190501-01-00-01 | Bently Nevada Velomitor CT Velocity Transducer

Introduction to the Bently Nevada 190501-01-00-01

When machinery vibration threatens uptime, the 190501-01-00-01 from Bently Nevada provides a dependable solution. This Velomitor CT velocity transducer is engineered for continuous monitoring in demanding industrial environments. Its robust design and precise output help you detect problems early, reducing costly downtime.

With a sensitivity of 3.94 mV/mm/s (±5%), the transducer delivers accurate velocity signals. The frequency response spans 3.0 Hz to 900 Hz (±1.0 dB), covering typical rotating machinery speeds. This makes it suitable for fans, pumps, motors, and other critical assets.

Key Features and Technical Specifications

The 190501-01-00-01 offers several features that enhance reliability and ease of integration:

• 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.
• Output Bias Voltage: 10.1 Vdc ± 1.0 Vdc, Pin A referenced to Pin B.
• Dynamic Output Impedance: <400 Ω typical.
• Broadband Noise: 0.229 mm/s (0.009 in/s) pk.
• Base Strain Sensitivity: 0.43 mm/s/μstrain (0.017 in/s/μstrain).
• Grounding: Internal electronics are isolated from case.
• Maximum Cable Length: 305 metres (1,000 ft.) of cable (part number 02173006) with no signal degradation.

These specifications ensure consistent performance even in challenging conditions. The transducer's temperature sensitivity varies from -8% to +5% over the operating range, maintaining accuracy across -40°C to +85°C.

Applications and Use Cases

The 190501-01-00-01 is ideal for vibration monitoring on rotating equipment. Common applications include:

• Pumps and compressors
• Electric motors and generators
• Fans and blowers
• Gearboxes and turbines

Its rugged construction and intrinsic safety approvals make it suitable for hazardous areas, including Class I, Division 1 and Zone 0/1 environments. This versatility allows you to standardize on one transducer across multiple plant locations.

Installation and Mounting

Proper installation is critical for accurate measurements. The transducer features a 3/8-in 24 stud mounting option, ensuring a secure attachment. The mounting torque should be 4.5 N-m ± 0.6 N-m (40 in-lbf ± 5 in-lbf).

The connection interface uses a MIL-C-5015 connector, providing a reliable and industry-standard link. The transducer can be mounted in any orientation, offering flexibility in tight spaces. Always follow the manufacturer's installation drawing (167536) for hazardous area installations.

Maintenance and Reliability

Regular inspection helps maintain long-term performance. Because the transducer has no moving parts, it requires minimal maintenance. However, you should periodically check the mounting integrity and cable condition.

The 316L stainless steel case resists corrosion, and the internal electronics are isolated from the case, reducing ground loop issues. With a shock limit of 5000 g pk, the transducer withstands harsh mechanical impacts.

Compatibility and Integration

The 190501-01-00-01 is designed to work with Bently Nevada monitoring systems. Its standard velocity output (mV/mm/s) interfaces easily with most vibration monitoring equipment. The MIL-C-5015 connector ensures compatibility with existing cabling infrastructure.

For extended runs, the transducer supports up to 305 meters of cable without signal degradation, simplifying installation in large facilities.

Troubleshooting and Common Issues

If you encounter erratic readings, first verify the mounting torque and connector integrity. Ensure the cable is not damaged and is properly shielded. Check that the output bias voltage is within 10.1 Vdc ± 1.0 Vdc.

If the signal is noisy, confirm that the transducer is not exposed to excessive magnetic fields. The magnetic field susceptibility is <0.0068 mm/s/gauss at 50 gauss, 50-60 Hz, so keep it away from large motors or transformers.
