Disco was King--and Condition-Based Vibration Monitoring had Barely Begun

Archived online in PDF format, "Machine-Condition Monitoring Using Vibration Analysis--A Case Study from Alma Paper Mill, Quebec, Canada" is an "application note" about an "Abitibi Price" paper mill from European multinational firm Brüel & Kjær Sound and Vibration Measurement.  The report, dating between 1974 (when Abitibi Paper acquired Price Brothers & Co.) and 1979 (when the company name acquired a hyphen as "Abitibi-Price"), offers a glimpse of the origins of vibration monitoring in condition-based maintenance in the paper industry nearly 40 years ago.

If you download the report, be sure to note the photo at the top of page 11.  The caption notes that the firm's "Type 9613 Vibration Monitoring Set, comprising Vibration Meter, Stroboscope and Headphones, provides the tools for a fast, easy check of machine condition...using the ear as an effective frequency analyzer."  One wonders if the bespectacled worker with the notebook and scattered tools, squatting at one end of the massive multi-ton paper press, regarded his task as a "fast, easy check."
