Applications
The Bently Nevada 190501-00-00-00 is ideal for vibration monitoring in:
- Pumps and compressors in oil & gas facilities
- Electric motors and generators in power plants
- Fans and blowers in HVAC and industrial processes
Its high sensitivity and wide frequency response make it suitable for detecting unbalance, misalignment, and bearing wear in rotating machinery, helping to prevent costly downtime.
Installation & Mounting
Mount the 190501-00-00-00 with a stud (mounting hardware option 00 – no stud included) onto a flat, machined surface. Apply a mounting torque of 4.5 N-m ± 0.6 N-m (40 in–lbf ± 5 in-lbf). The transducer can be oriented in any direction. For best results, mount it in direct contact with the bearing housing or machine casing. Use the specified cable (part number 02173006) for connections; the MIL-C-5015 connector provides a secure, weatherproof interface.
Maintenance & Reliability
With no moving parts, the Velomitor CT requires minimal maintenance. Its 316L stainless steel construction resists corrosion and moisture, and its internal electronics are isolated from the case, reducing ground loop issues. The transducer operates in temperatures from -40°C to +85°C and withstands 100% condensing humidity (non-submerged). Regular inspection of the mounting stud and cable integrity is recommended to ensure reliable measurements.
Selection Guide
When selecting a replacement or spare, verify the mounting hardware, connection option, and agency approval requirements for your application. The 190501-00-00-00 comes with no approvals (option 00); if intrinsically safe certification is needed, consider options 01–04.
