190501-10-00-CN | Bently Nevada 100 mV/in/s Velocity Transducer

Introduction to the Bently Nevada 190501-10-00-CN

When machine vibration threatens uptime, the 190501-10-00-CN from Bently Nevada provides the precise measurement you need. This Velomitor CT velocity transducer converts mechanical motion into an electrical signal, enabling condition monitoring and predictive maintenance. With its rugged 316L stainless steel case and country-specific approval option, it is built for demanding industrial environments.

Key Features and Technical Specifications

The 190501-10-00-CN delivers consistent performance across a wide operating range. Its sensitivity of 3.94 mV/mm/s (100 mV/in/s) ±5% ensures accurate velocity readings. The frequency response spans 3.0 Hz to 900 Hz (180 to 54,000 cpm) ±1.0 dB, and extends to 1.5 Hz to 1.0 kHz (90 to 60,000 cpm) ±3.0 dB, covering typical rotating machinery vibration frequencies.

• 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 (0.017 in/s/μstrain)
• Maximum Cable Length: 305 meters (1,000 ft) with part number 02173006
• Operating Temperature: -40°C to +85°C (-40°F to +185°F)
• Shock Limit: 5000 g pk maximum
• Case Material: 316L stainless steel

The transducer's transverse response is less than 5% of axial sensitivity, ensuring accurate axial measurements. Amplitude linearity is ±2% to 63.5 mm/s pk (2.5 in/s pk), providing reliable data across the measurement range. The mounted resonant frequency is 9 kHz minimum (stud mounted, except quick disconnect), which supports high-frequency applications.

Applications and Use Cases

This velocity transducer suits turbomachinery, pumps, fans, and compressors where vibration monitoring is critical. Its wide frequency response captures both low-speed and high-speed machine dynamics. The 190501-10-00-CN is also ideal for gearboxes and rolling element bearings, where early fault detection reduces downtime. In addition, its robust construction makes it suitable for harsh environments, including those with high humidity or magnetic fields.

Installation and Setup

Mounting is straightforward with the provided plate stud M6x1 to M6x1 with 3/8-24 adapter. The mounting torque is 4.5 N-m ± 0.6 N-m (40 in-lbf ± 5 in-lbf). The transducer can be mounted at any orientation, offering flexibility in tight spaces. The MIL-C-5015 connection interface ensures a secure, reliable electrical connection. For best results, follow the manufacturer's installation drawing and ensure the mounting surface is clean and flat.

Maintenance and Reliability

Routine inspection is essential to maintain performance. Check the mounting integrity and connector tightness periodically. The internal electronics are isolated from the case, reducing ground loop issues. With a storage temperature range of -40°C to +100°C, the transducer withstands harsh storage conditions. Its 316L stainless steel case resists corrosion, extending service life and lowering total cost of ownership.

Compatibility and Integration

The 190501-10-00-CN is compatible with Bently Nevada monitoring systems and data acquisition equipment. Its standard MIL-C-5015 connector integrates easily with existing cabling. The transducer's output bias voltage and impedance allow direct connection to most vibration monitors. For new installations, verify compatibility with your system's input requirements.

Troubleshooting and Common Issues

If readings appear erratic, first check the cable and connector for damage. Ensure the mounting torque is within specification to avoid resonance issues. If the output bias voltage is outside 10.1 Vdc ± 1.0 Vdc, the transducer may need replacement. Refer to the official Bently Nevada manual for detailed diagnostics.
