Load Monitor with Statistical Process Control
Process Protection and On-line Quality Control
The SPC Loadgard continuously calculates and records the mean and range for each part produced. These x Bar and sigma charts will display the extent of common cause variation which translates into a statistical measurement of part quality.
- Four channel load monitor and on-line SPC controller in one box
- Full color, menu driven touch screen display performs SPC data collection based on job recipe
- RISC processor with pre-installed Windows CE operating system
- Ethernet and RS-232 communication ports
Control Charts you need to keep your process on course!
To help reduce die set-up time, the SPC Loadgard will store key operating parameters including the statistically sampled target load values for each job. This feature provides assurance that all jobs are set within their process capability window.
A detailed history of each alarm occurrence will help identify and track the causes for process variation. The downtime events are charted in decreasing order of frequency in a Pareto chart format.
Histogram charting shows the comparative frequency of the load measurements. The size of the histogram will indicate that an off tolerance condition exists at a specific point in the production run.
