ThreadChecker Universal

Kaman’s ThreadChecker Measuring System is a noncontact linear proximity measuring

system. This low-cost, easy-to-use system makes precision static and dynamic

measurements of the presence or absence of a thread.

Features Summary / Advantages

• Easy to Use

• Universal Electronics for All Sensor Types and Target Types

• Built in Self Test

• Small size for efficient system integration: less than 4 cubic inches (80cc)

• Flexible packaging and performance.

• Several sensor options.

• Flexible Switched Output Options (window or level comparator / inversion of limit)

available to user

• Low power consumption

ThreadChecker Unit

The ThreadChecker system consists of two subassemblies: the sensor with integrated

cable, and the signal conditioning electronics module with power and output cable. The

ThreadChecker electronics uses a standard 24AWG cable to bring +15 Vdc to +30 Vdc

into the electronics and provide outputs for the analog voltage and switch functions.

Theory of Operation

The ThreadChecker system is an eddy current system. The sensor coil is resonated

and the amount of impedance change in the output is measured by the electronics. The

proximity of the target to the sensor coil will cause the sensor coil to change impedance.

The signal is then processed and filtered to obtain an analog voltage proportional to

the target position or displacement.
