Introduction to the Bently Nevada 190501-11-00-00

When machinery vibration threatens uptime, the 190501-11-00-00 from Bently Nevada provides accurate, continuous velocity measurement. This Velomitor CT velocity transducer is engineered for industrial environments where reliability is non-negotiable. With a sensitivity of 3.94 mV/mm/s (±5%), it converts mechanical vibration into a clear electrical signal. Maintenance engineers trust this sensor for predictive maintenance programs. It helps detect early signs of bearing wear, unbalance, and misalignment.

Key Features and Technical Specifications

The 190501-11-00-00 offers a robust set of specifications designed for demanding applications. Its frequency response covers 3.0 Hz to 900 Hz (±1.0 dB) and extends to 1.5 Hz to 1.0 kHz (±3.0 dB). This range captures both low-speed and high-speed machinery vibrations. The transducer operates across a wide temperature range, from -40°C to +85°C, ensuring performance in harsh environments.

• Sensitivity: 3.94 mV/mm/s (100 mV/in/s) ±5%
• Frequency Response: 3.0 Hz to 900 Hz (±1.0 dB); 1.5 Hz to 1.0 kHz (±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
• Maximum Cable Length: 305 metres (1,000 ft) with no signal degradation
• Shock Limit: 5000 g pk maximum
• Humidity Limit: 100% condensing, non-submerged

These specifications ensure accurate vibration data even in challenging conditions. The transducer's internal electronics are isolated from the case, reducing ground loop issues. Its 316L stainless steel case and connector provide excellent corrosion resistance.

Applications and Use Cases

The 190501-11-00-00 is ideal for monitoring rotating equipment such as pumps, motors, fans, and compressors. In petrochemical plants, it helps prevent unplanned downtime by providing early warning of mechanical faults. For maintenance engineers, this transducer simplifies vibration analysis, enabling condition-based maintenance rather than costly reactive repairs. Its robust design suits both indoor and outdoor installations, including hazardous areas when approved options are selected.

Installation and Setup

Proper installation is critical for accurate vibration measurement. The transducer comes with a mounting hardware option: a plate stud 3/8-in 24 to 1/4-in 28. This allows secure mounting to machinery surfaces. The connection interface uses a MIL-C-5015 connector, ensuring a reliable electrical connection. Recommended mounting torque is 4.5 N-m ± 0.6 N-m (40 in-lbf ± 5 in-lbf). The transducer can be mounted in any orientation, offering flexibility in tight spaces. For best results, ensure the mounting surface is clean and flat. Follow the manufacturer's manual for detailed wiring instructions.

Maintenance and Reliability

Routine inspection of the 190501-11-00-00 ensures long-term reliability. Check the mounting integrity periodically, as loose studs can affect readings. Verify the cable condition for signs of wear or damage. The transducer's sealed design protects against moisture and dust, reducing maintenance frequency. With a storage temperature range of -40°C to +100°C, it withstands harsh storage conditions. Regular calibration checks help maintain measurement accuracy. By investing in this reliable sensor, you reduce the risk of unexpected failures and extend machinery life.

Compatibility and Integration

The 190501-11-00-00 integrates seamlessly with Bently Nevada monitoring systems and other data acquisition equipment. Its standard MIL-C-5015 connector simplifies wiring. The output bias voltage of 10.1 Vdc is compatible with most vibration monitoring modules. For extended cable runs up to 305 metres, use the specified cable (part number 02173006) to maintain signal integrity. This transducer works with existing vibration analysis software, making it a drop-in replacement for older models.
