OUTLINE
The FCX-CII series transmitter detects the differential pressure or pressure of various
fluids, converts it into a current signal of 4 to 20 mA DC and transmits it.
All the adjustment functions are incorporated in the transmission unit for making
adjustments easily and exactly.
Transmitter settings (such as range and damping time constant, etc.) can be changed from
an HHC (Hand Held Communicator).
Principle
The operating principle of the FCX-CII series transmitter is shown in the block
diagram below.
The input pressure is changed into an electrostatic capacitance in the detecting unit.
The change proportional to the pressure undergoes conditioning and amplification in
the transmission unit, and is then output as a current of 4 to 20mA DC.

6.2 Piping
It is generally recognized that there are appropriate positioning relationship between the
transmitter and main process piping for accurate measurement to avoid harmful gas or liquid
accumulation.
General recognizations are;
1- Mount transmitter below main process piping for liquid or steam measurement.
2- Mount transmitter above main process piping for gas measurement.
The standard style of FCX-CII series transmitter except gauge pressure transmitter correspond to
the piping procedure 1 mentioned above. Change the vent/drain plug to correspond to the piping
procedure 2.
Main valve used for piping should be selected with the maximum pressure of the process taken into account (piping parts such as main valve, etc. should be furnished by
CAUTION user). If the main valve and other parts do not meet the rating, it may result in leakage
of gas or liquid which could lead to a hazard.
6.2.1 Piping of differential pressure transmitters
Check of high/low pressure sides of transmitter
The detecting unit of the differential pressure transmitter bears
symbols H and L which represent high and low pressure sides,
respectively.
Also, vent/drain plugs are provided at the lower process connection,
while impulse pipes are connected at the upper process connections.
L H
Removal of protective cap
The process connection ports of the transmitter and manifold (equalizer) valve are fitted with
protective caps. Before piping, be sure to remove the caps. When removing the caps, carefully protect the threaded portion and sealing face from damage.
Connection of transmitter and impulse pipes
(1) When using the manifold valve, it should be fixed to the transmitter by tightening four oval
flange setbolts (7/16-20UNF), and then the impulse pipe should be connected to the manifold
valve. Tightening torque of 7/16-20UNF mounting bolt should be 30 to 40 N•m (3 to 4
kgf•m).
(2) If a manifold valve is not used, the impulse pipes can directly be screwed into the transmitter. If thread size does not match between the transmitter and impulse pipes, an oval flange
should be used. Tightening torque of 7/16-20UNF mounting bolt in an oval flange should
be 30 to 40 N•m (3 to 4 kgf•m).
Position of process taps (Horizontal main process piping)
The position of the process tap is determined by the relationship between the condition, characteristics and measuring point of the process fluid.
Note the following figures when planning and installing the piping.

Important
(1) Protection is required to prevent dust from entering through the atmospheric
air inlet after installation of the manifold valve.
(2) If process pressure range is narrow (below 10kPa (1000mmH2O)), the following should be considered.
• Pressure variation due to wind around atmospheric air inlet
• Temperature variation near process taps
• Difference in atmospheric pressure between process tap and transmitter
location.
To overcome this, provide atmospheric pressure-side pipe with a proper orifice
and consider accommodating the transmitter and atmospheric air inlet in a box.

Pressure measurement (in case of gas)
Mount the transmitter above the process pipes to
preventing moisture from entering the inside of
transmitter.

Cautions on impulse piping
• For liquid, the impulse pipes should have an upward slope of 1/10 or more between the
process connection and the transmitter to prevent accumulation of gas, etc. in the detecting unit.
• For gas, the impulse pipes should have a downward slope of 1/10 or more between the
process connection and transmitter to prevent accumulation of moisture, etc. in the detecting unit.
• Do not bent the impulse pipes acutely near the pressure outlet port, to prevent gas or drain
from staying in the pipe.
• Take care not to apply an excessive force to the transmitter during connection.
• In order to prevent vibration of the transmitter body and capillary from interfering with
output, the transmitter body should be installed at a vibration-free place and the capillary
should be fixed to a stable support.
• The impulse pipes used should be suitable for the working temperature, pressure, etc.
• When the measuring fluid is likely to freeze in the cover of the measurement chamber,
the cover needs to be warmed up with steam or a heater.

WIRING
Cautions on wiring
(1) Application of a voltage exceeding 60 V DC or 40 V AC (exceeding 32 V DC or 23 V AC
when arrester equipped) between “+” and “–” terminals may result in damage to the transmitter.
(2) Use a shielded cable for the transmission line where possible.
(3) Avoid installation of signal cable and power cable in same conduit or cable tray in order to
prevent increased noise. Also, do not bring the signal cable close to large electrical equipment.
DANGER
In case of an explosionproof arrangement, wiring shall be made in accordance with
the relevant regulations to ensure the explosionproofing.
7.1 Wiring procedure
CAUTION
• Before making wiring work, be sure to turn OFF the main power to prevent
electric shocks.
• Use wiring materials of correct rating to prevent fire accidents.
• After installing the transmitter, firmly close the covers of the transmission unit
and terminal box. If not, rain water enter the transmitter which may result in
trouble or incorrect operation.
Sealing of conduit connection
Use sealing tape, if using metal pipe screw coupling or rubber gasket and fastening gland in the
case of cable (OD ø11) <0.43"> to ensure airtightness of the connection box.
Important
1. If the connection box is located above the transmitter when using a protective tube for the wiring, then moisture may enter the protective tube and have
an adverse effect on the transmitter. So maintaining airtightness of the
connection box is an important practice.
2. The thread of conduit tube should meet the selected size and a seal fixture
should be used.

BUILT-IN ARRESTER
General
An arrester is used to protect a transmitter or receiver from an abnormal voltage such as lightning
surges induced into signal lines. A built-in type arrester is mounted behind the terminal unit. A
nameplate marked “with arrester” is attached to the terminal unit of transmitter with a built-in
arrester.
Installation
The built-in arrester should be used in combination with panel mounting type arrester (type PXC)
for distributor protection.

Maintenance
♦ Check of arrester
• Measure output current from the transmitter check terminals and output current to flow into
transmitter (see figures below).
When current is measured with an ammeter connected to CK+ and CK- terminals, the
internal resistance of the ammeter should be 12Ω or less.
• If the measured two output current are the same, the arrester is normal.
• In case the measured values have a difference of 0.1% (0.016mA) or more, the arrester is
not functioning.
• In the above case, the arrester unit (terminal unit) should be replaced with a new one.
♦ Limitation of insulation resistance and dielectric strength test
An insulation resistance and dielectric strength test should be avoided as a rule, since it
may damage the arrester.
