March 12, 2009 - Kaman’s Universal ThreadChecker sensor system checks for thread presence/absence. Designed as a "Go/No Go" tool, ThreadChecker discriminates between a threaded and an unthreaded hole or stud and provides both analog and switched outputs. It offers reliable and repeatable, high-speed thread detection for nearly all thread specifications, including both internal and external threads, and ferrous and non-ferrous materials, including aluminum.ThreadChecker’s universal electronics can be used with any size sensor/probe without factory recalibration.
Kaman offers six sensor models — 2mm, 4mm, 6mm and 10mm diameter probes for internal threads, and 6mm and 12mm diameter probes for external threads — giving ThreadChecker the ability to inspect holes sizes from M3 through M14, and stud sizes M4 through M10.ThreadChecker sensors and the electronics package are designed to be rugged and reliable, meeting IP-67 specifications, and are ideal for machine shop, in-die, or other industrial environments. There is no need to clean and dry the part being checked, as ThreadChecker’s inductive sensors are unaffected by moisture, oils, cleaners, grease, dirt, and grime.The Universal ThreadChecker offers superior performance with both ferrous and nonferrous materials.
Fixed-gain analog output and opto-isolated NPN switching output make this system perfect for set-it-and-forget-it applications including automated assembly and test and inspection.Setup is a simple matter of "teaching" ThreadChecker to recognize a threaded hole or stud vs. an unthreaded one. The user inserts the sensor into a threaded hole or over a threaded stud, and presses the "teach" button. He then inserts the same sensor into an unthreaded hole or over an unthreaded stud, and presses the "teach" button again.
A switched output and system LED will then indicate if a hole or stud is threaded or unthreaded.
