WARNING

Physical access

Unauthorized personnel may potentially cause significant damage to

and/or misconfiguration of end users’ equipment. This could be

intentional or unintentional and needs to be protected against.

Physical security is an important part of any security program and

fundamental to protecting your system. Restrict physical access by

unauthorized personnel to protect end users' assets. This is true for

all systems used within the facility.

CAUTION

Special conditions for safe use

All pH/ORP sensors have a plastic enclosure which must be cleaned

with a damp cloth to avoid the danger due to a buildup of

electrostatic discharge.

NOTICE

Sensor/process application compatibility

The wetted sensor material may not be compatible with process

composition and operating conditions.

Application compatibility is entirely the owner's responsibility.

4 Rosemount pH/ORP Sensors

2 Installation

2.1 Storing the sensor

•Emerson recommends storing pH/ORP sensors in their original

shipping containers until needed.

•Store sensors in a temperature-controlled environment.

•If the sensor must be stored after it has been removed from

its shipping container, store the sensor tip downward with the

protective cap in place and containing KCL solution (PN 9210342).

•For overnight storage, immerse the sensor in tap water or a 4 pH

buffer solution.

•pH glass electrodes slowly deteriorate in storage. There is no

specific expiration date. Follow the calibration procedures in

Calibration and maintenance to determine if the sensor calibrates

properly.

2.2 Prepare sensor

Procedure

1. Remove sensor from shipping container

2. Remove the protective cap covering the electrode bulb.

3. Rinse away salt film with clean water; then shake the electrode

so that the internal solution fills the bulb, removing any air

trapped there.

2.3 Installing sensors

2.3.1 Installation accessories

See the Liquid Analysis Sensor Mounting, Wiring, and Calibration

Product Data Sheet for a full list of accessories available from

Emerson to enable convenient and reliable sensor installation for

your application.

Quick Start Guide 5

2.3.2 Sensor orientation

Install all Rosemount pH/ORP sensors within 80 degrees of vertical,

as shown in Figure 2-1. This ensures that the air bubble within the

sensor does not stay at the sensor tip and disrupt the measurement.

Figure 2-1: Sensor orientation

Install the sensor tip down within 80 degrees of vertical.

2.3.3 Install insertion style sensors

Emerson offers two primary mounting styles for pH/ORP sensors:

insertion and retractable.

Insertion style sensors have NPT pipe threads that you can connect

directly into the process or into a mounting adapter.

Figure 2-2: Example of a Rosemount insertion style sensor

A. Forward facing ¾-in. NPT are present on some Rosemount pH/ORP

sensor models.

B. Forward facing 1-in. NPT

C. Wrench flats

D. Rear facing 1-in. NPT

You can connect insertion style sensors to the process using the

forward facing NPT threads or you can use the rear facing NPT

threads for immersion mounting in a pond or basin.

Quick Start Guide May2023

6 Rosemount pH/ORP Sensors

For immersion mounting, connect the sensor to a pipe using the rear

facing threads to keep the cable connection on the back of the sensor

dry.

Procedure

1. When using the sensor's NPT threads to connect to your

process, wrap the sensor threads with six or seven turns of

PTFE tape to prevent leakage.

2. Hand tighten the sensor and then tighten one or two turns

with a wrench.

Do not over tighten.

2.3.4 Installing retractable style sensors

Emerson offers two primary mounting style designs for pH/ORP

sensors: insertion and retractable.

Retractable style sensors have 1-in. (25 mm) outer diameter metal

bodies that you must connect to the process using an Emerson

provided insertion adapter or a ball valve retraction mounting

assembly.

Figure 2-3: Example of Rosemount retractable style sensor

A. 1-in. (25 mm) outer diameter retractable sensor body

Retractable sensors are available in several different lengths.

Retractable sensors with a length of less than 15 in. (381 mm) require

the use of an insertion adapter (PN 23166-00, PN 23166-01, or PN

9510066).

You can install retractable sensors with lengths greater than 15 in.

(381 mm) with an insertion adapter or with a Rosemount ball valve

assembly (PN 23240-00 or PN 23765-00). Ball valve assemblies allow

the sensor to be isolated from the process, so that you can remove

the sensor for cleaning, service, or replacement while the process

remains on-line.

C. Sensor body

Procedure

1. Slide the fitting onto the sensor from the back of the sensor.

Install the threads facing forward for insertion installations.

Install the threads facing backward for connection to a

submersion pipe.

2. Connect the NPT threads on the adapter to the process piping

or submersion pipe.

3. Adjust the position of the fitting on the sensor to achieve the

desired sensor insertion length.

4. While holding the sensor in position, tighten the hex nut of the

male connector to firmly secure the sensor in place.

NOTICE

Over-tightening the hex nut may damage the ferrule.

When you tighten the hex nut, the PTFE ferrule inside the

compression fitting clamps the sensor tube.

Procedure

1. Securely connect the ball valve assembly (ball valve, nipple,

and reducer) to the process.

2. Make sure the ball valve is closed and the system pressure is

at or below the maximum rated retraction pressure for the

sensor length you are using before proceeding.

WARNING

Before removing the sensor, be absolutely certain that the

process pressure is reduced to 0 psig (0 barg) and the

process temperature is lowered to a safe level.

Do not insert or retract retractable sensors when process

pressure is above the specified retraction pressure limit for

the length of sensor being used.

For 21-in. (533 mm) length sensors the maximum allowed

retraction pressure is 64 psig (5.4 barg).

For 36-in. (914 mm) length sensors the maximum allowed

retraction pressure is 35 psig (3.4 barg).

3. Slide the ferrule fitting (PN 23166-00 or 23166-01) onto the

sensor from the back of the sensor.

4. With the ferrule fitting on the sensor's body, insert the sensor

into the ball valve until it gently touches the closed valve.
