Process industry


Nordkalk Oy extract and process limestone for industry, agriculture and environmental care.

Main selection reasons
  • Long signal cables in area of interference
  • Fast AC switching required

SLI 230CR was chosen for high reliability input signal interfacing when working with the long signal cables that ran besides the conveyor belts.

SLO 24IRA was needed for the processing plant where extremely fast AC switching was needed on a pneumatic grading machine.
