The ThreadChecker from Kaman Inc
is a new non-contact sensor range
designed to check both internal and
external thread presence for critical
parts manufacture and automated
assembly line applications. Available
in the UK from Ixthus
Instrumentation, the range consists
of a choice of IP67 rated eddy
current probes and an electronics
module with both output and visual
indication for Go-NoGo distance, set
between the probe and the thread.

Four internal probes measure
threaded holes to 14mm diameter;
two external probes are for threaded
shafts to 10mm diameter. Available
to suit most metal materials, probes
operate to 70°C. As Kaman’s eddy
current technology does not require
a high level of part cleanliness,
operation in dirty environments is
said to be guaranteed. Stand T73
