ABSOLUTE, DIFFERENTIAL AND GAUGE PRESSURE

TRANSMITTER FOR REMOTE SEAL(S)

DATA SHEET

FKB, FKD and FKM models of FCX-AII V5 series of pressure
transmitters accurately measure a gauge, differential or absolute
pressure and transmit a proportional 4-20 mA output signal.
The transmitters use an unique micro-capacitive silicon
sensor in combination with a state-of-the-art digital signal
processing to provide exceptional performances in
terms of accuracy and stability.

FEATURES

1. High accuracy

The Fuji Electric’s micro-capacitive sillicon sensor provides

in standard ±0.065% accuracy for differential and gauge
transmitter models and ±0.2% accuracy for the absolute

transmitter model, for all elavated or supressed calibration
ranges without additional adjustments.

2. Minimum inventory and design

Electronics unit, local indicators and electronics housing
are interchageable among all FCX-AII transmitters.
Fuji Electric remote seals design are based on a welded
conception that provides a reduced and optimized volume

ange to guarantee a perfect vaccum tightness and high

pressure services.

3.Minimumenvironmentalinuence

The Advanced Floating Cell technology provides a high
immunity against temperature variations and overpressure
commonly found in the process industry and substantially

reduces the overall measurement error.

4. HART/Fuji Electric communication protocols
FCX-AII V5 series of pressure transmitters can communicate

using either the universal HART or the proprietary and faster

Fuji Electric communication protocol.

By the use of Device Description files, HART compatible

devices can communicate with any FCX-AII V5 transmitter.

5.Applicationexibility

Various options are available to address most of the pro-

cess industry applications, including :

- Full range of hazardous area approvals

- Built-in RFI lter and lightning arrester

- Analog or 5 digits local indicator with engineering unit

- Stainless steel electronics housing

- Wide selection of materials

- High temperature, high vacuum seals

6. Programmable output Linearization Function

The output signal can be linearized using up to 14 pair­points.

7.Burnoutcurrentexibility

The burnout current value can be adjusted in the ranges of

[3.2 ; 4.0] and [20.0 ; 22.5] mA and can be compliant with
NAMUR NE43 recommandations.

Burnout and saturation currets :

If the self-diagnostic functions detect a transmitter failure,

the burnout function will drive the output signal to either
“Output Hold”, “Output Overscale” or “Output Underscale”

modes.
When “Output Hold” :
The

output signal is held as the last value just before the failure

happens.

When “Output Overscale” :
The

output signal is set within the range of [20.0 to 22.5] mA

SEAL DIAPHRAGMS

Fuji Electric seal diaphragms are dedicated to accurately

measurelevelanddensityonopenandclosedtanks,ow

and line pressure in pipes in heavy process conditions.
The use of remote seal diaphragms avoids the measuring
cell to be directly in contact with the process conditions.
The various diaphragm architectures and the welded seal
construction provide to the Fuji Electric remote seal dia­phragm offer an excellent reliability in harsh processing
conditions such as high static pressure, temperature or
corrosiveness as weel as viscous, crystallizable or abrasive
process.

S

FEATURES

1- Construction

Connection of the remote seal to the measuring cell diaphragms

can be done either by a rigid (direct) or capillary architectures.

The full welded Fuji Electric design allows a free of gasket path
between the remote seal and the differential, gauge or absolute
measuring cell of the FCX-AII V5 pressure transmitters.

Depending the nature of the process, specic lling uids are

available to ensure the optimal transmission of the process
pressure to the measuring cell.

2- Operating principle

The pressure is applied on the remote seal and transferred by
the lling uid through the capillary path to the measuring cell

of the pressure transmitter.

3- Wide variety of materials selection

Depending the process conditions, wetted or non-wetted parts and

lling uids can be selected thanks to the model code denition.

Wetted parts :

AISI 316L, Tantalum, Hastelloy, Monel, Titanum, Zirconium,

AISI 316L with Gold or PFA coating.
Non wetted parts :
AISI 316L

Filling uids :
Standard silicone, uorinated, alimentary, high temperature,
and vacuum specic oils.
For specic process conditions, please consult Fuji Electric.

4- Diaphragm seal types

According to the mounting and operating conditions different

seal types can be useful :

Flush mounting design from DN40 to DN100.
Seals with extensions (50 to 200 mm).
Flanged, screwed or welded neck adapters

Seals for sanitary applications according DIN, SMS or Tri-

Clamp standards.

For specics seals, please consult Fuji Electric.

FUNCTIONAL SPECIFICATIONS

Remote seal diaphragm assembling :

The remote seal can be assembled on the transmiter either

by a direct (rigid) connection (as for level measurement
at the bottom of a tank) or by capillary (distant measuring

point, high temperature process).
The rigid assembling can be either “long design” (in line)
or “short design” (90°) as shown in the outline dimension
drawings.

Capillarytubespecications:

Standard capillary lengthes :

1.5 / 3 / 6 m (other upon request)

Inside diameter :

1 mm standard
2 mm for vacuum service, high process temperature
applications, short response time requirements

Smallest bending radius of the capillary : 100 mm

Capillary tube shealding possibilities :

Temperature limit :
PVC sleeve :

-10 to 80°C
Stainless steel sheald :

-40 to 350°C

Process connection possibilities :

The remote seal diaphragms can be :

- For ush mounting

- With extension

- With mounting adapters mounting (anged, screwed or

welded neck).
The mounting adapter is dedicated to either adapt the

remote seal to a specic process connection or increase the
sensibilty of the transmitter with special process conditions.

Temperature limits :

Ambiant temperature :

-40 to 85°C for transmitter
Process temperature :

-40 to 150°C for rigid mounting, 0 to 350°C for capillary
design, and high temperature lling uid.

Pressure limits :

Working pressure :

Limited by by the smallest value between the nominal ange

rating of the seal diaphragm and the maximum working
pressure of the transmitter.
Vacuum limit :

Depends on the limit of the measuring cell and the lling uid

of the remote seal. For the differential or gauge pressure
transmitter, the vacuum limit is 20 Torr or 27 mbar abs.

Only the absolute pressure transmitter can be used till

absolute zero (FKM).
For process pressure < 20 Torr, please consult Fuji Electric.

PERFORMANCE SPECIFICATIONS

To evaluate the global performances, both the transmitter and the
remote seal diaphragm performances must be considered under

the reference conditions : standard silicone oil lling, SS 316L

seal diaphragm, 4-20 mA output in linear mode.

Please consult Fuji Electric for special applications indicating

your temperature, pressure and vacuum conditions (vacuum

and temperature can occure together).

Other lling uids can be used for your applications.

The correction of the zero drift can be done at factory level
on the complete system (transmitter and remote seals)
by an additional temperature correction operation..

A thermal isolation or a heating of the capillaries minimises
the ambient temperature effect.
