  • Description

    The miniature ring load cells of the 8438 series have been specially designed to show-up with small external dimensions. These sensors can be used for a wide range of industrial and laboratory applications due to their small size. The small diameter and height make this miniature ring load cell perfect for installation in structures, in which the measured force is guided directly through the sensor after disconnection.

    Examples of this are force measurements on

    • Bolts
    • Screws
    • Plate and cover fasteners
    • Bearing contact forces
    • Spot welding machines
    • Cutting tools

    The measured tension and compression force must be introduced axially and perpendicularly to the entire surface of the inner and outer bands of the sensor in the opposite direction. Conversion of the acting force into an electrical output signal is performed by strain gauges connected together in a full bridge circuit. To achieve optimal accuracy, the base of the sensor should rest on a smooth level surface, hardened to at least 63 HRC with sufficient dimensions. The base cover welded to the surface has a stabilizing effect on the sensor element. Lateral forces should be avoided anyway as they distort the measured results.

    During installation or operation, ensure that the cable outlet and the sensor cable are not subject to excessively high tensile or bending forces. Strain and bend relief may be necessary for the sensor cable on the machine side.
