1. PREFACE

1.1 Introduction

This instruction manual provides information
for the installation and use of the SC25V,
combined 12mm glass sensor; pH, Ref, LE
and Temperature. The SC25V is the best
choice for the majority of typical process­and waste water applications. The sensor is
designed with titanium liquid earth, increased
electrolyte reservoir and large surface area PTFE
diaphragm combined with a long pathway inner
junction resulting in a longtime stability and
prolonged lifetime.

1.2 ATEX/IECEx compliance

The model SC25V is intended for use in
potentially explosive atmospheres. A number of
restrictions apply on the use of this sensor.
All varieties of SC25V are ATEX certified:
II1G Ex ia IIC T3...T6 Ga (see chapter 2.7).

EC-type Examination Certificate Number:

DEKRA 11ATEX0014 X

IECEx-type Examination Certificate Number:

IECEx DEK 11.0064x

Special conditions for safe use:

For ambient temperature see chapter 2.7.
Electrostatic charges on the enclosure and
cable shall be avoided.

1.3 Unpacking & Checking

Upon delivery, unpack the sensor carefully and
inspect it to ensure it was not damaged during
shipment. If damage is found, retain the original
packing materials (including outer box) and
immediately notify the carrier and the relevant
Yokogawa sales office. Make sure the Model
Code on the sensor is the same as on the
packing list. The Model Code and Serial Number
are found on the VP-connector of the sensor.
Check that option(s) that were ordered are also
included.

1.4 Warranty & Service

Yokogawa products and parts are guaranteed
free from defects in workmanship and materials
under normal use and service for a period of
twelve months from the date of shipment from
the manufacturer. Individual sales organizations
can deviate from the typical warranty period,
and the conditions of sales relating to the
original purchase order should be consulted.
Damage caused by wear and tear, inadequate
maintenance, corrosion, or by the effects of
chemical processes are excluded from this
warranty coverage. In the event of warranty
claim, the defective goods should be sent
(freight paid) to the Service Department of
the relevant sales Organization for repair or
replacement (at Yokogawa’s discretion).

The following information must be included in
the letter accompanying the returned goods:

• Model Code and Serial Number.

• Original Purchase Order and Date.

• Length of time in service and description of
the process.

• Description of the fault and circumstances of
the failure.

• Process/environmental conditions that may be
related to the failure of the sensor.

• Statement as to whether warranty or
nonwarranty service is requested.

• Complete shipping and billing instructions for
return of material, plus the name and phone
number of a contact person that can be
reached for further information.

Returned goods that have been in contact with
process fluids must be decontaminated
and disinfected prior to shipment. Goods
should carry a certificate to this effect, for the
health and safety of our employees. Material
Safety Data sheets must be included for all
components of the process to which the
sensors/fittings have been exposed.

3. INSTALLATION

3.1 Typical installation

The SC25V sensor can be installed in-line, in a
bypass loop or in an immersion assembly. For
best results the SC25V should be mounted with
the process fluid flowing towards the sensor
and positioned at least 15° above the horizontal
plane to eliminate air bubbles in the glass bulb.
See fig. 6 section 3.3

3.2 Preparing the sensor for use

Remove the sensor from its shipping box and
slide off the “wet pocket” (the flask including the
rubber ring). This wet pocket is filled with a weak
acid and saline solution to prevent the sensor
from drying out during storage and making sure
it is ready for immediate use.

Before mounting the sensor, it should be
validated with buffer solutions and calibrated
when necessary. The specific calibration
procedure is described in the Instruction Manual
of the pH transmitter, but a general procedure is
also provided in section 5 of this manual.

3.3 Mounting the sensor

The SC25V can be mounted using:

• PR10 retractable fitting (see fig 2).

• FF20 flow fitting / FS20 subassembly / FD20
immersion fitting (see fig 4)

• For mounting in Yokogawa fittings, a PG13.5
to M25 adapter is available in different
materials (see fig 3) more information in
chapter 7.

• PD20 immersion fitting / PF20 flow fitting /
PS20 flow fitting (see fig 5)

• FF40 fitting with PG13,5 adapter (K1523JA)
or the small flow fitting K1598AC with PG13,5
adapter (K1523JB), (see fig 7).

5. GENERAL CALIBRATION AND MAINTENANCE PROCEDURE

5.1 Calibration for pH measurement

To calibrate a pH sensor, at least two buffer
solutions with known pH values are required. It
is recommended to use one buffer solution with
a value of pH=7. The second buffer solution
should be either acidic (pH<7) or alkaline
(pH>7), depending on the process value to be
measured. Example buffer solutions are the IEC
buffers with pH=4.01, pH=6.87 and pH=9.18.

The following is a general 2-point calibration
procedure:
1 Clean the sensor (deposits may be removed

using a 5% HCl-solution).

2 Rinse sensor thoroughly with clean water.

Carefully slap out residual fluid drops.

3 Immerse the sensor in the first buffer (pH=6.87

buffer is recommended).

4 Refer to appropriate Instrument Instruction

Manual for detailed instrument calibration input
settings (Auto; Manual; Sample, etc.),

5 Rinse sensor thoroughly with clean water.

Carefully slap out residual fluid drops.

6 Immerse the sensor in the second buffer

(pH=4.01 buffer or pH=9.18 buffer
recommended).

7 Repeat Step 3.

Most instruments automatically correct the
measured pH value at process temperature to
a pH-value at a standard temperature of 25°C.
After the calibration is complete, replace or
re-install the sensor into the process.

5.2 Maintenance

Cleaning the electrodes

When the sensitivity of the electrode has
decreased or the response has slowed down,
the electrode should be cleaned. If cleaning
with hot water is not sufficient, more aggressive
water based agents should be used.

Examples:

• Deposits of lime, hydroxides or carbonates
can be removed by immersing the sensor in
or a dilute solution of hydrochloric acid (5% is
recommended). Afterwards rinse with water.

• Deposits of oils and fats can be removed with
hot water in conjunction with a detergent.

When the results are unsatisfactory, a mild
(carbonate based) abrasive can be used.

IM12B6J1-40E-E

5.3 Chemical cleaning HCN

The chemical cleaning system is effective in
processes where deposits can be removed by
a suitable solvent. Good cleaning effects can
be obtained from periodically spraying of an
electrode. EXA PH450G has a built-in wash
timer with programmable wash time, interval
time and relaxation time for automatic cleaning
of the electrodes, preventing pollution of the
pH sensitive parts. After washing, it is possible
to check the response time of the electrodes.
A built-in (no return) nozzle in the spray unit
prevents penetration of the process liquid in the
cleaning system. The standardized dimensions
allow mounting in all flow-, insertion- and
immersion fittings of Yokogawa as well as
back-end mounting on the 4-in-one pH/Redox
electrodes.
