BoltSafe through hole load cells are designed for measuring and monitoring bolt load in bolted constructions, as well during assembly as over time. Knowing this information gives better control over the construction, enhances safety and makes joints more dependable. BoltSafe’s bolt load sensor is placed on the non-driven side of a bolted connection, preferably under a nut. Tightening the bolt results in forces being applied to the through hole load cell. This causes minor deformations of the stainless steel washer. Because of this, changes in the electrical resistance occur, which can be measured using magnetoelastic technology. We use this data to determine the bolt load very precisely at any time.
Our sensors are not only applicable for measuring bolt load, but other loads, forces and weight are also possible. For example, our thru hole load cells are used for Structural Health Monitoring and in temporary constructions. Here they are used to make sure the constructions don’t collapse. BoltSafe through hole load cells are available as a CMS sensor for continuous monitoring and as a PMS sensor for periodic monitoring. Both are available in a standard stainless steel version and in a stronger version that can withstand 15% more load while keeping the same compact dimensions.
