190501-11-00-00 | Bently Nevada 100 mV/in/s Velocity Transducer

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

When unplanned downtime threatens your production line, accurate vibration measurement is critical. The 190501-11-00-00 from Bently Nevada provides the precise data you need to detect machinery faults early. This velocity transducer converts mechanical vibration into an electrical signal, enabling condition monitoring that protects your rotating equipment.

As a Velomitor CT model, it is designed for continuous, reliable operation in demanding industrial environments. Its robust construction and proven technology make it a trusted choice for maintenance teams seeking to extend asset life and reduce costly repairs.

Key Features and Technical Specifications

The 190501-11-00-00 offers a range of performance parameters that ensure accurate and repeatable measurements:

• Sensitivity: 3.94 mV/mm/s (100 mV/in/s) ±5%.
• 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.
• Output Bias Voltage: 10.1 Vdc ± 1.0 Vdc, Pin A referenced to Pin B.
• Dynamic Output Impedance: <400 Ω typical.
• Operating Temperature: -40°C to +85°C (-40°F to +185°F).
• Shock Limit: 5000 g pk, maximum.
• Humidity Limit: 100% condensing, non-submerged.
• Case Material: 316L stainless steel.

One standout feature is the broadband noise floor of 0.229 mm/s (0.009 in/s) pk. This low noise level ensures that even small vibration signals are not masked, providing cleaner data for early fault detection. This is particularly valuable in slow-speed machinery where subtle changes matter.

Installation and Mounting

Proper installation is essential for accurate readings. The 190501-11-00-00 includes a plate stud mounting option (3/8-in 24 to 1/4-in 28) and uses a MIL-C-5015 connection interface. The 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, offering flexibility in tight spaces.

For best results, ensure the mounting surface is clean and flat. The 33 mm diameter mounting surface provides a stable base. The internal electronics are isolated from the case, reducing the risk of ground loops that can distort signals.

Reliability and Maintenance

The 190501-11-00-00 is built to withstand harsh conditions. Its 316L stainless steel case resists corrosion, and the unit can operate in condensing humidity without submersion. With a maximum cable length of 305 meters (1,000 ft.) using part number 02173006, you can place the transducer away from the machine without signal degradation.

Routine maintenance is minimal. Periodically inspect the mounting stud and connector for tightness and signs of wear. Verify the output bias voltage at the monitor to ensure the transducer is functioning correctly. Following these simple checks helps maintain long-term reliability.

Applications and Use Cases

The 190501-11-00-00 is suitable for a wide range of rotating machinery, including pumps, fans, compressors, and motors. Its frequency response covers typical machine vibration ranges, making it ideal for general-purpose monitoring. The low transverse response (less than 5% of axial sensitivity) ensures that measurements reflect true axial motion, reducing false alarms.

In a typical scenario, a plant engineer installs the transducer on a critical pump bearing housing. The continuous signal feeds into a vibration monitoring system, alerting the team to increasing vibration levels. Early detection allows for planned maintenance, avoiding unexpected failure and production loss.

Compatibility and Integration

This transducer works with Bently Nevada monitoring systems that accept velocity inputs. The MIL-C-5015 connector ensures a secure, standard interface. For detailed integration guidance, refer to the official Bently Nevada documentation or contact Petro Auto Tech for support.
