190501-09-00-CN | Bently Nevada Velomitor CT Velocity Transducer

What Makes the 190501-09-00-CN a Reliable Choice for Vibration Monitoring?

When rotating machinery fails, unplanned downtime can cost thousands per hour. The 190501-09-00-CN from Bently Nevada helps you catch problems early. This Velomitor CT velocity transducer converts mechanical vibration into an electrical signal. That signal feeds your monitoring system. You get real-time insight into machine health. This proactive approach reduces costly surprises.

This transducer is built for industrial environments. Its 316L stainless steel case resists corrosion. The MIL-C-5015 connection interface ensures a secure, reliable link. With a weight of just 0.297 kg, it is easy to handle during installation. The compact design fits tight spaces. This makes it a practical upgrade for existing machinery.

Key Features and Technical Specifications

The 190501-09-00-CN offers performance you can trust. Here are the core 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 the operating temperature range.
• Transverse Response: Less than 5% of the 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).
• Grounding: Internal electronics are isolated from case.
• Maximum Cable Length: 305 metres (1,000 ft.) of cable (part number 02173006) with no degradation of signal.

These specs show a transducer designed for accuracy. The low transverse response minimizes errors from cross-axis motion. The high resonant frequency avoids interference in most industrial applications. The isolated grounding reduces electrical noise. This ensures clean signals for your monitoring system.

Real-World Applications and Use Cases

This transducer suits a wide range of rotating equipment. Use it on pumps, motors, fans, and compressors. It works well in turbines and gearboxes too. The operating temperature range of -40°C to +85°C (-40°F to +185°F) handles harsh environments. The shock limit of 5000 g pk ensures survival in demanding conditions. The humidity limit of 100% condensing (non-submerged) adds versatility. For example, a petrochemical plant can monitor its cooling fans. The transducer’s robust design handles the outdoor elements. This leads to fewer false alarms and better maintenance planning.

Installation and Setup

Proper installation is key to accurate readings. The mounting hardware option includes a plate stud 3/8-in 24 to 1/4-in NPT. This provides a solid, stable mount. The mounting torque should be 4.5 N-m ± 0.6 N-m (40 in-lbf ± 5 in-lbf). This ensures the transducer is secure without damaging threads. The mounting angle is any orientation, which simplifies placement. The connection option uses a MIL-C-5015 interface. This is a standard, reliable connector. Follow the manufacturer’s manual for detailed wiring instructions. Always verify the correct pin connections. Pin A goes positive with respect to Pin B when velocity is from base to top. This polarity is critical for proper signal interpretation.

Maintenance and Reliability

Regular inspection extends the life of your transducer. Check the mounting integrity periodically. Look for any signs of corrosion or damage. The 316L stainless steel case resists most chemicals. However, environmental factors can still affect performance. The temperature sensitivity is -8% to +5% typical over the operating range. This means readings may vary slightly with temperature. Account for this in your monitoring system. The internal electronics are isolated from the case. This reduces the risk of ground loops. With proper care, this transducer provides years of reliable service. This reliability translates to lower maintenance costs and less downtime.

Compatibility and Integration

The 190501-09-00-CN is part of the Bently Nevada family of monitoring solutions. It works with compatible Bently Nevada monitors and systems. The output signal is a standard velocity signal. This makes integration straightforward. The maximum cable length of 305 metres (1,000 ft.) allows flexible placement. You can install the transducer far from the monitoring equipment. This is useful in large facilities. For specific compatibility details, refer to the official Bently Nevada documentation. Petro Auto Tech can also provide guidance.
