Anderson Negele’s ILM 4 inductive conductivity monitors provide fast, accurate, and hygienic inline conductivity measurement for phase separation, CIP/SIP control, and product verification in food, beverage, dairy, pharmaceutical, and other sanitary processing environments.

Using a wear free inductive measuring principle, the ILM 4 delivers temperature compensated conductivity values in real time, with a response time as fast as 1.2 seconds, ensuring precise separation of cleaning agents, product recovery, and optimized water and chemical usage. The ILM 4 measures conductivity from 0 to 1,000 mS/cm, supporting a wide range of process media—from product differentiation to aggressive cleaning solutions.

1.) Fast, Accurate, Real‑Time Measurement

• Ultra‑fast response time of 1.2 s enables tight control of phase transitions and reduced product loss. 
• High reproducibility of ≤0.2% ensures stable and repeatable measurements. 
• Integrated temperature compensation ensures accurate readings even with rapid media changes.

2.) Hygienic, Wear‑Free Inductive Technology

• Inductive measurement eliminates electrode deterioration and polarization issues present in conductive sensors. 
• Designed for 3‑A and EHEDG‑compliant hygienic environments (based on process connections such as CLEANadapt or Tri‑Clamp). 
• CIP/SIP capable up to 150°C for 60 minutes, supporting stringent cleaning demands. 

3) Flex‑Hybrid Output for Modern Automation

• Simultaneous IO‑Link and 4–20 mA outputs enable digital diagnostics, predictive maintenance, and compatibility with legacy PLC systems. 
• Adjustable analog outputs for conductivity, temperature, or concentration provide process flexibility. 

4.) Cost Savings Through Process Optimization

• Accurate phase separation prevents mixing of product with cleaning agents or water, reducing waste and increasing yield.
• Inline measurements eliminate manual sampling and shorten cleaning time by enabling real‑time switching based on actual conductivity values rather than fixed timers.
