CHECKSTAR
ROTARY TORQUE
TRANSDUCERS
The CheckStar Rotary Torque Transducers accurately measure
dynamic torque of power tools, including pulse tools. They provide
a means of verifying torque or torque/angle output of multiple or sin-
gle spindle controlled tools, allowing on-line quality assurance of
your assembly process.
CheckStar transducers have a patented slip ring and brush design
which eliminates “brush bounce” providing confidence in torque
readings. This design carries a Lifetime Warranty and assures no
cost replacement of worn slip rings or brushes.
This series is available in two styles: Industry Standard (IS) and
UTA styles.
● Industry Standard style is manufactured with a military type con-
nector and the torque signal is 2 mv output per volt of excitation.
This style transducer will function with most torque analyzers, read-
outs and data collectors.
● UTA style is manufactured with a “smart chip” in the connector and
will automatically identify itself to the Crane family of torque ana-
lyzers/controllers/readouts and data collectors. When using this style
the user is not required to select span, range or mv per volt parameters.
Available in torque or torque/angle models in sizes from 1/4” hex to
2 1/2” square drive.
