Introduction
Introduction
Thank you for choosing a pHix® Compact
pH / Redox transmitter.
We have done everything possible to make
a pH / Redox transmitter that can fulfill all
your demands.
pHix® Compact is very simple to install and
connect, as electrode, fitting and transmitter
is built together in the same NEMA 6X class
enclosure. By doing so, all error sources
like e.g. bad cable connections and leaking
fittings are eliminated.
As pHix® Compact is equipped with an uni-
on flange in one end and male thread in the
other, the transmitter is very easily mounted
in open tanks as well as pipes without the
usual use of fittings.
You can always contact your representative
or the MJK Service Hotline for advice and
guidance. Also, take a look at www.mjk.com
pHix® is registered trademark of MJK.
MJK Automation is a Xylem Brand!
Safety instructions
1: Read this manual carefully.
2: Be aware of the environment on the in-
stallation site. Wear necessary protective
equipment and follow all current safety
regulations.
3: pHix® Compact can provide a start signal
for dangerous machinery. Always ensure
that connected machinery and other
equipment are effectively being put out
of service (i.e. removal of main fuses,
lock main- and/or security switches in
off position) before commencing setting,
fault finding, service and maintenance
work etc.
Repair
1: Repair must only made by MJK or by a
service representative approved by MJK.
Explosion hazardous areas
pHix® Compact must not be installed in
explosion hazardous areas!

Introduction
EN pHix Compact Manual 1507
Construction
pHix® Compact is a 4-20 mA 2-wire trans-
mitter with power supply and measuring
signal transmitted over the same two wires.
pHix® Compact also has HART® communi-
cation capabilities via the mA wires where
both the primary measuring signal (pH or re-
dox) and the secondary measurement signal
can be read. HART® communication gives
the possibility to configure nearly all para-
meters like measuring ranges, alarm limits,
electrode parameters and also commands
for buffer adjustment.
HART® communication requires that pHix®
Compact is connected to a HART® commu-
nicator or a PLC with HART® interface.
pHix® Compact is delivered as standard for
pH or redox masurement, but can also be
delivered for other types of measurement
and non-standard settings.
An identical marking is found on the pH
transmitter cable:
Product identification
Check that the item(s) delivered corre-
sponds to the ordered item(s). The item
number is printed on a label that is sticked
onto the packing. Shown below is the label
for a delivery including a pHix® Compact
transmitter with pH electrode with zero point
at pH 4,6:

Electrode types
The electrode housing is marked with information about electrode type and measuring range
for the actual electrode:
pH electrode, item no. 160310, 1 - 14 pH, 10 - 80 °C, 0 = 4.6 pH.
pH electrode, item no. 160311, 1 - 14 pH, 10 - 80 °C, 0 = 7.0 pH.
Redox electrode, item no. 160312, 0 - 80 °C.

Mounting
EN pHix Compact Manual 1507
Mounting the electrode
Upon delivery of pHix Compact®, the elec-
trode is not mounted.
pHix Compact® is configured for the
electrode type included in the delivery, and
therefore it must only be used together with
the electrode with which is was delivered.
pHix Compact® shoud be used only with
the electrode type included the delivery.
Contact MJK if other electrode types should
be used.
Replacement of the electrode to another of
same type does not require reconfiguration.
The electrode must not become dry.
Therefore, do not remove the protective
cap before before commissioning of pHix
Compact®.
Gasket, O-ring and plug
It is very important that both gasket and
O-ring and packing surfaces is clean and
smooth and without cracks and scratches
to avoid penetration of liquid in the center
plug connection.
Check that gasket and O-ring are complete and
clean ant that they are placed correctly.
Likewise, the connectors in both transmitter
and electrode should be absolutely clean
and dry. Eventually use a dry cloth.
Check that the connectors are
absolutely clean and dry.

Mounting

1: Smear the O-ring in acid-free grease or
Vaseline.
2: Check that the O-ring is placed correctly
in the recess of the new electrode.
3: Check that the hole for the electrode in
the pHix® Compact is completely dry – if
necessary use a dry cloth.
4: Screw in the new electrode and tighten
by hand.
Do not use tools!
5: Finally, pHix® Compact must be buffer
adjusted prior to commissioning.
See pg. 16.

Mounting
EN pHix Compact Manual 1507
Mounting in open channels and reservoirs
Due to the lifetime of the electrode and
measurement accuracy, the following should
possibly be complied with when mounting
pHix® Compact.
1: pHix® Compact should be mounted on a
location with a good liquid circulation.
2: The electrode tip should be minimum 30
cm below the liquid surface.
3: The electrode tip must not touch the
bottom.
Suspended in the cable
If the liquid is flowing relatively slow and
therefore giving no risk of pHix® Compact
hitting the side of the channel/reservoir,
pHix® Compact may be suspended in the
cable by means of a cable bracket.
Mechanical mounting
General
pHix® Compact is made from Ryton (PPS)
and stainless steel (EN 1.4404 / ASTM
316L), and has because of this a tremende-
ous resistance against chemicals.
pHix® Compact can be used without any
further preparation for measuring in solvents
and strong basic or acid liquids.
Open and closed systems
pHix® Compact is designed for measuring in
both open and closed systems.
Open systems is e.g. gutters, wells, and
reservoirs. Closed systems is e.g. pipe
systems or tanks/vessels.
pHix® Compact is submerged directly into the
liquid and is suspended in the cable by means of a
cable bracket (item no. 560916).
pHix® Compact con-
forms to pressure
class PN 5, and can
therefore be mounted
in closed systems
with a working pres-
sure of max. 5 bar.
pHix® Compact
has class IP 68
enclosure, and
therefore withstands
submersion into open
system to a max.
pressure of
1 bar / 10 mWG.
Max.
10 m !
Max.
5 bar !
