190501-11-00-00 | Bently Nevada 3.94 mV/mm/s Velocity Transducer

Why Choose the Bently Nevada 190501-11-00-00 Velomitor CT?

When rotating machinery faces unpredictable vibration, unplanned downtime becomes a costly reality. The 190501-11-00-00 from Bently Nevada offers a dependable solution. This Velomitor CT velocity transducer measures absolute bearing housing vibration. It converts mechanical motion into a proportional electrical signal. That signal helps you monitor machine health continuously. With its robust design, it suits demanding industrial environments.

This transducer is engineered for precision. It delivers a sensitivity of 3.94 mV/mm/s (100 mV/in/s) with ±5% tolerance. That means accurate readings you can trust. The frequency response spans 3.0 Hz to 900 Hz (180 to 54,000 cpm) within ±1.0 dB. It extends to 1.5 Hz to 1.0 kHz (90 to 60,000 cpm) within ±3.0 dB. Such range covers typical rotating equipment vibrations. You can detect early signs of imbalance, misalignment, or bearing wear.

Key Features and Technical Specifications

The 190501-11-00-00 is packed with features that enhance reliability. Here are the core specs from the datasheet:

• 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.
• 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 metres (1,000 ft) with part number 02173006.

These specifications ensure consistent performance. The transducer operates from -40°C to +85°C (-40°F to +185°F). Storage temperature ranges from -40°C to +100°C (-40°F to +212°F). It withstands shock up to 5000 g pk. Humidity limit is 100% condensing, non-submerged. Magnetic field susceptibility is <0.0068 mm/s/gauss (0.268 mil/s/gauss) at 50 gauss, 50-60 Hz.

Applications and Use Cases

This velocity transducer fits various rotating machinery. Common applications include pumps, motors, fans, and compressors. It also works on turbines and gearboxes. In each case, it provides critical vibration data. That data helps predict failures before they happen. For example, in a petrochemical plant, continuous monitoring prevents catastrophic breakdowns. The transducer's rugged construction handles harsh conditions. Its 316L stainless steel case resists corrosion. Therefore, it suits offshore and chemical environments.

Installation and Setup

Proper installation ensures accurate readings. The 190501-11-00-00 comes with a mounting hardware option: 1 1 plate stud 3/8-in 24 to 1/4-in 28. That allows secure attachment to the machine surface. The connection option uses a MIL-C-5015 interface. This provides a reliable electrical connection. 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. That flexibility simplifies installation. Ensure the mounting surface is clean and flat. A 33 mm diameter (1.3 in) surface is required. Follow the manufacturer's manual for detailed steps.

Maintenance and Reliability

Routine maintenance is straightforward. Periodically inspect the transducer and cable for damage. Verify that mounting bolts remain tight. Check the output signal for consistency. Because the electronics are isolated from the case, ground loops are minimized. That enhances signal integrity. The transducer's design reduces maintenance needs. With proper care, it provides years of reliable service. This reliability translates to lower total cost of ownership. You spend less on replacements and repairs.

Compatibility and Integration

The 190501-11-00-00 integrates easily with Bently Nevada monitoring systems. Its standard output works with most vibration monitors. The MIL-C-5015 connector ensures compatibility with existing cabling. The maximum cable length of 305 metres (1,000 ft) allows flexible placement. You can position the monitor away from the machine. This reduces exposure to heat and vibration. For new installations, plan the cable route carefully. Avoid sharp bends and abrasive surfaces.
