Graduated measuring ranges 0.01 µS/cm – 2,000 mS/cm
Conductivity sensors for optimum process integration: DULCOTEST® sensors meet a wide range of measuring requirements and allow the best solution to any given measuring task to be achieved.
Product description
Online measurement of electrolytic conductivity – with the reliable DULCOTEST® sensors.
After pH, electrolytic conductivity is the second most important measured variable in chemical process analysis. It characterises the ability of an aqueous solution to conduct electrical current. This allows all processes involving salts, acids and bases to be accurately monitored and controlled.
The field of application covers everything from fairly simple water treatment tasks through to complex industrial process waters with stringent requirements in terms of temperature, pressure, contamination tolerance and chemical resistance (e.g. to concentrated sulphuric acid or hydrofluoric acid).

| 2-Electrode Conductivity Sensors |
Conductive conductivity sensors measure the electrolytic conductivity indirectly via the charge transfer between two electrodes immersed in the medium to be measured. The sensor types with cell constants k = 0.01 and k = 0.1 cm-1 are especially suitable for the measurement of the lowest electrolytic conductivities of < 1 µS/cm in pure and ultra-pure kinds of water.
The sensor types with cell constants k=1 cm-1 are used in numerous kinds of water without film-forming ingredients up to 20 mS/cm. The cost-effective sensor range LF(T) is used in clear, chemically uncontaminated water.
The sensor ranges LM(P), CK and CKPt can also be used in chemically contaminated kinds of water and a high temperatures.

| Inductive Conductivity Sensors |
Inductive conductivity sensors consist of a transducer, encapsulated in an inert material. The electrolytic conductivity is measured inductively without direct contact with the medium.
The sensors are used to measure electrolytic conductivity over a wide measuring range, even in heavily contaminated and/or aggressive media and, as such, offer particularly low maintenance operation. The sensors are particularly suitable for measuring high conductivities, as no electrode polarisation occurs. The inductive conductivity sensors are operated using the Compact controller DCCa xx L6 ... The controller includes the testing and calibration kit (Order no. 1026958).

Overview
Online measurement of electrolytic conductivity – with the reliable DULCOTEST® sensors.
After pH, electrolytic conductivity is the second most important measured variable in chemical process analysis. It characterises the ability of an aqueous solution to conduct electrical current. This allows all processes involving salts, acids and bases to be accurately monitored and controlled.
The field of application covers everything from fairly simple water treatment tasks through to complex industrial process waters with stringent requirements in terms of temperature, pressure, contamination tolerance and chemical resistance (e.g. to concentrated sulphuric acid or hydrofluoric acid).

Technical Data
| 2-Electrode Conductivity Sensors |
Conductive conductivity sensors measure the electrolytic conductivity indirectly via the charge transfer between two electrodes immersed in the medium to be measured. The sensor types with cell constants k = 0.01 and k = 0.1 cm-1 are especially suitable for the measurement of the lowest electrolytic conductivities of < 1 µS/cm in pure and ultra-pure kinds of water.
The sensor types with cell constants k=1 cm-1 are used in numerous kinds of water without film-forming ingredients up to 20 mS/cm. The cost-effective sensor range LF(T) is used in clear, chemically uncontaminated water.
The sensor ranges LM(P), CK and CKPt can also be used in chemically contaminated kinds of water and a high temperatures.

| Inductive Conductivity Sensors |
Inductive conductivity sensors consist of a transducer, encapsulated in an inert material. The electrolytic conductivity is measured inductively without direct contact with the medium.
The sensors are used to measure electrolytic conductivity over a wide measuring range, even in heavily contaminated and/or aggressive media and, as such, offer particularly low maintenance operation. The sensors are particularly suitable for measuring high conductivities, as no electrode polarisation occurs. The inductive conductivity sensors are operated using the Compact controller DCCa xx L6 ... The controller includes the testing and calibration kit (Order no. 1026958).

Conductivity Sensor ICT 1-IMA
Cost-effective inductive conductivity sensor, suitable for high electrolytic conductivities above 200 µS/cm. Also suitable for chemically contaminated water and film-forming media. Completely integrated in an immersion pipe
Your benefits
- Measured variable: electrolytic conductivity. The inductive (non-contact) measuring principle permits applications in chemically contaminated types of water and in film-forming media
- There is no need for adhesive or seals as the sensor is fully embedded in PP
- Measurements at high conductivity values of up to 1,000 mS/cm are possible without interfering polarisation by means of the high measuring range dynamics of the inductive measuring principle
- Simple installation in tanks, containers etc. thanks to sensor ready mounted in the immersion tube
| Measuring range | 0.2…1,000 mS/cm |
| Cell constant k | 8.5 cm-1 ±5% |
| Measuring accuracy | < 1% relative to final value of measuring range |
| Temperature compensation | Pt 100 |
| Process chemical temperature | 0…70 °C |
| Max. pressure | 8.0 bar up to 40 °C, 1.0 bar up to 70 °C |
| Material | Sensor and immersion tube: PP Seals: FKM |
| Long immersion pipe | 1 m / 2 m |
| Electrical connection | 7 m fixed cable |
| Enclosure rating | IP 65 |
| Typical applications | Polluted waste water of all kinds, blowdown control in cooling towers, control of electroplating baths, Cleaning in Place (CIP), product monitoring, sea water |
| Resistance to | PP-compatible chemicals, deposit-forming media |
| Long immersion pipe | Immersion sensor complete with 1 m immersion pipe or 2 m immersion pipe. The fitting accessories for the immersion valve IPHa 3-PP can also be used for the immersion sensor. |
