190501-00-00-00 | Bently Nevada Velocity Transducer

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

When machinery vibration threatens uptime, the 190501-00-00-00 from Bently Nevada provides a dependable measurement solution. This Velomitor CT velocity transducer is engineered for industrial environments where accurate velocity data is critical. With a sensitivity of 3.94 mV/mm/s (100 mV/in/s) ±5%, it delivers consistent performance for predictive maintenance programs.

Part of the trusted Bently Nevada family, this transducer is built to withstand harsh conditions. Its 316L stainless steel case and MIL-C-5015 connection interface ensure durability and reliable signal transmission. The 190501-00-00-00 is a direct replacement for older velocity transducers, offering modern reliability without requiring system redesign.

Key Features and Technical Specifications

The 190501-00-00-00 stands out with several performance-oriented specifications:

• Sensitivity: 3.94 mV/mm/s (100 mV/in/s) ±5%
• 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
• Temperature Sensitivity: -8% to +5% typical over operating 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)
• 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 isolated from case
• Maximum Cable Length: 305 meters (1,000 ft) with no signal degradation

These specifications make the 190501-00-00-00 suitable for a wide range of rotating machinery monitoring tasks. Its wide frequency response captures both low-speed and high-speed vibrations, while the low transverse response minimizes measurement errors from cross-axis motion.

Applications and Use Cases

In industrial plants, unplanned downtime is costly. The 190501-00-00-00 helps prevent this by providing accurate velocity data for condition monitoring. It is ideal for monitoring pumps, fans, compressors, and motors where early detection of imbalance or bearing wear is essential.

For example, in a petrochemical facility, the transducer can be mounted on critical rotating equipment to track vibration trends. Its robust design and wide operating temperature range (-40°C to +85°C) make it suitable for outdoor or high-temperature environments. Additionally, the 100% condensing humidity limit ensures reliable operation in humid conditions without submersion.

Installation and Setup

Proper installation is key to obtaining accurate readings. The 190501-00-00-00 features a mounting surface of 33 mm diameter and a height of 82 mm. It can be mounted in any orientation, offering flexibility in tight spaces. The recommended mounting torque is 4.5 N-m ± 0.6 N-m (40 in-lbf ± 5 in-lbf) to ensure a secure and stable mount.

The transducer uses a 2-pin 316L stainless steel MIL-C-5015 connector (top exit). When connecting, ensure that Pin A goes positive with respect to Pin B when velocity is from base to top. This polarity is critical for correct signal interpretation. For installations requiring long cable runs, the maximum cable length of 305 meters (1,000 ft) allows flexibility without signal degradation.

Maintenance and Reliability

Routine maintenance of the 190501-00-00-00 is minimal, but periodic inspection is recommended. Check the mounting integrity and connector condition regularly to prevent loosening or corrosion. The 316L stainless steel case provides excellent corrosion resistance, reducing the need for frequent replacements.

Because the transducer has no moving parts, it offers long-term reliability. Its shock limit of 5000 g pk ensures it can withstand severe impacts without damage. By integrating this transducer into a predictive maintenance program, you can reduce unexpected failures and extend equipment life, ultimately saving on repair costs and downtime.

Compatibility and Integration

The 190501-00-00-00 is designed to work with Bently Nevada monitoring systems and other compatible vibration monitoring equipment. Its standard MIL-C-5015 connector simplifies integration into existing setups. The output bias voltage of 10.1 Vdc is compatible with most data acquisition systems.

For new installations, the transducer can be paired with Bently Nevada monitors or third-party systems that accept velocity inputs. Always verify compatibility with your specific monitoring hardware before installation.

Troubleshooting and Common Issues

If you experience erratic readings, first check the cable and connector for damage. Ensure the mounting torque is within the specified range to avoid resonance issues. If the output bias voltage is outside 10.1 Vdc ± 1.0 Vdc, the transducer may be faulty and should be replaced.

Another common issue is incorrect polarity. Double-check that Pin A is connected to the positive input of your monitoring system. For detailed troubleshooting, refer to the official Bently Nevada documentation or contact Petro Auto Tech for technical support.
