190501-01-00-01 | Bently Nevada Velomitor CT Velocity Transducer

Introduction to the 190501-01-00-01

When machinery vibration threatens uptime, the 190501-01-00-01 from Bently Nevada provides a reliable measurement solution. This Velomitor CT velocity transducer is engineered for continuous monitoring in demanding environments. It offers a direct, high-level output that simplifies integration with monitoring systems.

Because it is a velocity transducer, the 190501-01-00-01 measures casing vibration directly. This makes it a practical choice for rotating equipment such as pumps, motors, and fans. Its robust construction and certified safety options support use in hazardous areas.

Key Features and Technical Specifications

The 190501-01-00-01 is built to deliver consistent performance. Here are the core specifications you can expect:

• 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; extends to 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.
• 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 metres (1,000 ft.) of cable (part number 02173006) with no degradation of signal.
• Operating Temperature: -40°C to +85°C (-40°F to +185°F).
• Shock Limit: 5000 g pk, maximum.
• Humidity Limit: 100% condensing, non-submerged.
• Magnetic Field Susceptibility: <0.0068 mm/s/gauss (0.268 mil/s/gauss) @ 50 gauss, 50-60Hz.
• Case Material: 316L stainless steel.
• Mounting Torque: 4.5 N-m ± 0.6 N-m (40 in–lbf ± 5 in-lbf).
• Weight: <297 g (10.5 oz.), typical.

One distinctive feature is the internal electronics being isolated from the case. This design helps reduce ground loop issues, which can affect signal integrity. Additionally, the transducer can be mounted in any orientation, offering flexibility during installation.

Applications and Use Cases

The 190501-01-00-01 is well-suited for vibration monitoring on rotating machinery. Common applications include pumps, compressors, motors, and turbines. Its frequency response covers from 3.0 Hz to 900 Hz, making it effective for detecting both low-speed and high-speed machinery faults.

For example, in a pump monitoring scenario, the transducer can detect imbalance or bearing wear early. This allows maintenance teams to plan repairs before a catastrophic failure occurs. The transducer's robust design also supports use in harsh industrial environments.

Installation and Setup

Proper installation is critical for accurate readings. The 190501-01-00-01 uses a stud mounting option (3/8-in 24 to 3/8-in 24). Ensure the mounting surface is clean and flat. Apply the recommended mounting torque of 4.5 N-m ± 0.6 N-m to secure the transducer.

The connection interface is a MIL-C-5015 connector. This provides a reliable, weatherproof connection. For best results, use the specified cable (part number 02173006) up to 305 metres (1,000 ft.) without signal degradation. Always follow the manufacturer's installation drawing (167536) for hazardous area installations.

Maintenance and Reliability

Routine maintenance helps ensure long-term reliability. Periodically inspect the transducer and its cable for physical damage. Verify that the mounting remains tight and that the connector is secure. Because the case is 316L stainless steel, it resists corrosion in most industrial environments.

The transducer has no moving parts, which reduces wear. However, environmental factors like extreme temperatures or vibration can affect performance. Regular checks of the output bias voltage can help confirm the transducer is functioning correctly.

Compatibility and Integration

The 190501-01-00-01 is designed to work with Bently Nevada monitoring systems. Its high-level output (10.1 Vdc bias) simplifies interface with standard vibration monitors. The transducer is also approved for use in intrinsically safe applications (Ex ia IIC T4, AEx ia IIC T4) when installed per drawing 167536.

For non-incendive applications, it meets Ex nL IIC T4 and AEx nA T4 ratings. This makes it versatile for various hazardous area classifications. Always verify system compatibility with your specific monitoring equipment.

Buyer's Guide: Evaluating the 190501-01-00-01

When selecting a velocity transducer, consider the following factors:

• Measurement range: The 190501-01-00-01 covers 3.0 Hz to 900 Hz, suitable for most rotating machinery.
• Environmental ratings: Operating temperature from -40°C to +85°C and 100% condensing humidity.
• Safety certifications: Intrinsically safe options for hazardous areas.
• Mounting flexibility: Any orientation, stud mount.
• Signal integrity: Internal isolation from case, low impedance output.

These features make the 190501-01-00-01 a strong candidate for predictive maintenance programs. Its robust design and certified safety options provide confidence in critical applications.
