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

Introduction to the 190501-02-00-00

When rotating machinery fails unexpectedly, the consequences can be costly. The 190501-02-00-00 from Bently Nevada provides the precise vibration data you need to detect problems early. This Velomitor CT Velocity Transducer is engineered for continuous monitoring in demanding industrial environments.

With a sensitivity of 3.94 mV/mm/s (100 mV/in/s) ±5%, this transducer converts mechanical vibration into an electrical signal that control systems can interpret. Its robust 316L stainless steel case and MIL-C-5015 connection interface ensure durability and reliable performance.

Key Features and Technical Specifications

The 190501-02-00-00 is built to deliver accurate, repeatable measurements. Here are the core specifications you can rely on:

• 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
• 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 signal degradation
• Operating Temperature: -40°C to +85°C (-40°F to +185°F)
• Shock Limit: 5000 g pk, maximum
• Humidity Limit: 100% condensing, non-submerged

One distinctive feature is the mounted resonant frequency of 9 kHz minimum (stud mounted, except quick disconnect). This high resonant frequency allows the transducer to operate accurately over a wide frequency range without distortion, making it suitable for high-speed machinery.

Applications and Use Cases

The 190501-02-00-00 is ideal for vibration monitoring on pumps, fans, motors, and other rotating equipment. Its wide frequency response and high shock limit make it suitable for both low-speed and high-speed machinery. For example, in a paper mill, this transducer can be mounted on a dryer roll bearing housing to detect imbalance or misalignment early, preventing unplanned downtime.

Moreover, the transducer's intrinsically safe options (Ex ia IIC T4 and AEx ia IIC T4) allow installation in hazardous areas when ordered with the appropriate agency approval option. This makes it a flexible choice for oil and gas, chemical, and other process industries.

Installation and Setup

Proper mounting is critical for accurate vibration measurement. The 190501-02-00-00 comes with a stud mounting option (3/8-in 24 to 1/2-in 20) that ensures a rigid connection to the machine surface. Follow these general guidelines:

• Prepare a flat, clean mounting surface (33 mm diameter minimum).
• Apply the recommended mounting torque of 4.5 N-m ± 0.6 N-m (40 in–lbf ± 5 in-lbf).
• Use the specified cable (part number 02173006) for optimal signal integrity.
• Ensure the connector is properly seated and secured.

The transducer can be mounted in any orientation, offering flexibility in tight spaces. Its internal electronics are isolated from the case, reducing ground loop issues.

Maintenance and Reliability

Routine inspection of the transducer and its mounting is essential for long-term reliability. Periodically check the mounting stud for tightness and inspect the cable for damage. The 316L stainless steel case provides excellent corrosion resistance, making it suitable for harsh environments.

Because the transducer has no moving parts, it requires minimal maintenance. However, environmental factors such as extreme temperatures and humidity can affect performance. The 190501-02-00-00 is rated for 100% condensing humidity and operates from -40°C to +85°C, so it can withstand most industrial conditions.

Compatibility and Integration

The 190501-02-00-00 is designed to work with Bently Nevada monitoring systems and other vibration monitoring equipment that accept standard velocity transducer inputs. Its MIL-C-5015 connection interface ensures a secure, standardized connection. For detailed integration guidance, refer to the official Bently Nevada documentation or contact Petro Auto Tech.
