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

Product Overview

When unexpected machinery vibrations cause unplanned downtime, the Bently Nevada 190501-01-00-00 Velomitor CT Velocity Transducer delivers precise, reliable data to protect your assets. This velocity transducer converts mechanical motion into an electrical signal proportional to velocity, enabling early detection of bearing wear, imbalance, and misalignment. With a sensitivity of 3.94 mV/mm/s (100 mV/in/s) ±5%, it captures even subtle changes in machine condition, helping you schedule maintenance before failures occur.

Key Technical Specifications

• Sensitivity: 3.94 mV/mm/s (100 mV/in/s) ±5% – ensures accurate vibration measurement for trend analysis.
• 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 – covers most rotating machinery speeds.
• Output Bias Voltage: 10.1 Vdc ± 1.0 Vdc, Pin A referenced to Pin B – provides a stable baseline for signal processing.
• Operating Temperature: -40°C to +85°C (-40°F to +185°F) – suitable for harsh industrial environments.
• Case Material: 316L stainless steel – resists corrosion in demanding applications.
• Weight: <297 g (10.5 oz.) – lightweight for easy mounting.
• Mounting Torque: 4.5 N-m ± 0.6 N-m (40 in–lbf ± 5 in-lbf) – ensures consistent coupling.

These specs translate into reliable performance: the wide frequency range captures both low-speed and high-speed vibrations, while the robust stainless steel housing extends service life, reducing replacement costs.

Industry Applications

In pump and compressor monitoring, the 190501-01-00-00 detects early signs of cavitation or bearing degradation. Its 3.0 Hz low-end response picks up slow-speed rotational issues, while the 900 Hz upper limit covers blade pass frequencies. For fan and blower applications, the transducer’s 0.229 mm/s (0.009 in/s) pk broadband noise floor ensures clear signals even in noisy environments, minimizing false alarms that lead to unnecessary inspections.

Installation & Setup Guidance

Mount the transducer on a flat, clean surface using the included 3/8-in-24 stud. Apply the specified mounting torque of 4.5 N-m ± 0.6 N-m to ensure proper coupling without damaging the housing. The MIL-C-5015 connection interface simplifies wiring: connect Pin A (signal) and Pin B (common) per the polarity note – Pin A goes positive when velocity is from base to top. Use cable part number 02173006 for runs up to 305 metres (1,000 ft.) without signal degradation.

Maintenance & Reliability

The 190501-01-00-00 requires minimal maintenance due to its sealed 316L stainless steel construction and internal electronics isolated from the case. Periodically inspect the cable and connector for damage, especially in high-vibration or corrosive environments. The transducer withstands 5000 g pk shock and 100% condensing humidity, so it remains reliable in washdown areas. Regular calibration checks every 12 months help maintain measurement accuracy, extending the interval between replacements.

Selection Guide & Purchasing Advice

Before ordering, verify that the 190501-01-00-00 matches your machine’s vibration frequency range and temperature conditions. This model includes a 3/8-in-24 stud mount and MIL-C-5015 connector with no agency approvals. For intrinsically safe installations, consider the 190501 with Agency Approval Options 01 through 04.
