Efficient process control often depends on the ability to rapidly access data from a large number of sources in the production environment, and with optimum accuracy. That is what Spectrum Brands (St. Louis) sought when it switched to a multiplexer link for verifying tight tolerance weights in both liquid and aerosol filling of product containers at its lawn and garden products division.
Spectrum Brands seized the opportunity when the unit's longtime statistical process control (SPC) software vendor, Hertzler Systems (Goshen, IN), upgraded to Windows-based technology several years ago. To provide the process floor interface to personal computers running Hertzler's Gainseeker SPC software, Spectrum chose the MPX-4S multiplexer from MicroRidge Systems (Sunriver, OR).
