190501-10-00-CN | Bently Nevada Velomitor CT Velocity Transducer

Introduction to the Bently Nevada 190501-10-00-CN Velomitor CT Velocity Transducer

When rotating machinery begins to exhibit abnormal vibration, identifying the root cause quickly is critical to preventing unplanned downtime. The 190501-10-00-CN from Bently Nevada is a Velomitor CT velocity transducer engineered to provide accurate, repeatable vibration data in demanding industrial environments. With its robust 316L stainless steel case and high-temperature tolerance, this transducer is built for continuous operation in harsh conditions.

As part of the Velomitor CT series, the 190501-10-00-CN offers a frequency response of 3.0 Hz to 900 Hz (±1.0 dB) and an extended range of 1.5 Hz to 1.0 kHz (±3.0 dB), making it suitable for a wide range of rotating equipment. Its sensitivity of 3.94 mV/mm/s (100 mV/in/s) ±5% ensures precise velocity measurement, which is essential for effective condition monitoring.

Key Features and Technical Specifications

The 190501-10-00-CN is designed with performance and durability in mind. Below are the key specifications that define its capabilities:

• Product Type: Velomitor CT Velocity Transducer
• 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
• Operating Temperature: -40°C to +85°C (-40°F to +185°F)
• Shock Limit: 5000 g pk, maximum
• Case Material: 316L stainless steel
• Mounting Torque: 4.5 N-m ± 0.6 N-m (40 in–lbf ± 5 in-lbf)

One of the most distinctive features of this transducer is its broadband noise floor of 0.229 mm/s (0.009 in/s) pk, which ensures that even small vibration signals are captured clearly. Additionally, the internal electronics are isolated from the case, reducing the risk of ground loops and improving signal integrity.

Applications and Use Cases

The 190501-10-00-CN is ideal for monitoring vibration on critical rotating machinery such as pumps, fans, compressors, and turbines. Its wide frequency response and high shock rating make it suitable for both low-speed and high-speed equipment. In addition, the transducer's ability to operate in condensing humidity (100% condensing, non-submerged) allows it to be used in washdown areas or humid environments without performance degradation.

For example, in a petrochemical plant, the 190501-10-00-CN can be installed on a cooling water pump to detect early signs of bearing wear or imbalance. By providing reliable velocity data, it enables maintenance teams to schedule repairs before a catastrophic failure occurs, thereby reducing downtime and maintenance costs.

Installation and Setup

Proper installation is essential to obtain accurate measurements. The 190501-10-00-CN comes with a mounting hardware option that includes a plate stud M6x1 to M6x1 with a 3/8-24 adapter, allowing flexible mounting configurations. The transducer can be mounted in any orientation, and the recommended mounting torque is 4.5 N-m ± 0.6 N-m (40 in–lbf ± 5 in-lbf) to ensure a secure and stable attachment.

The connection interface is a 2-pin 316L stainless steel MIL-C-5015 connector, which provides a rugged and reliable electrical connection. When routing cables, ensure that the maximum cable length of 305 metres (1,000 ft.) is not exceeded to avoid signal degradation. For detailed wiring instructions, refer to the installation drawing 167536, which is applicable for agency-approved versions.

Maintenance and Reliability

Routine maintenance of the 190501-10-00-CN is minimal due to its robust design. However, periodic inspection is recommended to verify that the mounting hardware remains tight and the connector is clean and free from corrosion. The transducer's 316L stainless steel case offers excellent resistance to corrosive environments, extending its service life and reducing the need for frequent replacements.

Given its high shock limit of 5000 g pk, the transducer can withstand severe mechanical shocks without damage, making it a reliable choice for applications where vibration levels may spike unexpectedly. By investing in a high-quality transducer like the 190501-10-00-CN, you can achieve lower total cost of ownership through reduced downtime and longer maintenance intervals.

Compatibility and Integration

The 190501-10-00-CN is designed to work with Bently Nevada monitoring systems and can be integrated into most vibration monitoring platforms that accept standard velocity transducer inputs. Its output bias voltage of 10.1 Vdc and dynamic output impedance of <400 Ω make it compatible with typical data acquisition systems.
