    Description

    Applied Measurements low profile single point platform load cell OBUG is designed for use in weighing scales and a wide selection of low range force measurement applications such as manufacturing, testing, research and development.  It is primarily designed for compression measurements, but it can also measure tension loads, or it can be used bi-directionally.

    The dual cantilever design of the single point platform load cell makes them insensitive to bending moments and also offers extremely high accuracy and stability, while aluminium construction ensures light weight and low cost.

    Applied Measurements can provide customised versions of the single point platform load cell with dimensions and fixings to allow direct retro-fitment in place of obsolete products or to suit specific applications are available on request.

    We selected the OBU series load cells from Applied Measurements because they provide us with the accuracy, long term stability and environmental protection that our weighing systems require – at an excellent price.
