Boltsafe – Load cells

BoltSafe load cells are load sensors specially designed to monitor the actual bolt load in bolted joints. Knowing this information enhances safety, makes assemblies more reliable and enables better control of bolted constructions. The BoltSafe sensor is placed on the non-driven side of a bolted assembly, preferably under a nut. When the bolt is tightened, a force is applied to the load washer, resulting in a slight deformation of the stainless steel washer. The sensor continuously measures the changes in electrical resistance caused by these deformations. This data is used to determine the actual bolt load at any given moment. There are two types of BoltSafe sensors: sensors for continuous monitoring (CMS) and sensors for periodic monitoring (PMS). Both are available in two types of steel: our usual stainless steel and a more resistant version, capable of withstanding 15% more load while retaining the same compact dimensions.
