InteliSENS DGK3000-DC

Triple Axis Diameter Gauge

The InteliSENS® Triple Axis Diameter Gauge, does much more than measure diameter. LED and CCD Technology coupled with our specially designed Optics provide Super Fast diameter and position measurement. This technology has no moving parts, no wear, no drift. The extremely powerful FPGA processor used in the DGK Diameter Gauges enable Super Fast Measurements. 5,000 scans per second per axis in standard configuration which can be increased to 10,000 scans per second per axis. Additional options add functionality to measure, control, alarm and report on product quality.

Gauge Head Add on Hardware

3 Analogue Outputs

3 analogue (+107) outputs can be set to X, Y, Z axis output for 2 and 3 axis gauges. Average diameter, diameter error, ovality and ovality error.

i-BUS x 1

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

i-BUS x 1

The 10k scanning option upgrades the standard gauge to enable a high scan rate that can be used for effective flaw and defect detection, each scan takes just 1ms to obtain and output a new diameter reading.

i-BUS x 1

Maximum, Minimum, Mean, Standard Deviation, Cp, Cpk is collected during a selectable time or length period. The results are updated on the SiDi CD14 Universal Display, PGIS Software and can be transmitted digitally.

i-BUS x 1

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

i-BUS x 1

Fast Fourier Transform (FFT) analyzes the diameter data for periodicity. Providing Amplitutde verses Frequency data and a graphical representation on the SiDi CD14 Universal Display Unit or PCIS Software.

i-BUS x 1

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 a threshold value a Flaw is Detected.
