- Page 2 EC Council Directive 89/336/EEC on the approximation of the laws of the member states relating to Electromagnetic Compatibility. Refer to the Declaration of Conformity or contact Kaman Precision Products for details. Power Supply Requirements: The power supply must be CE rated to maintain CE compliance to ESD and power surge requirements.
- Page 3 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.
- Page 4 The switched output can be adjusted using the teach modes. See application information for more details. Switched Output Operation The ThreadChecker’s switched output is a simple on / off switch. The switch is adjusted to trip between a 'threaded' hole and an unthreaded hole during the teach process. Cleaning The ThreadChecker is designed to have limited operation while immersed in liquids.
- Page 5 Before the system is first used it must have the ‘teach’ sequence run. In order to do this you must have a representative threaded and non-threaded hole. The system can be easily calibrated to any new sensor designed for the ThreadChecker as well as for most hole/thread configurations with a simple calibration sequence.
