Long-reach monitoring for remote control rooms or widely spread machinery without field junction boxes.

Simultaneous capture of slow thermal shifts and high-frequency vibration with micron-level accuracy.

Robust against shock, vibration, moisture, and debris; suited for damp or particulate-laden environments.

Intrinsically safe approvals when paired with certified conditioners, enabling direct mount in classified areas.

Maintains stable sensitivity across full operating range without external recalibration

Probe mounted on gearbox housing, 100 m cable to sheltered VM600 rack; early detection of shaft eccentricity and gear-mesh sidebands prevents costly shutdowns.

Submerged or buried pumps feed 100 m back to dry-area conditioners; continuous eccentricity and vibration monitoring extends seal and bearing service life.

Stainless-steel probe resists salt spray; long cable spans deck height to control room, integrating with VM600 protection cards for journal-bearing eccentricity trips.
