Shinano Kenshi has been manufacturing quality instruments for about 100 years. Following our founding in the silk spinning industry, we branched out into a wide range of fields, including precision motors, information systems, and industrial devices as we created a series of new ideas.

Recent advances in industry require engineers in development departments and manufacturing facilities to quickly verify performance, analyze defects, and improve processes, rendering it extremely difficult to stabilize equipment operation by sole means of the conventional approach of relying on experience and intuition to adjust equipment while observing its operation with the unaided eye.

We experimented with a composite approach to analysis in which we supplemented observations of equipment operation by visualizing signals from vibration, noise, temperature, and other sensors along with equipment control signals, but the technique proved unrealistic because it took an extremely long amount of time to ascertain the causal relationship linking that data with equipment operation.

PLEXLOGGER was created to fulfill the internal need for a tool that makes it easy to record operation and analog signals in a synchronized manner while combining portability with simple setup and efficient operation. The product has since continued to evolve while incorporating a range of feedback from engineers in the field.
