190501-00-00-00 | Bently Nevada 100 mV/in/s Velocity Transducer

What Makes the 190501-00-00-00 a Smart Choice for Vibration Monitoring?

When unplanned downtime threatens your rotating machinery, accurate vibration data is your first line of defense. The 190501-00-00-00 from Bently Nevada is a Velomitor CT velocity transducer engineered to deliver precise, repeatable measurements in demanding industrial environments. This model combines a rugged 316L stainless steel case with a proven sensing element, making it a dependable component for condition monitoring systems.

With a sensitivity of 3.94 mV/mm/s (100 mV/in/s) ±5%, the transducer converts mechanical velocity into a clear electrical signal. This allows maintenance teams to detect developing faults early, reducing the risk of catastrophic failure. The 190501-00-00-00 is designed for continuous operation across a wide temperature range, ensuring consistent performance even in harsh conditions.

Key Features and Technical Specifications of the 190501-00-00-00

Every specification of the 190501-00-00-00 is carefully chosen to support reliable vibration monitoring. Here are the critical parameters you can expect:

• 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)
• Operating Temperature: -40°C to +85°C (-40°F to +185°F)
• Shock Limit: 5000 g pk, maximum
• Case Material: 316L stainless steel
• Weight: <297 g (10.5 oz.), typical

One distinctive feature is the mounted resonant frequency of 9 kHz minimum (stud mounted, except quick disconnect). This high resonant frequency ensures that the transducer's response remains flat across the measurement range, minimizing errors from structural resonance. This is particularly valuable when monitoring high-speed machinery where vibration frequencies can approach the resonant point of standard transducers.

Where Can You Use the 190501-00-00-00?

The 190501-00-00-00 is suitable for a wide range of rotating equipment, including pumps, fans, compressors, and motors. Its robust design and wide frequency response make it ideal for predictive maintenance programs. For example, in a chemical plant, the transducer can be mounted on a critical pump to monitor bearing wear. The high sensitivity allows early detection of small changes in vibration, giving maintenance teams time to plan repairs without disrupting production.

Moreover, the transducer's internal electronics are isolated from the case, reducing the risk of ground loops. This isolation improves signal integrity, especially in electrically noisy environments. The 190501-00-00-00 also offers a maximum cable length of 305 meters (1,000 ft.) when using the specified cable (part number 02173006), providing flexibility in installation layouts.

Installation and Setup: Getting the Most from Your Transducer

Proper installation is crucial for accurate vibration measurement. The 190501-00-00-00 comes with a mounting hardware option of "No stud" (option 00), meaning you will need to provide a suitable mounting stud or adhesive mount. The mounting surface should be clean and flat, with a diameter of 33 mm (1.3 in). The transducer height is 82 mm (3.2 in), and it can be mounted in any orientation.

When mounting, apply the recommended mounting torque of 4.5 N-m ± 0.6 N-m (40 in–lbf ± 5 in-lbf). This ensures a secure connection without damaging the transducer. The connector is a 2-pin 316L stainless steel MIL-C-5015 type, located on top. Ensure that the mating connector is properly seated and locked to prevent moisture ingress.

For wiring, note the polarity: Pin A goes positive with respect to Pin B when velocity is from base to top of the transducer. This is important for maintaining consistent phase readings across multiple sensors.

Routine Maintenance and Long-Term Reliability

The 190501-00-00-00 is designed for long service life with minimal maintenance. However, regular inspection is recommended to ensure optimal performance. Periodically check the mounting integrity and the condition of the cable and connector. Look for signs of corrosion or damage, especially in harsh environments.

Because the transducer is sealed and has no moving parts, there are no wear items to replace. The 316L stainless steel case provides excellent corrosion resistance, making it suitable for offshore or chemical applications. To maintain accuracy, verify the transducer's sensitivity periodically using a known vibration source, following the manufacturer's guidelines.

Compatibility and Integration

The 190501-00-00-00 is a passive velocity transducer that outputs an AC voltage proportional to vibration velocity. It can be connected to any monitoring system that accepts a standard velocity transducer input. This includes Bently Nevada rack-based monitors and portable data collectors. The output bias voltage of 10.1 Vdc is typical for Bently Nevada transducers, ensuring compatibility with their signal conditioning modules.

For installations requiring intrinsic safety, note that this specific model (option 00) has no agency approvals. If you need intrinsically safe versions, consider models with agency approval options 01 through 04, which carry Ex ia IIC T4 and AEx ia IIC T4 certifications. Always verify the approval rating required for your hazardous area classification.
