CALIBRATION CHAIN

DYNNAMIC ACCURACY VERIFICATION OF BELT SCALE AND WEIGH BELT FEEDER

  • 2 available pitches depending on weighbridge length.
  • Double chains for belt width > 1 meter.

    General information

    Calibration chains (CLM85 and CLM90) are essential accessories to any user of conveyor belt scales or weighbeltfeeders. It’s often very difficult to check the dynamic accuracy of a beltscale or a weighbeltfeeder installed in a continuous production line if there is no material deviation possibility for a drop test.

    Each CLM calibration chain consists of 1 hanging shaft with hook and several roller segments. The segment pitch is selected according to the weighbridge length.
    - For a short weighbridge, choose a segment with 100mm pitch.
    - For a long weighbridge, choose a segment with 200 mm pitch. The required total calibration chain length is defined according to the weighbridge length.

    2 - Chain types

    There are 3 possible material qualities: steel, cast iron or stainless steel. The segment pitch is either 200 mm or 100 mm A range of weight per meter is available as standard.

    Type CLM85
    Materials : Cast iron or stainless steel.
    Standard lengths: 4.2, 5.2, 6.2 and 7.2m (others on request)
    Pitch : 200 mm

    Weight per meter (kg/m) 30 40 50 65 80
    Width 185 200 215 230 245

    (Other weights per meter on request)

    Type CLM90
    Standard lengths: 2.6, 3.2, 4.2, 5.2m (others on request)
    Pitch : 100 mm

    Weight per meter (kg/m) 30 40 50 65 80
    Width 185 200 215 230 245 

    (Other weights per meter on request)

    Determination of the chain weight per meter of chain

    Depending on the nominal belt load (kg/m) on the beltscale or weighbelt feeder, the weight per meter of the chain will represent :

        • - 80% - 110% of the nominal belt load for weighbelt feeders.
        • - 50% - 100% of the nominal belt load for beltscales

    plan-L-W-S

    L= Lenght
    W= Width
    P= Pitch

    Double chain

    For belt widths larger than 1 meter, choose a double chain.

    Calibration certificate

    On request at the time of order, HASLER Group will provide a calibration chain certificate issued by the Weights & Measure Authority.
