190501-02-00-00 | Bently Nevada Velomitor CT Velocity Transducer

Why Choose the Bently Nevada 190501-02-00-00?

When machinery vibration threatens uptime, the 190501-02-00-00 from Bently Nevada provides the precise data you need. This Velomitor CT velocity transducer is engineered for continuous monitoring in demanding industrial environments. With a sensitivity of 3.94 mV/mm/s (100 mV/in/s) ±5%, it captures accurate velocity signals essential for predictive maintenance.

Manufactured in the U.S.A., this transducer is built to deliver long-term reliability. Its 316L stainless steel case withstands harsh conditions, while the internal electronics are isolated from the case to minimize interference. The result is a dependable sensor that helps you avoid unplanned downtime.

• Temperature Sensitivity: -8% to +5% typical over the operating temperature range
• Transverse Response: Less than 5% of axial sensitivity
• Amplitude Linearity: ±2% to 63.5 mm/s pk (2.5 in/s pk)
• Mounted Resonant Frequency: 9 kHz minimum (stud mounted, except quick disconnect)
• 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)

These specs ensure accurate and repeatable measurements, even in challenging environments. The transducer operates from -40°C to +85°C (-40°F to +185°F) and can be stored from -40°C to +100°C (-40°F to +212°F). It withstands shock up to 5000 g pk and operates in 100% condensing humidity (non-submerged).

Applications and Use Cases

In rotating machinery monitoring, the 190501-02-00-00 excels at detecting vibration anomalies. It is ideal for turbines, compressors, pumps, and fans where early fault detection prevents costly failures. Furthermore, its wide frequency response captures both low-speed and high-speed machine dynamics, making it versatile across various asset types.

For example, in a petrochemical plant, this transducer can monitor a critical pump's bearing health. Consequently, maintenance teams receive real-time data to schedule repairs before catastrophic breakdowns occur. Therefore, the 190501-02-00-00 supports proactive maintenance strategies that reduce downtime and extend equipment life.

Installation and Setup

Proper installation is crucial for accurate readings. The 190501-02-00-00 features a stud mounting option (3/8-in 24 to 1/2-in 20) and a MIL-C-5015 connection interface. Mounting torque should be 4.5 N-m ± 0.6 N-m (40 in-lbf ± 5 in-lbf). The transducer can be mounted in any orientation, simplifying installation in tight spaces.

Ensure the mounting surface is clean and flat for optimal coupling. Also, verify that the cable length does not exceed 305 metres to avoid signal degradation. Finally, confirm that the output bias voltage is within specification (10.1 Vdc ± 1.0 Vdc) before commissioning.

Maintenance and Reliability

Routine inspection is essential to maintain long-term performance. Periodically check the mounting integrity and cable condition. Since the case is 316L stainless steel, it resists corrosion, but environmental factors like vibration and temperature extremes can still affect performance. Therefore, schedule regular calibration checks to ensure accuracy.

The transducer's internal electronics are isolated from the case, reducing ground loop issues. This design enhances signal integrity and reliability. By following a simple maintenance routine, you can maximize the service life of the 190501-02-00-00 and avoid unexpected failures.

Compatibility and Integration

The 190501-02-00-00 is designed to work with Bently Nevada monitoring systems. Its standard MIL-C-5015 connector ensures easy integration with existing cabling. The output bias voltage and impedance are compatible with typical vibration monitoring modules. Always refer to the system manual for specific wiring and configuration requirements.
