Measurement Technology
LED Light Source and Collimated Optical Lens provides a broad light beam across the measured part surface. The CCD receiver is scanned at 5,000 or 10,000 times per second to measure diameter, position and optionally surface flaws.

Gauge Head Add on Hardware
3 analogue (±10V) outputs can be set to X, Y, Z axis output for 2 and 3 axis gauges. Average diameter, diameter error, ovality and ovality error.
Feedback Control monitors the actual measured diameter compared to a Preset Value and provides a Control Output Signal that can be used to trim the motor output and maintain the product diameter within the Preset Value.
Gauge Head Add on Software
The DGK10k scanning option upgrades the standard gauge to a Super High scan rate, Ideal when used with SMFD Single Measurement Flaw Detection. Each scan takes just 1ms to obtain and output a new diameter reading.
Maximum, Minimum, Mean, Standard Deviation, Cp, Cpk is collected during a selectable time or length period. The results are updated on the SiDi CDi4 Universal Display, PCIS Software and can be transmitted digitally.
Statistical Process Control (SPC) enhances the Feedback Control option. Statistical Process Control, “measures” Process Capability and automatically adjusts the control set point to maximize material savings while maintaining control within upper and lower limits
Fast Fourier Transform (FFT) analyzes the diameter data for periodicity. Providing Amplitude verses Frequency data and a graphical representation on the SiDi CDi4 Universal Display Unit or PCIS Software.
Single Measurement Flaw Detection (SMFD) analyzes each individual measurement and compares it with the running average. If a Single Measurement is greater than the running average and above or below a threshold value a Flaw is Detected.
