Founded in 1965 by Peter J. Sundt, Metrix traces its roots to seismic measurement technology. Initially focused on geophysical exploration, this technology also found abundant applications for vibration measurements on industrial machines. As a result, machinery condition monitoring emerged as our sole focus and has remained so for 50 years. Metrix pioneered the concept of simple, affordable machinery protection with our mechanical vibration switch offerings, revolutionary 4-20mA vibration transmitters, robust high-temperature velocity sensors, and innovative impact transmitter technology for reciprocating machinery.
