190501-02-00-01 | Bently Nevada Velomitor CT Velocity Transducer

Introduction to the 190501-02-00-01 Velomitor CT Velocity Transducer

When rotating machinery experiences unexpected vibration, the 190501-02-00-01 from Bently Nevada provides the precise measurement needed to diagnose issues early. This Velomitor CT velocity transducer is engineered for industrial environments where accuracy and durability are non-negotiable.

With a sensitivity of 3.94 mV/mm/s (±5%), the transducer converts mechanical velocity into a clear electrical signal, enabling condition monitoring teams to track machine health in real time. Its robust 316L stainless steel case and MIL-C-5015 connection interface ensure dependable operation in demanding settings.

Key Features and Technical Specifications

The 190501-02-00-01 offers a range of performance parameters that make it suitable for permanent vibration monitoring on pumps, fans, motors, and other rotating equipment.

• 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.
• Broadband Noise: 0.229 mm/s (0.009 in/s) pk.
• Base Strain Sensitivity: 0.43 mm/s/μstrain (0.017 in/s/μstrain).
• Transverse Response: Less than 5% of axial sensitivity.
• Amplitude Linearity: ±2% to 63.5 mm/s pk (2.5 in/s pk).
• Mounted Resonant Frequency: 9 kHz minimum (stud mounted).
• Temperature Sensitivity: -8% to +5% typical over operating range.

These specifications ensure that the transducer delivers consistent, repeatable data, which is critical for trend analysis and predictive maintenance programs.

Applications and Use Cases

The 190501-02-00-01 is designed for permanent installation on industrial machinery where continuous vibration monitoring is required. Typical applications include:

• Pumps and compressors
• Electric motors and generators
• Fans and blowers
• Centrifuges and turbines

Because the transducer is hermetically sealed and rated for 100% condensing humidity (non-submerged), it can be installed in washdown areas or outdoor environments without concern. The wide operating temperature range of -40°C to +85°C (-40°F to +185°F) further extends its usability across climates.

Installation and Mounting

Proper installation is essential to achieve accurate readings. The 190501-02-00-01 comes with a stud mounting option (3/8-in 24 to 1/2-in 20) 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).

The transducer can be mounted in any orientation, and its internal electronics are isolated from the case, reducing the risk of ground loops. For best results, mount the transducer directly on the machine bearing housing or other rigid surface, ensuring a flat, clean contact area.

Maximum cable length is 305 meters (1,000 ft) using Bently Nevada part number 02173006, with no signal degradation. This allows flexibility in locating the monitoring system away from the machine.

Maintenance and Reliability

Because the 190501-02-00-01 has no moving parts, it requires minimal maintenance. However, periodic inspection of the mounting integrity and cable condition is recommended to ensure long-term reliability.

The transducer’s 316L stainless steel case resists corrosion, and its ability to withstand 5000 g pk shock makes it resilient in harsh industrial environments. These features contribute to reduced downtime and lower total cost of ownership.

Environmental and Agency Approvals

The 190501-02-00-01 (Agency Approval Option 01) carries CSA/NRTL/C (Class I, Division 1) and ATEX/IECEx/CSA (Class I, Zone 0/1) approvals. It is rated intrinsically safe Ex ia IIC T4 and AEx ia IIC T4, suitable for hazardous areas.

Operating temperature for the approved version is -40°C to +100°C (-40°F to +212°F). Installation must follow drawing 167536 to maintain safety compliance.

Why Choose the 190501-02-00-01?

For plant engineers and maintenance professionals, the 190501-02-00-01 offers a combination of accuracy, durability, and safety that is hard to match. Its high sensitivity and wide frequency range make it suitable for detecting both low-speed and high-speed machinery faults.

Moreover, the transducer’s internal grounding isolation and low base strain sensitivity minimize measurement errors, ensuring that the data you collect truly reflects machine condition.
