BoltSafe load cells are specially designed to measure and monitor bolt load in bolted joints very precisely, both during assembly and over time. With this knowledge, safety is enhanced, and joints are more dependable. Better control over the bolted construction is assured! The BoltSafe bolt load cell is placed on the non-driven side of a bolted connection, preferably under a nut. While tightening the bolt, force is being applied, which will result in minor deformation of the stainless steel washer. Changes in electrical resistance caused by these deformations are then constantly measured. We use this data to determine the bolt load very precisely at any given moment.
Besides that, our washers can also be used in temporary construction. In that case, they monitor the load in the construction to make sure that the construction doesn’t collapse. BoltSafe load cells are available in two versions: for continuous bolt load monitoring (the CMS sensor) and for periodic monitoring (the PMS sensor). These are both available in a regular stainless steel version and a stronger version that can withstand 15% more load while keeping the same compact dimensions.
