Always near you: With a strong sales and service team that looks forward to providing personal support, answering your questions and offering professional training. 

  • Confirmed precision: OIML certificate for C6, Y up to 50,000
  • Maximum capacity: 3 kg ... 75 kg

Developed for Checkweighers

  • Extremely stiff design allows for higher throughput of your checkweigher, due to fast signal response and short filter times
  • Steel is optimal for the food industry and resistant to strong detergents
  • Integrated electronics close to the sensor allows for maximum precision. Active temperature compensation guarantees precise results even in the event of temperature variations.


  • 1000% overload stability: Should it happen - the load cell even withstands cleaning crews stepping on it when working in a hurry
  • Excellent off-center load behavior: Suited for various conveyor sizes up to 600 mm length
  • IP66 up to the connector: Developed for wash-down applications involving the checkweigher being completely covered in foam
  • Connector instead of cable: Fast replacement in case of an emergency


  • FIT7A allows for stand-alone evaluation of light barriers and control of ejectors: No additional PLC is required
  • Tried and tested filter eliminates conveyor drive, roller and conveyor interference
  • Operation via free PanelX software: Saves valuable development time and supports you in optimizing your checkweigher
