Conductivity sensor LDL100 for interface detection – 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 differentiation between media plays an important role, especially in the food industry. Cleaning agents, rinsing water and food products located in process pipes have different conductivity values and can therefore be easily and reliably detected.

Product validation is possible at all times. Quick and reliable differentiation between the media leads to a reduction in wasted product and rinsing water.

The ability to differentiate between products is an out-of-the-box solution. During installation it is not necessary to make adjustments to the sensor. Enhanced functions are available such as simulation.

Advantages of LDL at a glance:

Much shorter commissioning time

  • No need for additional evaluation electronics
  • Simple wiring using M12

Robust and compact design

  • The fully welded stainless steel housing prevents water ingress

Attractive offer

  • High availability and fast delivery times
  • Flexible adapter concept reduces / simplifies warehousing

Typical cleaning process in the food industry

Target: To differentiate between product and rinsing water by monitoring the conductivity.

Typical cleaning process


  • Target: Exact differentiation between the product and the rinsing water
  • Cleaning process: Water flushes the product out of the pipe
  • The conductivity sensor monitors the interface between media with different conductivity


  • Less spoilt product and rinsing water
  • Process validation

Added value thanks IO-Link

Loss-free signal transmission
Digital transfer of conductivity and temperature values
Plug & Play
Easy to implement using automatic parameters
Transparent process
Internal history memory function
