Operating Manual ILM-4 Application / Intended use • Inductive measurement of specific conductivity and concentration of fluid media in the range of 0…1000 mS / cm • For use in hygienic applications of the food, beverage, and pharmaceutical industries •...
Operating Manual ILM-4 Special features / advantages • The sensor structure is based on a modular device platform which can be tailored to re- quirements and is easy to exchange if faulty • Wear-free, inductive measurement procedure • In contrast to conductive measurement procedures, there are no problems due to elec- trode deterioration or polarization.
Requirements for hygienic installation Conditions for hygienic installation according 3A and EHEDG • The ILM-4 / ILM-4R is designed for CIP/SIP cleaning. The sensor can withstand a maximum of 150 °C / 60 min. • The mounting position must guarantee self-draining properties.

The device should be aligned so that the "FLOW" label on the bottom of the de- vice in the direction of flow. The ILM-4 inductive conductivity meter is set to operate without requiring special adapta- tions. In isolated instances, some parameters may need to be adjusted. The parameterization may be changed using the PC-based MPI-200 programming adapter or the User Interface di- rectly on the sensor.

Operating Manual ILM-4 Settings using the MPI-200 programming adapter The MPI-200 programming adapter is connected to the ILM-4 conductivity meter via the external MPI-200-F adapter. It must be ensured that the ILM-4 conductivity meter is permanently connected to the supply voltage while the parameters are being set.

Operating Manual ILM-4 8.2 Retrofitting the display if a small display (SUI) was already installed First the puck with the mounted display needs to be removed using the puck puller tool (Fig. 4). To do so, detach the wires from the cable terminal. Then insert the five arms of the puck puller in the plastic tabs of the puck (Fig.
Operating Manual ILM-4 Dimensions For all process connections, the conductivity sensor can be ordered with a submersion length of L20 (20 mm) or L50 (50 mm).
