1. INTRODUCTION
1-1. Description
The retractable fitting with ball valve allows
a safe insertion and retraction of a sensor
while the process is under pressure. It can
be mounted in a variety of positions. The
insertion depth can be chosen on site. An
insertion stop is provided to set the
position of the sensor in the process.
The mechanism for releasing the probe is
designed to operate only when the ball
valve is closed, thus ensuring an effective
safety precaution. The sensor can be
replaced or calibrated easily.
1-2. Features
GA safe “through the valve” insertion and
retraction design.
GAdditional safety through a special
designed T-bar locking mechanism.
GMaintenance, replacement and
calibration of the sensor without
interruption of the process.
GAdjustable insertion depth for optimal
measuring position in the process.
GReplacement of the sensor.
GImproved sealing and damping by
additional o-rings.
GSimplified installation by optional ball
valves with flanged or tapered
connections.
GAvailable in 0.5 and 1 metre probe
length in two different materials.

3. INSTALLATION
3-1. Unpacking and checking
When you receive the ISC40PR retractable
fitting it is packed in a cardboard box.
Open the box and check that the model
code on the fitting is the same as the one
on the packing list. See §2-2 for the model
code. Also check that it is supplied with the
options you ordered.
The options can be delivered in separate
boxes. If you have any problems or
questions, contact your nearest Yokogawa
service centre or sales organisation for
support.
The ISC40PR retractable fitting has an
identification plate on the protection ring
with the full model code and a serial
number.
3-2. Installation site
The ISC40PR fitting is intended to be used
for in-line conductivity measurement. When
it is delivered with an optional ball valve or
when it is used in combination with a
locally purchased ball valve, the process
need not be interrupted for maintenance of
the sensor.
The location can be in a large diameter
pipeline or a vessel.
3-3. Safety precautions
The ISC40PR fitting has been designed to
give maximum safety in operation. For
optimum safety a flanged ball-valve is
recommended.
Yokogawa does not accept any claims or
penalties on possible damages or
accidents which occurred by operation of
the ISC40PR fitting.
The installation of the probe is to be
implemented under the local safety
regulations for pressurised vessels or pipe
lines for retraction or insertion.
The instructions given in this manual must
be followed exactly.
3-4. Installation method
It is important to have the point of
measurement in a location that is truly
representing the process composition.
Check whether the specifications of the
sensor fulfil the maximum occurring
process conditions. The fitting has several
optional connection possibilities. Check
that you received the correct size and type.
Install the fitting in a convenient location for
maintenance and calibration. For
maintenance or calibration the probe will
need a space of about 2 metre for total
retraction (depending on probe length and
optional adapters and/or ball valves).
Installation in a bend of a pipe line is a
good measurement position. When
inserting the ISC40PR retractable fitting in
a perpendicular position to the process
flow, the flow velocity will put a mechanical
force on the probe. Take care that this
force is not too large.
Note:
Do not insert the fitting into the process
without the sensor mounted! The sensor
is delivered separately in a box.
Start with the assembly of the sensor into
the probe and follow the instructions for
the preparation of a new sensor. See §3-8.
3-5. Assembly of accessories
Optional accessories are (mostly) delivered
separately in boxes.
When a ball valve is ordered as an option,
this should be mounted to the measuring
position first. When the ball valve is in
place, the process line is secure.
If the ball valve has a tapered connection, it
needs to be locked with glue.
Next the adapter at the other side of the
ball valve needs to be mounted. This
adapter has ISO 228/1-G2 male thread at
one side and a matching connection for the
ball valve at the other side. Mount the
adapter on the ball valve and lock it with
glue.

3-9. Mounting the sensor into the
fitting
1. Take the sensor out of the box and
remove the cable tie carefully.
2. Bind the separate wires of the cable
together with a piece of tape.
3. Take the fitting out of the box and
remove the option(s), if necessary.
4. Screw the knurled knob out off the
fitting
5. Release the pigtail (cable gland)
completely. Do not undo the part in the
metal tube!
6. Lead the sensor cable through the
tube of the fitting, from the side where
the knurled knob has been removed.

SCREWING INTO TUBE
6. Hold the sensor still and turn the metal
tube onto the sensor.
Don’t rotate the cell, but rotate the
tube of the fitting, because the cable
can be disconnected from the cell,
when rotating it.
7. Lead the loose part of the pigtail onto
the cable and screw it onto the fixed
part.
8. Remove the tape.
9. Retain the knurled knob for future use
or discard.
It is not necessary while the fitting is
installed.

3-10 Probe insertion
1. Position the probe for insertion.
2. Turn the T-bar key clockwise.
3. Open the ball valve.
4. Push the probe into the process.
5. Fix the probe by turning the fixing
screw clockwise.
Remarks:
- Turning the T-bar key can only be done
when the valve is closed.
FIXING SCREW
1
- Pushing the probe into the process needs
a force to overcome the pressure of the
system and the friction of the dampening
rings in the fitting.
- The locking mechanism can be tightened
until the probe is firmly fixed at the
measuring position.
- The insertion stop can be fixed at the
actual insertion position. See §3-10 on
adjusting the insertion depth.

3-11. Adjusting the insertion depth
The insertion depth of the sensor can be
adjusted to your preference.
The insertion stop can be set for at the
actual insertion position of the probe. The
“Allan” key, supplied with the fitting, is used
to fix the insertion stop at the desired
position.
The maximum insertion depth is related to
the probe length mentioned in the model
code of the fitting.

4. MAINTENANCE
4-1. General
Before the sensor can be serviced, the
probe with the sensor inside should be
physically separated from the process.
The ISC40PR retractable fitting can be
retracted from its measuring position in the
maintenance position by following the five
step procedure mentioned in §3-9 in
reverse order.
4-2. Taking out the sensor
Retract the probe from the process
according to the following procedure:
1. Release the fixing screw.
2. Pull out the probe.
3. Close the ball valve (*).
4. Turn the T-bar counter clockwise
5. Take out the probe.
* : If the option drain port is available, the
process pressure can be relieved before
removing the sensor.
Remarks:
- Stand clear when releasing the fixing
screw! Due to the process pressure the
probe can be pressed out.
- The T-bar key can only be operated when
the ball valve is closed. Make sure it is
closed completely.
- The friction of the o-rings will slow down
the probe when it is retracted.
4-3. Replacing the sensor
Refer to §3-8.
4-4. Drain port connection
The ISC40PR retractable fitting can be
equipped with optional drain port on the
flanged adapter.
The drain port are tapered 1/8” NPT female
for small diameter connectors.
