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

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

When machine vibration threatens uptime, the 190501-00-00-00 from Bently Nevada provides accurate velocity measurements. This Velomitor CT velocity transducer is engineered for industrial rotating machinery. It converts mechanical vibration into an electrical signal. That signal helps maintenance teams detect faults early.

The 190501-00-00-00 features a sensitivity of 3.94 mV/mm/s (100 mV/in/s) with ±5% tolerance. Its frequency response covers 3.0 Hz to 900 Hz (180 to 54,000 cpm) within ±1.0 dB. An extended range of 1.5 Hz to 1.0 kHz (90 to 60,000 cpm) is available within ±3.0 dB. This makes it suitable for a wide range of rotational speeds.

Key Features and Technical Specifications

The 190501-00-00-00 offers several performance characteristics that support reliable vibration monitoring.

• Output bias voltage: 10.1 Vdc ± 1.0 Vdc, Pin A referenced to Pin B.
• Dynamic output impedance: less than 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).
• 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, except quick disconnect).
• Grounding: internal electronics isolated from case.

These specs ensure accurate vibration data. The transducer operates over a temperature range of -40°C to +85°C (-40°F to +185°F). It can withstand shock up to 5000 g pk. Humidity limit is 100% condensing, non-submerged. Magnetic field susceptibility is less than 0.0068 mm/s/gauss (0.268 mil/s/gauss) at 50 gauss, 50-60 Hz.

Applications and Use Cases

The 190501-00-00-00 is ideal for monitoring rotating equipment such as pumps, fans, and motors. Its frequency response covers typical machine rotational speeds. The broad range from 1.5 Hz to 1.0 kHz helps detect both low-speed and high-speed faults. This transducer is often used in predictive maintenance programs. By providing continuous vibration data, it supports early diagnosis of bearing wear, unbalance, and misalignment.

Because of its robust design, the 190501-00-00-00 suits harsh industrial environments. The 316L stainless steel case resists corrosion. The MIL-C-5015 connection interface ensures a secure electrical connection. With a mounting surface of 33 mm diameter and height of 82 mm, it fits into tight spaces.

Installation and Setup

Proper installation is critical for accurate readings. The 190501-00-00-00 can be mounted in any orientation. Mounting torque should be 4.5 N-m ± 0.6 N-m (40 in-lbf ± 5 in-lbf). The transducer uses a 2-pin 316L stainless steel MIL-C-5015 connector on top. Ensure the mounting surface is clean and flat. The unit weighs less than 297 g (10.5 oz), so it is easy to handle.

For maximum cable length, up to 305 metres (1,000 ft) of cable (part number 02173006) can be used without signal degradation. This flexibility allows installation far from monitoring equipment. Always follow the manufacturer's installation drawing for best results.

Maintenance and Reliability

Regular inspection helps maintain performance. Check the mounting integrity periodically. Verify that the connector remains tight and free of corrosion. The internal electronics are isolated from the case, which reduces ground loop issues. The transducer is designed for long-term reliability in demanding conditions.

Because the 190501-00-00-00 has no moving parts, it requires minimal maintenance. Its solid-state design contributes to extended service life. This reduces downtime and replacement costs over time.

Compatibility and Integration

The 190501-00-00-00 is compatible with Bently Nevada monitoring systems that accept velocity transducer inputs. The output bias voltage of 10.1 Vdc is standard for many data acquisition modules. The MIL-C-5015 connector is widely used in industrial applications. Check your system's input specifications to ensure compatibility.

Troubleshooting and Common Issues

If vibration readings appear erratic, first check the cable connection. A loose connector can cause intermittent signals. Verify that the mounting torque is within specification. Excessive torque can stress the transducer. Insufficient torque may lead to inaccurate measurements.

Temperature extremes can affect sensitivity. The transducer has a temperature sensitivity variation of -8% to +5% typical over the operating range. If readings drift, consider the ambient temperature. Also, ensure the transducer is not exposed to condensing humidity beyond its limit.
