Specification | Functional Principle Specification Measuring Principle of the Inductive Conductivity Meter An alternating current generates a magnetic field in the primary coil (sender) which induces a current in the circumfluent medium. The current flow in the medium generates another magnetic field in the secondary coil (receiver). The strength of the induced current in the secondary coil depends on the conductivity of the medium. The conductivity of the liquid medium is temperature dependent. To compensate the temperature error, an additional sensor (Pt1000) in the sensor tip is used for monitoring...

Installation Advices | Warnings FOOD Mechanical Connection / Installation ·· The sensor has to be installed in that way that the bobbin case is entirely washed around by media and no bubbles can occure. Installation in a rising pipe is recommended. ·· The inscription “FLOW” on the bottom side of the sensor has to show in flow direction of the medium. ·· Very heavy vibrations can cause measurement errors (e. g. installation very near a pump). ·· Use Negele CLEANadapt system for safe operation of measuring point! ·· Attention: The maximum tightening torque for mounting is 20 Nm! ·· Use a welding...

Parameterization The ILM-4 conductivity sensor is set to operate without requiring special settings. Should the parameters need to be changed, this can be performed using the PC-based MPI-200 programming adapter or the User Interface. The following parameters can be changed directly on-site -in the Justage mode - or using a dry simulation in the office. Display: ■ Language and contrast of operating panel Conductivity measurement: ■ Conductivity 1: Temperature compensation 1 and upper range limit 1 ■ Concentration: Temperature compensation C, medium concentration range and upper range limit C ■...

Operation Creating settings with the User Interface (SUI or LUI) The software structure of the User Interface is similar to that of the PC version. The system is operated using two control buttons to the left and right of the display. These buttons can be used to navigate to the required parameter. The button functions are as follows: Occuring several media with very different conductivity in the application (e. g. CIP cleaning) switching to an adequate measuring range is neccessary for a precise measurement! Detecting the Temperature Coefficient of the Medium Default setting: TC = 2 %/K 2. Submerge...
