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

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

In the evolution of industrial machinery monitoring, the need for reliable vibration sensing has never been greater. The 190501-01-00-CN from Bently Nevada addresses this demand with a robust design tailored for harsh environments. As a Velomitor CT velocity transducer, it converts mechanical vibration into an electrical signal, enabling predictive maintenance and reducing unplanned downtime.

This transducer is part of Bently Nevada's trusted product line, known for accuracy and durability. With a sensitivity of 3.94 mV/mm/s (±5%), it provides consistent output for condition monitoring systems. The 190501-01-00-CN is engineered to perform in temperatures ranging from -40°C to +85°C, making it suitable for demanding industrial settings.

Key Features and Technical Specifications

The 190501-01-00-CN offers several features that enhance its performance and ease of integration:

• Frequency Response: 3.0 Hz to 900 Hz (±1.0 dB) and 1.5 Hz to 1.0 kHz (±3.0 dB), covering a wide range of machine speeds.
• Output Bias Voltage: 10.1 Vdc ± 1.0 Vdc (Pin A referenced to Pin B), ensuring stable signal output.
• Dynamic Output Impedance: Less than 400 Ω typical, allowing compatibility with most monitoring systems.
• Transverse Response: Less than 5% of axial sensitivity, minimizing cross-axis errors.
• Amplitude Linearity: ±2% to 63.5 mm/s pk, ensuring accurate measurement across the operating range.
• Mounted Resonant Frequency: 9 kHz minimum (stud mounted), providing a high frequency response ceiling.
• Base Strain Sensitivity: 0.43 mm/s/μstrain, reducing false readings from mounting stress.
• Grounding: Internal electronics isolated from case, preventing ground loops.

These specifications make the 190501-01-00-CN a reliable choice for vibration monitoring in rotating machinery, such as pumps, motors, and fans.

Applications and Use Cases

The 190501-01-00-CN is ideal for various industrial applications where machinery health is critical. In manufacturing plants, it monitors vibration on production equipment, helping to detect bearing wear or imbalance early. In power generation, it provides data for turbine and generator condition assessment. Additionally, in petrochemical facilities, its robust construction withstands harsh environments while delivering accurate readings.

Because of its wide frequency response and high shock limit (5000 g pk), the transducer suits applications with high transient forces. Its 100% condensing humidity limit allows use in wet or washdown areas, provided it is not submerged.

Installation and Setup

Proper installation is key to achieving accurate measurements. The 190501-01-00-CN features a stud mounting option (3/8-in 24 to 3/8-in 24) and a MIL-C-5015 connection interface. Recommended mounting torque is 4.5 N-m ± 0.6 N-m (40 in-lbf ± 5 in-lbf). Ensure the mounting surface is clean and flat to avoid base strain effects.

For wiring, connect Pin A and Pin B as per the output bias voltage specification. The transducer can be mounted in any orientation, offering flexibility in tight spaces. Maximum cable length is 305 meters (1,000 ft.) with cable part number 02173006, without signal degradation.

Maintenance and Reliability

Routine maintenance of the 190501-01-00-CN is minimal due to its solid-state design. However, periodic inspection of the mounting integrity and cable condition is recommended. Check for any signs of corrosion or damage on the connector, especially in humid environments. The 316L stainless steel case provides excellent corrosion resistance, extending service life.

Given its low base strain sensitivity and magnetic field susceptibility (<0.0068 mm/s/gauss), the transducer maintains accuracy even in electrically noisy environments. This reliability reduces the need for frequent recalibration, contributing to lower lifecycle costs.

Compatibility and Integration

The 190501-01-00-CN is designed to work with Bently Nevada monitoring systems and other vibration data collectors. Its standard output signal (velocity) and low impedance allow direct connection to most industrial PLCs and DCSs. For hazardous area installations, the transducer offers optional intrinsic safety approvals (Ex ia IIC T4) as per the agency approval options, but the CN version is country-specific.

Always verify compatibility with your existing monitoring equipment before integration. For detailed wiring diagrams and system requirements, refer to the official Bently Nevada documentation.
