LST SUPERBOLT LOAD SENSING TENSIONER
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.
Features:
- Remote preload monitoring and a live reading of data
- Facilitates more uptime during service
- Precise and repeatable preload reading
- Eliminates the need for modi cations of the bolt
- Seamless to retro t/upgrade — simply replace original nut with the LST
- Robust and reliable, IP67 classed
- Accurate preload veri cation 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 veri cation by
maintenance
TWO VERSIONS CY AND MT:
- CY or MT version
- Standard sizes are M36 – M100
- Standard shaped MJT
- Sensors covered by ring in Delrin material IP67 classed M5 connector in the
nuthouse
LST internal ring (Sensors mounted in the groove) / LST external ring (Sensors are mounted on the outer diameter)
- Enable the use of more readily available standard conguration multi-jackbolt
tensioners (MJTs) (faster turnarounds can be achieved) - External protective ring covers the externally mounted sensors and fully
contains the wiring and M5 connector.
