Modular inductive conductivity measurement of liquid media up to 999 mS/cm, with IO-Link

Now with 5 years warranty! More details: click here

  • Extremely short response time of 1.2s for highest efficiency
  • Flex-Hybrid: Digital IO-Link and analog 4…20 mA in parallel
  • Accurate phase separation of different media means less resource losses and cost optimization
  • Maximum use of the cleaning agents in CIP processes thanks to correct re-guidance into the respective storage tanks
  • Minimum cleaning time and water consumption: active switch-over after reaching the desired value by inline analysis and not by passive, pre-set time control
  • Precise concentration of the cleaning agents
  • Modular design: configurable from the low-cost basic version to the high-end model

BenefitsBenefits in production and CIP / SIP processes: ILM-4 with IO-Link and 4...20 mA enables an active, automated and temperature compensated phase separation. This appliesboth to different media in production processes and to the CIP / SIP return flow of acid / caustic/ water. These media can be drained or returned to the storagetanks in the highest possible grade by means of precise inline conductivity measurement. The multiple use of the cleaning media ensures in addition maximum cost efficiency and environmental protection.Benefits incleaning agentscontrolFor an optimal and reproducible cleaning result, each cleaning agent must be concentratedto the specified value by re-dosing with concentrate and fresh water. This is ensured by the highly precise measurement of conductivity with the ILM-4. Advantages of the ILM-4 conductivity sensor·Extremely short response time (1.2 s)for maximum efficiency·Ready for industry 4.0: digital IO-Linkinterface and analog 4...20 mA data transmission in parallel·Precise phase separationof different media means less product lossand cost minimization·Optimum multiple use of the cleaning chemicals due to correct return to the respective tanks· Minimization of cleaning time and water consumption:inline conductivity analysis for active switching after reaching the desired value and not after a passive, fixed time·Precise concentration controlof the cleaning agents· Reliable product monitoring / quality assurance· Very favourable price-performance ratio
