190501-08-00-00 | Bently Nevada Velomitor CT Velocity Transducer

Introduction to the 190501-08-00-00

When machine vibration threatens uptime, the 190501-08-00-00 from Bently Nevada provides accurate, continuous velocity measurement. This Velomitor CT velocity transducer is engineered for industrial rotating equipment, offering a sensitivity of 3.94 mV/mm/s (100 mV/in/s) with ±5% tolerance. Its robust design helps you detect developing faults early, reducing unplanned downtime and maintenance costs.

Key Features and Technical Specifications

The 190501-08-00-00 is built to perform in demanding environments. Below are the core specifications that define its capability:

• Frequency Response: 3.0 Hz to 900 Hz (180 to 54,000 cpm) ±1.0 dB; 1.5 Hz to 1.0 kHz (90 to 60,000 cpm) ±3.0 dB
• Operating Temperature: -40°C to +85°C (-40°F to +185°F)
• Storage Temperature: -40°C to +100°C (-40°F to +212°F)
• Shock Limit: 5000 g pk, maximum
• Humidity Limit: 100% condensing, non-submerged
• Output Bias Voltage: 10.1 Vdc ± 1.0 Vdc, Pin A referenced to Pin B
• Mounted Resonant Frequency: 9 kHz, minimum (stud mounted, except quick disconnect)
• Case Material: 316L stainless steel
• Weight: <297 g (10.5 oz.), typical

One standout feature is the transverse response of less than 5% of axial sensitivity, ensuring accurate readings even when lateral vibrations are present. This makes the transducer reliable for critical machinery protection.

Applications and Use Cases

The 190501-08-00-00 is ideal for vibration monitoring on pumps, motors, fans, and other rotating equipment. Its wide frequency response and robust construction suit both continuous and intermittent duty cycles. Furthermore, its compact size and any-orientation mounting simplify installation in tight spaces. Consequently, it supports predictive maintenance programs that aim to extend machine life and avoid catastrophic failures.

Installation and Setup

Proper installation is crucial for accurate vibration measurement. The transducer mounts with a plate stud (3/8-in 24 to 1/2-in 20) and requires a mounting torque of 4.5 N-m ± 0.6 N-m (40 in-lbf ± 5 in-lbf). The MIL-C-5015 connection interface ensures a secure, reliable electrical connection. For best results, mount the transducer directly on the machine bearing housing, ensuring a clean, flat surface. Additionally, verify that the mounting angle is appropriate for the measurement axis.

Maintenance and Reliability

Routine inspection of the transducer and its cabling helps maintain measurement integrity. Check for physical damage, loose connections, and signs of corrosion. The 316L stainless steel case provides excellent resistance to harsh environments. As a result, the 190501-08-00-00 offers long service life with minimal maintenance. For any issues, refer to the manufacturer's manual or contact Petro Auto Tech for guidance.

Compatibility and Integration

The 190501-08-00-00 is designed to work with Bently Nevada monitoring systems. Its output bias voltage and dynamic output impedance (<400 Ω typical) ensure compatibility with standard vibration monitoring modules. The maximum cable length of 305 meters (1,000 ft.) allows flexible placement of the transducer relative to the monitoring equipment. Always verify system compatibility with your specific monitor before installation.

Troubleshooting and Common Issues

If you encounter erratic readings, first check the cable and connections for damage. Confirm that the mounting torque is within specification. Also, verify that the transducer is not exposed to temperatures beyond its rated range. For persistent issues, consult the official documentation or contact Petro Auto Tech for technical support.
