Platform Load Cell

Category: Tags: , , , ,

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.
