Industry Applications
The 190501-13-00-CN is ideal for vibration monitoring in industries such as petrochemical, power generation, and manufacturing. In a refinery, for example, it can be mounted on critical pumps to detect early bearing wear, enabling predictive maintenance and preventing unplanned downtime. In a power plant, it monitors turbine vibration to ensure safe operation within limits.
With its rugged construction and wide operating temperature range, this transducer performs reliably in extreme conditions, from arctic climates to tropical facilities.
Installation & Setup
Proper installation is crucial for accurate measurements. The 190501-13-00-CN requires a flat, clean mounting surface. For stud mounting (excluding quick-disconnect), the recommended torque is 4.5 N-m ± 0.6 N-m (40 in-lbf ± 5 in-lbf). Ensure the transducer is oriented correctly; any orientation is acceptable, but maintain a consistent direction for comparative readings.
For wiring, connect Pin A and Pin B per the polarity specification. The maximum cable length is 305 meters (1,000 ft.) with approved cable part number 02173006, ensuring signal integrity. Always follow the installation drawing 167536 for intrinsically safe configurations.
Maintenance & Reliability
This velocity transducer requires minimal maintenance due to its sealed 316L stainless steel construction. However, periodic inspection of the mounting stud and connector is recommended to ensure tightness and cleanliness. Check the cable for abrasion or damage, especially in high-vibration areas. The internal electronics are isolated from the case, reducing the risk of ground loops and electrical interference.
With a shock limit of 5000 g pk, the 190501-13-00-CN withstands harsh handling and operational impacts, contributing to long service life and reduced replacement costs.
Selection Guide & Purchasing Advice
When ordering the Bently Nevada 190501-13-00-CN, verify the mounting hardware option (13 = quick disconnect stud) and connection option (00 = MIL-C-5015). Ensure the agency approval option (CN) meets your regional requirements. For assistance with compatibility or to place an order, PLC Source PRO offers genuine parts and expert support.
