Industry Applications
This transducer suits critical machinery in power generation, oil and gas, and manufacturing. For example, in a steam turbine train, the 190501-01-99-CN monitors bearing housing vibration to warn of imbalance or misalignment. In a paper mill, it tracks roll and motor vibration to schedule maintenance proactively. The wide frequency response and robust construction make it ideal for continuous duty.
Installation & Setup Guidance
Mount the 190501-01-99-CN using the 3/8-in-24 stud option provided. Apply the recommended mounting torque of 4.5 N·m ± 0.6 N·m (40 in–lbf ± 5 in-lbf) to ensure proper coupling. The transducer can be mounted in any orientation, simplifying installation. Connect the included 32-foot cable (or up to 305 meters of cable part number 02173006) without signal degradation. Verify that Pin A goes positive with respect to Pin B when velocity is from base to top, confirming correct polarity.
Maintenance & Reliability
The sealed 316L stainless steel case and internal electronics isolated from the case provide excellent durability. With no moving parts, the 190501-01-99-CN requires minimal maintenance. Periodically inspect the mounting stud for tightness and check the cable for wear or damage. The unit withstands 100% condensing humidity and up to 5000 g shock, ensuring long service life even in harsh conditions.
Selection Guide & Purchasing Advice
Before purchasing, verify your mounting and connection requirements. This model includes a stud mount and a 32-foot cable, with the CN agency approval option. For other mounting or cable options, consider alternative part numbers. PLC Source PRO offers genuine Bently Nevada parts and can help you confirm compatibility with your monitoring system.
