Bolt Load Sensors

The TEMATE BL is used to measure bolt-load by measuring ultrasonic Time-Of-Flight corresponding to changes in bolt elongation. The TEMATE BL can be customized to meet your unique inspection needs.


  • Non-contact EMAT technique.
  • EMAT sensors do not mechanically load the surface under test allowing a greater precision of measurement of ultrasonic arrival time variation.
  • Capable of working on non-flat bolt heads.
  • Double wave technique (using SH and L wave sensor) permits determining the load without knowing the original length of the bolt.
  • Custom software provides actual load readings (MPa or PSI).
  • Portable and integrated options available (including TEMATE POWERBOX H). Check catalog of standard sensors for portable options.
