1 Introduction

These operating instructions provide informa‐

tion on the technical data and functions of the

DULCOTEST

®

sensor for inductive conduc‐

tivity, ICT 5 and ICT-IMA.

Sensor type ICT 5 is designed for continuous

flow operation.

Sensor type ICT 5-IMA is integrated in an

immersion tube for immersion in a storage tank

and in an open channel.

The sensor records the electrolytic conductivity

of an aqueous process liquid online. Both types

of sensor work on the basis of an inductive

measuring principle. The sensor is almost

maintenance-free due to the inductive meas‐

uring process. Solid deposits and fatty or oily

films on the surface of the sensor have no

impact on its measuring precision. The sensor

is particularly suitable for measuring high con‐

ductivities of up to 2000 mS/cm. A stand-alone

temperature sensor (Pt1000) with a short

response time records the process tempera‐

ture. The temperature sensor is enclosed within

a protective stainless steel sleeve. Tempera‐

ture correction of the conductivity measurement

in the connected controller is provided for by

the temperature sensor (Pt1000).

Typical applications

The sensor is predominantly designed for appli‐

cations in water treatment and for water moni‐

toring, e.g.:

n Contaminated waste water and process

water

n Air conditioning plants and chillers

n Blowdown control in cooling towers,

n Flushing baths,

n Vehicle washing systems,

n Salt water desalination (feed),

n Swimming pool water control.

You can also use both types of sensor in conta‐

minated water or in aggressive media, which is

chemically inert to PVC/EPDM and/or PP/

EPDM (depending on the design of the sensor).

1.1 Measuring principle

The electrolytic conductivity is measured with

an inductive sensor. The sensor contains a

transmission and receiver coil. Sine alternating

voltage feeds the transmission coil. A sample

flow is induced into the receiver coil depending

on the conductivity of the liquid to be meas‐

ured. The sample flow is proportional to the

conductivity of the medium.

Introduction

1.2 Construction and function of the sensor

The inductive transducer of the two types of sensor ICT 5 and ICT 5-IMA consists of a hermetically

sealed polypropylene (PP) body. A transmission coil and a receiver coil are incorporated in the

transducer. A flow opening in the sensor (sensor eye) permits the measuring medium to flow

through. There is galvanic isolation between the sample medium and the signal output. A stand-

alone temperature sensor (Pt1000) with a short response time records the process temperature. The

temperature sensor is enclosed within a protective stainless steel sleeve.

2.2 User qualification

WARNING!

Danger of injury with inadequately qualified personnel

The operator of the system / equipment is responsible for ensuring that the qualifications are

fulfilled.

If inadequately qualified personnel work on the unit or loiter in the hazard zone of the unit,

this could result in dangers that could cause serious injuries and material damage.

– All work on the unit should therefore only be conducted by qualified personnel.

– Unqualified personnel should be kept away from the hazard zone.

The pertinent accident prevention regulations, as well as all other generally acknowledged

safety regulations, must be adhered to.

Training Definition

Instructed personnel An instructed person is deemed to be a person who has been

instructed and, if required, trained in the tasks assigned to him and pos‐

sible dangers that could result from improper behaviour, as well as

having been instructed in the required protective equipment and protec‐

tive measures.

Trained user A trained user is a person who fulfils the requirements made of an

instructed person and who has also received additional training specific

to the system from the manufacturer or another authorised distribution

partner.

Trained, qualified per‐

sonnel

A trained, qualified employee is deemed to be a person who is able to

assess the tasks assigned to him and recognize possible hazards

based on his training, knowledge and experience, as well as knowledge

of pertinent regulations. A trained, qualified employee must be able to

perform the tasks assigned to him independently with the assistance of

WARNING!

Danger from hazardous substances!

Possible consequence: Fatal or very

serious injuries.

Please ensure when handling haz‐

ardous substances that you have read

the latest safety data sheets provided

by the manufacture of the hazardous

substance. The actions required are

described in the safety data sheet.

Check the safety data sheet regularly

and replace, if necessary, as the

hazard potential of a substance can be

re-evaluated at any time based on new

findings.

The system operator is responsible for

ensuring that these safety data sheets

are available and that they are kept up

to date, as well as for producing an

associated hazard assessment for the

workstations affected.

Installation site

Ensure that there is unimpeded access for sub‐

sequent calibration.

The mounting must be secure and low-vibra‐

tion.

Avoid direct sunlight.

Make sure that the medium flows correctly

through and around the sensor.

Maintain a minimum distance of 20 mm from

the sensor to the tube wall when installing in

pipework.

Minimum compensation will be achieved with

the “Installation factor” parameter if you cannot

adhere to these minimum spacings.

Provide a representative installation site for typ‐

ical conductivity and/or concentration when

immersing in a tank.
