1 Technical Information Indumax P CLS50 Highly resistant, inductive conductivity sensor for standard, hazardous and high-temperature applications Application CLS50 conductivity sensors are especially suitable for application in the chemical industry and process engineering. The six-decade measuring range and the high chemical resistance of the materials in contact with medium (PFA or PEEK) permit the use this sensor in a number of various applications, e.g.: Concentration measurement of acids and bases Quality monitoring of chemical products in tanks and pipes Phase separation of product/product mixtures CLS50 sensors are used with the transmitters Liquiline M CM, Liquisys M CLM/5 or Mycom S CLM5. Your benefits High durability High chemical resistance thanks to PFA coating PEEK version for high temperatures up to 80 C (56 F) Low risk of soiling Dirt-repellent PFA surface Large sensor opening Easy installation Can be installed in T-pieces DN 80 (") with the outgoing diameter reduced to DN 50 (") Total cable length up to 55 m (80 ft) Wide measuring range from μs/cm to 000 ms/cm Integrated, coated Pt 00 temperature sensor, error class A FM, CSA, ATEX approvals TI8C//ae/06.07

2 Function and system design Measuring principle Inductive conductivity measurement A generator () generates an alternating magnetic field in the primary coil () which induces a current in the medium (). The strength of the induced current depends on the conductivity and thus the ion concentration of the medium. The current flow in the medium generates another magnetic field in the secondary coil (). The resulting current induced in the coil is measured by the receiver (5) and processed to determine the conductivity. 5 Inductive conductivity measurement Generator Primary coil Current flow in the medium Secondary coil 5 Receiver Benefits of inductive conductivity measurement No electrodes, therefore no polarization Accurate measurement in media or solutions with a high soiling degree and a tendency to build-up Complete galvanic separation of measurement and medium a00089 Important properties Measuring system Wide measuring range The sensor s measuring range comprises six decades, from μs/cm to 000 ms/cm. Durability The materials in contact with medium (PEEK, PFA) feature a very high chemical resistance. In addition, the PEEK version is suitable for application at high temperatures of up to 80 C (56 F). Low risk of soiling Thanks to its large opening, the sensor is not susceptible to soiling. The PFA version requires even less cleaning thanks to its dirt-repellent surface. A complete measuring system comprises: a CLS50 conductivity sensor with fixed cable a transmitter, e.g. Liquiline M CM Example of a measuring sytem Liquiline M CM transmitter Measuring cable Indumax P CLS50 a Endress+Hauser

4 Installation factor In narrow installation conditions, the ion flow in the medium is affected by the pipe walls. This effect is compensated by the so-called installation factor. The installation factor can be entered in the transmitter or the cell constant can be corrected by multiplication with the installation factor to ensure correct measurement. The value of the installation factor depends on the diameter and the conductivity of the pipe as well as the sensor s distance from the wall. If the distance from the wall is sufficient (a > 0 mm (.8"), from DN 65), it is not necessary to consider the installation factor (f =.00). If the distance from the wall is smaller, the installation factor increases in case of electrically insulating pipes (f > ) and decreases in case of electrically conductive pipes (f < ). The installation factor can be measured using calibration solutions or it can be approximately determined from the following diagram. f a [mm] Dependance of installation factor f on the wall distance a Conductive pipe Insulating pipe a [inch] a00070 Air set Installation of sensors with flange " Caution! To compensate residual coupling in the cable and between the two sensor coils, you must perform a zero calibration in air ("air set") before installing the sensor. For further information, refer to the Operating Instructions of your transmitter. The sensor is suitable for installation in T-pieces DN 80 with the outgoing diameter reduced to DN 50. Tighten the sensor nut (see figures below) with a torque of at least 5 Nm. To avoid leakages, regularly check the tightness of the sensor nut.
