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.
During shipment, electrolyte in the sensor
could be dislocated. To correct this, place the
sensor upright for 24 hours.
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/
JC) or the small flow fitting K1598AC with
PG13.5 adapter (K1523JB/JD), (see fig 7).
