A true innovation in the field of preload monitoring, the Superbolt Load-Sensing Tensioner (LST) is among the first of Nord-Lock Group’s Industry 4.0 products.

Equipped with a strain-measuring device, the patented LST analyzes the variation of the tensioner’s circumference in proportion to the variation in bolt preload. Additionally, the LST offers remote monitoring and a live reading of data – all with an accuracy that is better than +/-5%!

• Remote preload monitoring and a live reading of data
• Facilitates more uptime during service
• Precise and repeatable preload reading
• Eliminates the need for modifications of the bolt
• Seamless to retrofit/upgrade — simply replace original nut with the LST
• Robust and reliable, IP67 classed
• Accurate preload verification without adjustment of clamped parts
• No alteration needed of the assembly (including stud or joint design or geometry)
• Removes risk of injuries for operators in hazardous areas
• Eliminates high costs on labor, additional measuring devices and periodic verification by maintenance
