °C (176 °F), and approximately 5% @ 120 °C
(248 °F).
