Section 2 General information

2.1 General handling instructions

Attention!
The sensor will only work correctly when the tip of the probe is completely
immersed in liquid. Ensure the tip of the probe always remains underwater
even when the water level fluctuates.

2.2 Applications

CAUTION!
Potential danger with contact with chemical/biological substances. Working
with chemical samples, standards and reagents can be dangerous. Make
yourself familiar with the necessary safety procedures and the correct
handling of the chemicals before use and read and follow all relevant safety
data sheets.

The sensor facilitates the straightforward and exact determination of the
conductivity of soiled to heavily soiled aqueous solutions. The system is specially
designed for use in municipal and industrial waste water.

2.3 Basic principles

Typical applications include

• Inlet and / or outlet of a sewage treatment plant

• Surface water if within the measuring range (> 250

Various different possible installations enable the system to be adapted to a very
wide range of conditions.

The electrolytic conductivity is the ability of a liquid to conduct an electrical current
(conductivity is the opposite of resistance). In metals, electrical currents are
passed by the movement of electrons, in liquids by the movement of ions. The
conductivity of a liquid depends on the one hand on the ionic concentration, on
the other hand on the temperature of the liquid.

To obtain the real conductivity of the liquid (in
measured
geometry of the probe and that is called the "cell constant or K" (

To be able to make a comparison between the measurements made at different
temperatures, the measurement must be converted to a reference temperature
(as a rule 25 °C).

The tip of the probe comprises two coils that are completely insulated from the
surrounding medium.

Primary coil
(transmitter):

An AC voltage is applied to the primary coil and produces an
alternating electromagnetic field in the surrounding liquid. This
magnetic field generates an electrical current in the liquid.

Secondary coil
(receiver):

The secondary coil determines the current produced by the
ion movements and calculates the conductivity of the liquid
from the current.

The electrical insulation between liquid and sensor (magnetic coupling) has
advantages compared to the conventional method of using metal electrodes:

• no polarisation, for this reason the measuring range is larger

• high mechanical and chemical resistance

• possibility of taking measurements in soiled liquids

3.3 Electrical safety measures and fire prevention measures

The following safety instructions must be observed during the installation
and repair of cables that carry electrical power:

DANGER!
Sensors and controller are designed for compliance with the U.S. and
Canadian NEC as well as the European low voltage directive. No internal
electrical or electronic parts are allowed to be modified in any way, as this
could render the CE conformity void.

WARNING!
Only qualified experts may perform the tasks described in this section of the
manual, while adhering to all locally valid safety regulations.

• Prior to maintenance or repair of the instrument, isolate it from the power

supply.

• When making electrical connections, all applicable local and national
regulations are to be met.

• The use of earth leakage trips is strongly recommended.

• The instrument must be correctly earthed for correct operation.

8

3.4 Chemical safety measures

CAUTION!
Reference and standard solutions are used for the calibration. Some of
these compounds are toxic or caustic.

Potential danger with contact with chemical/biological substances. Working
with chemical samples, standards and reagents can be dangerous. Make
yourself familiar with the necessary safety procedures and the correct
handling of the chemicals before use and read and follow all relevant safety
data sheets.

Physical contact with a calibration solution and inhalation of vapours from a
calibration solution are to be avoided or limited to an absolute minimum.

3.5 Safety measures related to the flow of sample

The assessment of the possible hazards from the individual sample flows is the
responsibility of the user. Suitable safety measures are to be taken to avoid any
unnecessary contact with a flow of sample of unknown composition in relation to

Section 9 Warranty and liability

HACH LANGE GmbH warrants that the product supplied is free of material and
manufacturing defects and undertakes the obligation to repair or replace any
defective parts at zero cost.

The warranty period for instruments is 24 months. If a service contract is taken out
within 6 months of purchase, the warranty period is extended to 60 months.

With the exclusion of the further claims, the supplier is liable for defects including
the lack of assured properties as follows: all those parts that, within the warranty
period calculated from the day of the transfer of risk, can be demonstrated to have
become unusable or that can only be used with significant limitations due to a
situation present prior to the transfer of risk, in particular due to incorrect design,
poor materials or inadequate finish will be improved or replaced, at the supplier's
discretion. The identification of such defects must be notified to the supplier in
writing without delay, however at the latest 7 days after the identification of the
fault. If the customer fails to notify the supplier, the product is considered
approved despite the defect. Further liability for any direct or indirect damages is
not accepted.

If instrument-specific maintenance and servicing work defined by the supplier is to
be performed within the warranty period by the customer (maintenance) or by the
supplier (servicing) and these requirements are not met, claims for damages due
to the failure to comply with the requirements are rendered void.

Any further claims, in particular claims for consequential damages cannot be
made.

Consumables and damage caused by improper handling, poor installation or
incorrect use are excluded from this clause.

HACH LANGE GmbH process instruments are of proven reliability in many
applications and are therefore often used in automatic control loops to provide the
most economical possible operation of the related process.

To avoid or limit consequential damage, it is therefore recommended to design the
control loop such that a malfunction in an instrument results in an automatic
change over to the backup control system; this is the safest operating state for the
environment and the process.
