Conductivity sensor LDL200 for CIP monitoring – a new approach

  • Reduce inaccuracies associated with a time-based cleaning process
  • Improve process performance with flexible measurement points
  • Compact, high-quality sensor design prevents failures and unplanned downtime


  • Simplify your installation and commissioning processes
  • Loss-free signal transmission of measurement values

The sensors are used in cleaning processes (CIP) in the food industry. They detect the concentration of cleaning agents, check the rinsing water for residues and for product validation.

Precise, fast and reliable measurements during the process help to improve plant availability and optimize cleaning cycles. Reduced amount of cleaning agents, lower energy consumption during rinsing and lower water consumption result in considerable cost savings.

Benefits when using ifm
Simple order process, extremely short delivery times, user-friendly integration into the application – Are you now interested?

Typical cleaning process in the food industry

With one sensor in the inlet and outlet it is possible to measure the following:

  • Concentration of wash fluids in the rinsing water
  • Contamination of the rinsing water
  • Product residues in the return pipe during the cleaning process

Typical cleaning process

With one sensor in the inlet and outlet it is possible to validate the different stages in the cleaning process with process water, caustic and acidic solutions.


  • Using conductivity sensors can reduce the amount of water and chemicals required: Cleaning and rinsing on demand
  • The quality of the cleaning process is reproducible
