SureBolt's Whole Echo
patented technology greatly increases reliability by using the whole echo
instead of just one point. All other bolt gages use just "One
Point" (one zero crossing), that leaves you susceptible to peak
jumping (20% or more error). Surebolt is a more reliable bolt gage due to
a new patented technology. See comparison table.
Bolt gages have been around for over 20
years. Their "Peak Jumping"
problems and challenging learning curves, have kept them from being widely used. When your bolted joint
fails or flange leaks, then you find out your one-point bolt gage may have
Example, with a lot of training and laboratory testing, NASA has used bolt
gages for years. NASA physically takes Polaroid pictures of the echoes
before and after tensioning. Then they use their trained human
experience to determine if the echo has distorted
"too-much". Even after all
this, they have to throw away approximately one third of the ET
measurements because they are not reliable. When NASA used the
SureBolt prototype, no measurements had to be thrown away.
SureBolt gives you a 13.3" TFT, portable PC
(Panasonic Toughbook Model 72). The ultrasonic pulser and digitizer are built into the CD ROM
and PCMCIA slots. Click here to see

to see how an ultrasonic bolt gage can measure tension. SureBolt has been used
on special high strength titanium bolts to standard "off the shelf"
