Products Description
The Bently Nevada 330525-10 Velomitor XA is a heavy-duty piezo-velocity vibration sensor for harsh industrial environments. Part of the Velomitor XA series, it adopts a robust 316L stainless steel enclosure with weatherproof connectors and cables, mountable directly on machinery without extra protective housing.
It delivers precise housing vibration measurement for rotating equipment including motors, pumps, compressors and turbines. It detects faults such as imbalance, misalignment and bearing wear, supplying critical data for predictive maintenance to cut unplanned downtime.
Resistant to moisture, dust and corrosion, the sensor meets IP65 / NEMA 4X standards when paired with matching extension cables, ideal for outdoor and tough process sites. Stable performance and simple installation support long-term machinery protection and continuous vibration monitoring.
