1.3 Retraction with kit PN 23240-00

WARNING

System pressure may cause the sensor to blow out with great force.

Take care when removing the sensor.

1.3.1 Retract Rosemount 3400HT/3400HTVP-21 (21-in. [533.4 mm] tube)

WARNING

Be certain the system pressure at the sensor is below 64 psig (542 kPa
[abs]) before retracting the sensor.

Wear a face shield.
Make sure your footing is stable.

Procedure

Push in on the sensor at the top of the junction box and slowly loosen the
hex nut of the process end male connector.

1.3.2 Retract Rosemount 3400HT/3400HTVP-25 (36-in. [914,4 mm]) tube

WARNING

Be certain the system pressure at the sensor is below 64 psig (542 kPa
[abs]) before retracting the sensor.

Wear a face shield.
Make sure your footing is stable.

Procedure

1. Push in the sensor end or the top of the junction box and slowly
loosen the hex nut of the process end male connector.

CAUTION

Do not remove nut at this time.

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

Quick Start Guide 17

Quick Start Guide November 2020

CAUTION

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check that the sensor has been retracted to the retraction stop collar.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

Leakage from the male connector threads may indicate that the
male connector is still under pressure.

Leakage through a partially open ball valve could be hazardous;
however, with the ball valve closed, some residual process fluid may
leak from the connector's pipe threads.

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

4. Unthread the male body connector completely from the reducing
coupling and remove the sensor for servicing.

Note

If the male connector leaks during insertion or retraction, replace the
O-ring (PN 25394-01) in the male connector.

November 2020 Quick Start Guide

2 Start up and calibrate

2.1 Prepare electrode

Procedure

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.

WARNING

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

2.2 Calibrate with two point pH buffer solution

Select two stable buffer solutions, preferably pH 4.0 and pH 7.0. You can use
buffers other than pH 4.0 and pH 7.0 as long as the pH values are least two
pH units apart.

Note

A pH 7 buffer solution reads an mV value of approximately 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 milivolt values at
various temperatures, since temperature may affect the actual value of the
pH buffer solution mV/pH value.

Procedure

1. Immerse the sensor in buffer solution.
Make sure the buffer solution contacts the metal housing of the

sensor, which acts as the solution ground contact.

2. Allow sensor to equilibrate to the buffer temperature and wait for the
reading to stabilize.
The transmitter can now acknowledge the value of the buffer.

3. Rinse the buffer solution off of the sensor with distilled or deionized
water.

4. Repeat steps Step 1 through Step 3 using the second buffer solution.

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 this will result in reduced slope values. To

Quick Start Guide 25

Quick Start Guide November 2020

ensure accurate readings, Emerson recommends replacing the electrode
when the slope value falls below 47 to 49 mV/pH.

2.3 Standardize pH sensor

For maximum accuracy, you can standardize the sensor in-line or with a
process grab sample after performing a buffer calibration and conditioning
the sensor to the process. Standardization accounts for the sensor junction
potential and other interferences. Standardization does not change the
sensor's slope, but simply adjusts the transmitter's reading to match that of
a known process pH.

November 2020 Quick Start Guide

3 Maintenance

3.1 Clean electrodes

Electrodes should respond rapidly. Sluggishness, offsets, and erratic
readings are indicators that you may need to clean or replace the electrodes.

Procedure

1. To remove oil deposits, clean the electrodes with a mild, non­abrasive detergent.

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

3.2 Replace reference junction and recharge sensor electrolyte

The reference junction and reference fill gelled solution are replaceable to
facilitate longer sensor life. Over time, the electrolyte depletes and the
junction may become plugged or contaminated.

Prerequisites

Use the junction replacement kit and replacement fill gel.

Procedure

1. Remove the junction cap by turning it counter clockwise.

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

WARNING

The reference electrolyte may cause skin or eye irritation

Avoid contact with skin and eyes.

3. Rinse with water to remove the old reference fill gel.

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 them 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.

Quick Start Guide 27

parts may provide an electrostatic ignition hazard and must only be
cleaned with a damp cloth to avoid the danger of ignition due to
build-up of electrostatic charge.

2. All pH/ORP sensor models with a metallic enclosure may provide a
risk of ignition by impact or friction. Care should be taken during
installation to protect the sensor from the risk.

3. External connections to the sensor must be suitably terminated and
provide a degree of protection of at least IP20.

4. All pH/ORP sensor models are intended to be in contact with the
process fluid and may not meet the 500V r.m.s. test to earth. This
must be taken into consideration at installation.
