ASI DATAMYTE’s LightStarTM
system raises the quality bar by error-proofing residual torque, power
tool optimization, hand assembly and rework operations. It eliminates
the crippling downtime associated with reacting to false out-of-spec
readings and the big costs associated with missing true
defect conditions.

LightStarTM torque and angle wrenches reduce variability in torque measurement. The
LightStarTM system gives you the most reliable way to eliminate false readings and increase accuracy of residual torque measurement.
The time between fastener motion and operator response is a key driver of variability when measuring peak torque This is why assessing residual torque by measuring peak torque is subject to operator error that induces false high and false low readings, as well as much higher variability than measured installed torque.
A solid‐state gyro in the wrench captures torque only when the fastener actually turns. The data collector’s instrumentation differentiates between windup – the flexing of the work piece, drive, socket and extension – and actual fastener motion.
This system consists of:
> LightStarTM Torque Wrenches with angle measurement option
> Model 600 Data Collector with torque option
> TranSend II utility software
> Setup Editor and Reporting and Analysis Software
Rotary TransducersIn addition to LightStar
TM
wrenches, rotary transducers can be used with the 600 to measure torque
at installation from ramp-type or pulse-type power torque tools.
Manufactured
for ASI DATAMYTE by Crane Electronics, these industry standard
transducers fit in-line between the assembly tool and the fastener,
measuring the actual torque applied and angular rotation of the fastener
under production conditions.
