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 main­tenance is being performed by qualified persons, to prevent electrical shock and personal injury.

The information contained in this document is subject to change without notice.

DANGER

Hazardous Area InstallationN

Installations near flammable liquids or in hazardous area locations must be carefully evaluated by
qualified on site safety personnel.

To secure and maintain an intrinsically safe installation, the certified safety barrier, transmitter, and
sensor combination must be used. The installation system must comply with the governing approval
agency (FM, CSA or BASEEFA/CENELEC) hazardous area classification requirements. Consult your
transmitter instruction manual for more details.

Proper installation, operation and servicing of this sensor in a Hazardous Area Installation is entirely
the responsibility of the user.

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.

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.

1.3 Ordering Information

The Rosemount 396P Sensor is housed in a molded
reinforced polypropylene body with 1 in. MNPT threads
suitable for insertion, submersion or flow through
installation. The sensor includes a general purpose pH
electrode or a platinum ORP electrode, a reference junc­tion and a solution ground. The Rosemount 396P comes
standard with a recessed electrode; an optional slotted
tip is also available. In addition, the Rosemount 396P
features an optional integral hermetically sealed pream­plifier and 15 ft or 25 ft cable lengths. Automatic temper­ature compensation, Pt 100 or 3K Balco, is standard with
the Rosemount 396P.

The Rosemount 396PVP Sensor has similar features to
the Rosemount 396P. However, the Rosemount 396PVP
is offered with the Variopol (VP) connector and uses a
mating VP cable (purchased separately).

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 hardware. Make sure all the items in the packing list are present and in
good condition. Notify the factory if any part is missing. If the sensor appears to be in satisfac­tory condition, proceed to Section 2.2, Mounting.

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 sensor to the factory, you must
pack the sensor in the same manner as it was received. Refer to Section 6.0 for return instruc­tions. If the sensor is to be stored, the vinyl boot should be filled with pH buffer solution and
replaced on sensor tip until ready to use.

CAUTION

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

WARNING

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

2.2 Mounting

The sensor has been designed to be located in industrial process environments. Temperature
and pressure limitations must not be exceeded at any time. A caution label regarding this
matter is attached to the sensor. Please do not remove the label. See Figure 2-1.

CAUTION

Internal electrolyte fill solution may cause skin or eye irritation.

Mounting Guidelines:

1. Shake the sensor in a downward motion to remove any air bubbles that may be present
inside the tip of the pH glass.

2. Do not install the sensor on the horizontal. The sensor must be 10° off the horizontal to
ensure accuracy.

3. Do not install the sensor upside down.

4. Air bubbles may become trapped in the sensor end between the glass bulb and the sensor
body. This problem is most commonly encountered in areas of low flow or during calibration.
Shake the probe while immersed in solution to remove bubbles. This problem can be
avoided by ordering the sensor with the slotted tip (option 41).

In most cases, the pH sensor can simply be installed as shipped and readings with an accuracy
of ± 0.6 pH may be obtained. To obtain greater accuracy or to verify proper operation, the
sensor must be calibrated as a loop with its compatible analyzer or transmitter.

Installation 7

Section 2: Installation Instruction Manual

March 2017 LIQ-MAN-396P-396PVP

2.2.1 Flow Through and Insertion Mounting

osemount 396P and 396PVP Sensors have a 1-inch MNPT process connection at the front of

R
the sensor for mounting into a 1-1/2 inch tee or the process pipes. See Figure 2-2 through
Figure 2-7 for instal lation configurations.

NOTE: LARGE PIPE WRENCHES MUST NOT BE USED TO TIGHTEN THE SENSOR INTO A FLANGE
OR OTHER TYPE OF MOUNTING.

2.2.2 Submersion Mounting

Rosemount 396P and 396PVP Sensors also have a 1 inch MNPT process connection at the back
of the sensor. Utilizing a standard 1 inch union, the sensor may be mounted to a 1 inch SCH 80
CPVC or PVDF standpipe. Tapered pipe threads in plastic tend to loosen after installation. It is
therefore recom mended that Teflon1 tape be used on the threads and that the tightness of the
connection be checked frequently to assure that no loosening has occurred. To prevent rain
water or condensation from running into the sensor, a weatherproof junction box is recom­mended. The sensor cable must be run through a protective conduit for isolation from elec­trical interference or physical abuse from the process. The sensor should be installed within 80°
of vertical, with the electrode facing down. The sensor’s cable should not be run with power or
control wiring.
