190501-01-00-01 | Bently Nevada 3.94 mV/mm/s Velocity Transducer

Introduction to the Bently Nevada 190501-01-00-01

When machine vibration threatens uptime, the 190501-01-00-01 from Bently Nevada provides accurate, continuous velocity measurement. This Velomitor CT velocity transducer is engineered for industrial rotating equipment, offering a rugged 316L stainless steel case and a wide operating temperature range. With its high sensitivity and intrinsic safety approvals, it suits harsh environments where reliable monitoring is critical.

Key Features and Technical Specifications

The 190501-01-00-01 delivers performance you can trust. Its electrical sensitivity is 3.94 mV/mm/s (100 mV/in/s) ±5%, ensuring precise velocity readings. The frequency response spans 3.0 Hz to 900 Hz (180 to 54,000 cpm) ±1.0 dB, with an extended range of 1.5 Hz to 1.0 kHz (90 to 60,000 cpm) ±3.0 dB. This wide bandwidth captures both slow-speed and high-speed vibration events.

• Sensitivity: 3.94 mV/mm/s ±5%
• Frequency Response: 3.0 Hz to 900 Hz ±1.0 dB
• Output Bias Voltage: 10.1 Vdc ± 1.0 Vdc
• Dynamic Output Impedance: <400 Ω typical
• Broadband Noise: 0.229 mm/s pk
• Base Strain Sensitivity: 0.43 mm/s/μstrain
• Operating Temperature: -40°C to +85°C
• Shock Limit: 5000 g pk

One standout feature is the internal electronics isolation from the case, which reduces ground loop interference. Additionally, the maximum cable length of 305 meters (1,000 ft.) with part number 02173006 ensures signal integrity over long runs, making it ideal for large facilities.

Applications and Use Cases

In petrochemical plants, the 190501-01-00-01 monitors pumps and compressors, helping prevent unexpected failures. Its ATEX/IECEx/CSA approvals (Class I, Division 1, and Zone 0/1) make it suitable for explosive atmospheres. For example, a refinery can install this transducer on a critical motor to detect bearing wear early, avoiding costly downtime. Similarly, in power generation, it tracks turbine vibration, supporting predictive maintenance programs.

Installation and Setup

Mounting the 190501-01-00-01 is straightforward. It uses a 3/8-24 stud mount, and the recommended mounting torque is 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. The MIL-C-5015 connection interface ensures a secure, reliable electrical connection. For best results, follow the installation drawing 167536, as specified for intrinsic safety compliance.

Maintenance and Reliability

Routine inspection is essential to maintain accuracy. Periodically check the mounting integrity and cable condition. The 316L stainless steel case resists corrosion, and the sealed design handles 100% condensing humidity. With a shock limit of 5000 g, it withstands severe mechanical impacts. Regular verification of the output bias voltage (10.1 Vdc ± 1.0 Vdc) can confirm proper operation.

Compatibility and Integration

The 190501-01-00-01 integrates seamlessly with Bently Nevada monitoring systems. Its standard velocity output (3.94 mV/mm/s) is compatible with most industrial vibration monitors. The MIL-C-5015 connector matches common cabling, and the 305-meter cable length supports remote installations. For hazardous areas, the intrinsic safety ratings (Ex ia IIC T4, AEx ia IIC T4) ensure safe integration into approved systems.

Comparison with Similar Transducers

Compared to standard velocity transducers, the 190501-01-00-01 offers a broader frequency range and higher shock tolerance. Many competitors lack the -40°C to +85°C operating range or the 5000 g shock rating. Additionally, its base strain sensitivity of 0.43 mm/s/μstrain is lower than typical, reducing false readings from mounting surface strain. This makes it a superior choice for demanding applications.
