1.3.2 SAFETY OF THE OPERATIVE ENVIRONMENT

• The panel of the 4222 device is protected against the introduction of liquids. Avoid subject

the equipment to the risk of dripping water, sprays of water or immersion in water and the use

in environments in which such risks may be present. Equipment in which liquids may have

accidentally penetrated must be immediately switched off, cleaned and controlled by authorised

and qualified personnel.

• Once programming has been carried out, we recommend that the transparent panel is closed.

• Protection.

• Use the equipment within the environmental limits of temperature, humidity and pressure

specified. The instrument has been developed to operate in the following environmental

conditions:

− Temperature of the working environment 0°C ÷ +50°C

− Temperature of storage and transportation -25°C ÷ +65°C

− Relative humidity 10% ÷ 95%RH – not condensing

CAUTION

The water treatment plant in which the instrument is introduced must be developed in

accordance with the functional requirements imposed by current legislation.

The apparatus must be inserted perfectly into the plant.

The plant must be kept operative in full compliance with the safety regulations provided.

The parameters indicated on the analyser must comply with current regulations.

Any signals of faults to the device must be positioned in an environment that is constantly

controlled by operative personnel or plant assistants.

Non compliance with even just one of these conditions may lead the “logics” of the device

to operate in a potentially dangerous manner for users of the service.

Therefore, we recommend that service personnel and/or maintenance personnel operate

with the utmost care, pointing out any changes to the safety parameters immediately, in

order to avoid the creation of any potentially dangerous situations.

As the considerations indicated above cannot be controlled by the product in question, the

manufacturer will not be held responsible for any damages that these malfunctions may

cause to people or things.

1.7 INFORMATION ON RECYCLING AND USE OF MATERIALS

CHEMITEC, in accordance with specific European regulations, aims at constant improvement of

development and of production procedures of its equipment with the objective of drastically

reducing the negative impact on the environment caused by parts, components, consumption

materials, packaging and the equipment itself at the end of its life cycle.

Packaging is conceived and produced to allow for its re-use or recovery, including recycling of the

majority of the materials and to reduce the amount of waste or residues to be disposed of, to a very

minimum. In order to assure a correct environmental impact the equipment has been designed with

the smallest circuit possible, with the lowest differentiation possible of materials and components,

with a selection of substances that guarantee utmost recycling and maximum reuse of the parts and

waste disposal free from ecological risks.

The equipment is made in such a way as to guarantee the easy separation or dismantling of the

materials containing contaminants compared with others, in particular during maintenance

operations and the replacement of parts.

CAUTION

The disposal/recycling of packaging, of consumption materials and of the equipment itself

at the end of its life cycle must be carried out in accordance with the norms and regulations

that are currently valid in the country in which the equipment is used.

1.7.1 SPECIAL ATTENTION TO CRITICAL COMPONENTS

2 GENERAL DESCRIPTION

The analyser of this manual is made up of an electronic device plus a technical manual.

The device may be installed on an electrical board or to the wall at a maximum distance of 15

metres from the measuring Probe.

It is powered by the network (85÷265Vac/dc-50/60Hz) by a Switching feeder.

This equipment has been designed to analyse ON-LINE and pilot the dosage pumps for the

treatment of water in different applications:

• Waste water treatment plant

• Treatment and Discharge of Industrial Water

• Fish farm

• Primary Water, Drinking Water

Figure 1 – Wall (a) and panel (b) mounting Conductivity analyzer (4222)

2.1 MEASURING PRINCIPLES

The electrical conductivity measure shows the ion concentration into a solution.

More is the solution acid or even basic salt quantity, higher is the conductivity. The conductivity

measuring unit is Siemens/cm. The measuring scale for water solutions starts with the ultra-pure

water whose conductivity is 0.05 µS/cm (25°C). Conductivity of the natural water, e.g. of the

drinking water, or of the surface waters is of about 100 ... 1000 µS/cm. Some bases, as the

potassium hydroxide, with values being slightly higher than 1000 ms/cm, reach the scale upper

value.

In particular, the conductivity measuring is used in water analysis (drinking water, mineral water,

underground water, distilled water, demineralised water, boiler feed water, waste water), for

galvanic baths controls, purity controls (organics, nutrients), in the thermoelectric units (steam-

condensate cycle control), in the food industries, in sugar factories, cellars, textile industry,

automatic irrigation plants, etc.

The electrical conductivity of a solution is defined as the reciprocal of the opposite resistance by a

cubic centimetre of such a solution, at a certain temperature, i.e. of the resistance being measured

between two 1 cm

2

surface electrodes, 1 cm. away, immersed in the above solution.

Taking the 20°C temperature as a reference, the conductivity changes as per the following formula

where:

C

t

= conductivity to the temperature T

C

20

= conductivity at 20°C

T = solution temperature

α = T coefficient at 20°C in % / °C

The α value is between 1.3 and 3.1%/°C for almost all of the electrodes and is usually 2%/°C in the

diluted solutions. Aiming at comparing the various solutions conductivity values, it is necessary to

bring all the measure back to the 20°C reference temperature using the above said formula (take

note that if the conductivity meter does not include the temperature equalizer, the measure refers to

the solution conductivity at the effective temperature; if the conductivity meter includes the

equalizer, the conductivity shown refers to that of the solution when brought to the selected

reference temperature, nevertheless the solution temperature at the measuring time). The

conductivity measure can be taken using both the electronic instrument and a measuring cell. The

cell includes two ore more electrodes. The base electrical feature of the conducimetric cells is the

“cell factor” (K) depending exclusively on the geometric dimensions of the cell and expressed in cm

(cm

F

[2]

where:

C

s

= solution specific conductivity

C = conductivity reading on the instrument

K = cell constant, in cm

-1

F = cell factor, in cm

For measuring the low conductivity values it is recommended to use high factor cells and vice-

versa. Another important distinction standard relates to the materials of the electrodes, i.e.:

 platinum-plated (Pt spongy surface)

 stainless steel (properly satin and oil free surface)

 graphite

The concentric (or self-shielded) cells are then distinguished from the symmetrical electrodes. The

measure accuracy and stability might be highly reduced by the electrode polarization and

contamination. The polarization effect is due to the electrostatic charges that generates on the

electrode surfaces (even if the ion movement is due to an alternate electric field) and is particularly

detected under concentrate solutions; on the contrary, the contaminations are due to deposits,

encrustations, oil, grease, etc. The two phenomena can be (partially) reduced by using electrodes

made of a material suitable to the solution and by using a proper frequency of the oscillator

powering the cell.

 Main hardware characteristics of the electronic device

The hardware structure of this periphery is based on the adoption of extremely new CPU CMOS

with 8 bits developed specifically for the execution of the so-called “embedded” applications.

The card uses an EEPROM to store the Set-up data and flash memories for storage of the archives

of historical data and LOG files of events.

The Card has 1 RS485 gate (opto-isolated) for local networks used for connections with local

communication devices (configuration computer, terminals and remote controls etc).

The card integrates a Real Time Clock (clock with date) that allows the software to storage figures

in a chronological order.

 The device has been designed to be fitted onto a panel, and is built with an IP66 protection

panel.
