Hamilton Conducell 4US sensors are quality products manufactured with the latest technology.
These instructions should be read, understood and followed by all staff using the device.
Hamilton can assume no responsibility for damage and operational disruptions arising from
failure to observe these instructions.
1 Liability
The Liability of Hamilton Bonaduz AG is detailed in the document “General Terms and Conditions
of Sale and Delivery (GTS)”, chapter 12.
Hamilton is expressly not liable for direct or indirect losses arising from use of the sensors. It
must in particular be insured in this conjunction that malfunctions can occur on account of the
inherently limited useful life of sensors contingent upon their relevant applications. The user is
responsible for the calibration, maintenance and regular replacement of the sensors. In the case
of critical sensor applications, Hamilton recommends using back-up measuring points in order
to avoid consequential damages. The user is responsible for taking suitable precautions in the
event of a sensor failure.
INTENDED USE • SAFETY • INITIAL OPERATION
2 Intended use
With the Conducell 4US line, Hamilton has developed a family of in-line conductivity sensors
which perform under demanding conditions in biotechnology and the general chemical industry.
During development, special attention was paid to an optimum sanitary design. All materials in
contact with the solution are FDA approved.
The sensors are based on the 4-electrode principle which excludes polarization phenomena
normally observed with 2-electrode sensors. The engineered design guarantees an excellent
linearity over a conductivity range of more than 6 decades.
3 Safety
This sensor is to be used only as intended and is to be kept in a condition that ensures complete safety. The specifications given in the section “Technical Data” as regards temperature,
pressure etc. may under no circumstances be exceeded.
Inappropriate use or misuse can be dangerous.
Assembly and maintenance may only be done by trained personnel.
During assembly, ensure that the positioning is correct and that the O-ring is undamaged.
O-rings are consumable items and must be replaced regularly – at least once a year.
The built-in temperature sensor should only be used for compensation of conductivity, not for
controlling the process temperature.
Conducell 4US sensors are used to determine electrolyte conductivity in solutions. If these
sensors are used in potentially explosive atmospheres, see the section “Instructions for use in
potentially explosive atmospheres”.
4 Initial operation
This Conducell 4US sensor has been carefully tested and is ready for use. During unpacking,
please check for any mechanical defects. In case of a complaint please return the Conducell
4US in its original packing to your Hamilton representative and describe the problem.

ASSEMBLY
6 Assembly
Please check if the process connection is sufficiently clean. Then fit the Conducell 4US.
Please follow the instructions mentioned below.
Examples:
ATTENTION! The cell
constant and the linearity
of the sensor can vary
with the fitting situation.
A symmetrical setup is
recommended. Leave an
open space of 60 mm
minimum diameter.
Partitions made of
non-conductive material
Ø 60mm
min
should preferably be
used.
ATTENTION! A
symmetrical setup is
recommended in order to
ensure a high degree of
linearity. To achieve high
precision the cell constant should be calibrated
in the final setup. Make
sure that all 4 electrodes
are completely and
continuously immersed in
the measuring sample.

CALIBRATION
8 Calibration
There are two possibilities for calibration:
1) Calibration while sensor is disassembled from process:
• First, rinse the sensor thoroughly with deionized water.
• Use a beaker or container that has an (internal) diameter of at least 30 mm. (Conducell
4US fits perfectly into the Hamilton Conductivity Standards, and can be calibrated directly
in the bottle.)
• Use a solution of known conductivity. Check the temperature table of the conductivity
standard.
• Immerse the lower part of the sensor in the standard. Make sure that the 4 electrodes are
completely immersed. The sensor should be placed in the center of the beaker.
• Leave the sensor for at least 5 minutes for equilibration, before initiating the calibration on the
instrument.
For precise determination of the cell constant, it is recommended that you use an assembly
situation similar or equal to the situation in the process. The cell constant may vary with the
assembly situation.
2) Calibration in the process:
• Insert the sensor in the process.
• Leave conductivity and temperature at least 15 min. for equilibration.
• Take a process sample and perform an external measurement with a reference conductivity
system. The best approach is to perform the measurement at a temperature equal to that
of the process. If this is not possible, you need to know the temperature coefficient of your
sample (similar to temperature table on Hamilton Conductivity Standards bottle).
• Manually adjust the cell constant to read the same conductivity value on the process
instrument.
• You may switch off the temperature compensation of the process and the laboratory instruments to prevent any errors.
CLEANING • DISPOSAL • TECHNICAL DATA
9 Cleaning
Conducell 4US can be cleaned with standard cleaning agents. Never use scouring agents
which contain hard particles. Please check the O-rings from time to time. When mounting the
new O-ring take care not to damage the O-ring nut or the O-ring itself. Otherwise the tightness
of seal can no longer be guaranteed.
10 Disposal
The design of Hamilton sensors minimizes environmental impact. According to the
EU directive 2002/96/EC the Hamilton sensors should be disposed as waste of
electrical and electronic equipment, and not in municipal waste, or it can be sent
back to Hamilton for disposal.

1) Uncertainty of ± 5 % arise when using only ONE single cell constant for the full range. ± 0.5% accuracy can be
achieved when calibration is performed in a conductivity range close to that of the sample. Remember also that
linearity is strongly influenced by the transmit ter used.
2) Individual cell constant measured with Hamilton standard procedure printed on the label. The cell constant is
influenced by the assembly situation.

12 Instructions for use in potentially
explosive atmospheres
ATEX / IECEx marking:
Gas: CE 0035 II 1/2 G Ex ia IIB T4/T5/T6 Ga/Gb
Dust: CE 0035 II 1/2 D Ex ia IIIC T x °C Da/Db
Manufacturer: Hamilton Bonaduz AG, 7402 Bonaduz, Switzerland
EC type examination report: TÜV 03 ATEX 7005 X
IECEx certificate of conformity: IECEx TUR 14.0001 X
EC type examination report and IECEx certificate of conformity can be downloaded from
www.hamiltoncompany.com.
CONNECTION TO TRANSMITTER
The conditions described in the ATEX / IECEx certificate must be respected.
ATTENTION! In case a gas atmosphere and a dust atmosphere are or could
be present at the same time, the risk of explosion must be examined carefully
and special precautions may be necessary.
Assembly
1) The operator of equipment in potentially explosive atmospheres is responsible for ensuring
that all components of the system are certified for that area classification and are compatible
with each other.
2) In gas atmospheres, the Ex approval is not dependent on any conditions regarding mounting of the sensor. In dust atmospheres, however, special restrictions may apply when using
armatures made of plastic material.
3) O-rings having a sealing function between Ex-zone 0 and 1 or Ex-zone 20 and 21, respectively,
must be replaced at each dismantling of the sensor.
4) Sensors, transmitter and equipment required are to be set up within one balanced potential
system.
5) When the sensor is assembled, the ATEX / IECEx sticker is to be attached to the cable in an
easily visible place, as near as possible to the sensor itself. This sticker is to indicate that an
ATEX / IECEx approved sensor is in use. The sticker should not be removed at any time.
13 Connection to transmitter
Conducell 4US is suitable for connection to an intrinsically safe electrical circuit with protection
level ia. The operator of the equipment must ensure that the allowable electrical values for the
sensor all exceed those for the transmitter. None of the values cited for electrical power, voltage
and current may be exceeded in sum (measurement and temperature circuit together). Electric
values for Conducell 4US are as follows:
U = 24 V; I = 173 mA; P: Function of process temperature. The maximum allowable electric
power P of the transmitter (measurement and temperature circuit together) depends on the
desired process temperature.
