190501-10-00-CN | Bently Nevada Velomitor CT Velocity Transducer

Product Overview

The Bently Nevada 190501-10-00-CN is a Velomitor CT velocity transducer engineered for precise vibration measurement in industrial machinery. This model features a plate stud mounting option (M6x1 to M6x1 with a 3/8-24 adapter) and a MIL-C-5015 connection interface, ensuring secure installation and reliable signal transmission. With a sensitivity of 3.94 mV/mm/s (100 mV/in/s) ±5%, it delivers accurate velocity data essential for condition monitoring and predictive maintenance programs.

Built for demanding environments, the 190501-10-00-CN operates across a wide temperature range of -40°C to +85°C (-40°F to +185°F) and withstands shock up to 5000 g pk. Its 316L stainless steel case and connector provide excellent corrosion resistance, making it suitable for harsh industrial settings. The transducer's internal electronics are isolated from the case, reducing ground loop issues and enhancing signal integrity.

The 190501-10-00-CN also offers intrinsic safety approvals (Ex ia IIC T4 and AEx ia IIC T4) for hazardous locations, with installation per drawing 167536. This makes it a versatile choice for industries requiring robust vibration monitoring in explosive atmospheres.

Applications & Use Cases

This velocity transducer is ideal for monitoring rotating machinery such as pumps, fans, compressors, and turbines. Its wide frequency response and high shock tolerance make it suitable for both low-speed and high-speed equipment. In petrochemical plants, the intrinsic safety certification ensures safe operation in classified areas. Additionally, the transducer's any-orientation mounting simplifies installation in tight spaces, reducing downtime during setup.

Installation & Setup

For optimal performance, mount the transducer on a flat, clean surface using the provided plate stud (M6x1 to M6x1 with 3/8-24 adapter). Apply the recommended mounting torque of 4.5 N-m ± 0.6 N-m (40 in-lbf ± 5 in-lbf). Ensure the cable length does not exceed 305 meters to avoid signal degradation. The MIL-C-5015 connection interface provides a secure, weather-resistant connection. Always follow the manufacturer's installation drawing (167536) for hazardous area installations.

Maintenance & Reliability

Routine inspection of the transducer and its mounting is recommended to ensure consistent performance. Check for any signs of physical damage or corrosion, especially in harsh environments. The 316L stainless steel construction offers excellent resistance to corrosive media, extending service life. Periodically verify the output bias voltage (10.1 Vdc ± 1.0 Vdc) to confirm proper operation. For any maintenance concerns, consult the official Bently Nevada documentation or contact Petro Auto Tech for guidance.

Compatibility & Integration

The 190501-10-00-CN is compatible with Bently Nevada monitoring systems and can be integrated into existing vibration monitoring networks. Its standard MIL-C-5015 connector ensures easy replacement of older transducers. The transducer's grounding isolation minimizes interference, making it suitable for use with various data acquisition systems. For specific compatibility details, refer to the product datasheet or consult with Petro Auto Tech.

Troubleshooting & Common Issues

If the output signal is absent or erratic, check the cable connections and ensure the transducer is properly mounted. Verify that the mounting torque is within the specified range to avoid resonance issues. If the bias voltage deviates from 10.1 Vdc ± 1.0 Vdc, the transducer may require replacement. In hazardous areas, always follow the installation drawing to maintain intrinsic safety. For persistent issues, contact Petro Auto Tech for technical support.
