As a maintenance engineer, you need sensors that perform consistently. The 190501-00-00-CN delivers a frequency response of 3.0 Hz to 900 Hz (180 to 54,000 cpm) ±1.0 dB, ensuring you see the full picture of machine health. Its robust design and country-specific approval option (CN) make it suitable for global installations.

Key Features and Technical Specifications

The 190501-00-00-CN is built to withstand harsh conditions while providing precise measurements. Here are the critical specs 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
• Temperature Sensitivity: -8% to +5% typical over operating range
• 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, except quick disconnect)
• 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)
• Grounding: Internal electronics isolated from case
• Maximum Cable Length: 305 metres (1,000 ft.) with part number 02173006

One standout feature is the output bias voltage of 10.1 Vdc ± 1.0 Vdc, which simplifies integration with standard monitoring systems. This consistency reduces setup time and ensures accurate readings from day one.

Real-World Applications and Reliability

The 190501-00-00-CN excels in rotating machinery monitoring, including pumps, fans, compressors, and turbines. Its wide frequency response captures both low-speed and high-speed vibrations, making it versatile across industries. For maintenance teams, this means fewer false alarms and more actionable data.

Moreover, the transducer's 316L stainless steel case and MIL-C-5015 connection interface ensure durability in corrosive environments. The internal electronics are isolated from the case, reducing ground loop issues that can plague other sensors. Consequently, you get cleaner signals and less downtime for troubleshooting.

Installation and Setup Guidance

Proper installation is key to maximizing the 190501-00-00-CN's performance. The unit comes with a no stud mounting option (option 00), so you'll need to provide a suitable mounting method. The mounting surface is 33 mm diameter (1.3 in), and the height is 82 mm (3.2 in).

When mounting, apply a torque of 4.5 N-m ± 0.6 N-m (40 in–lbf ± 5 in-lbf) to ensure a secure fit without damaging the transducer. The sensor can be mounted in any orientation, offering flexibility in tight spaces. For best results, follow the manufacturer's guidelines and use the recommended cable (part number 02173006) to maintain signal integrity over long runs.

Maintenance and Long-Term Reliability

Routine maintenance of the 190501-00-00-CN is straightforward. Periodically inspect the mounting and cable connections for wear or corrosion. The transducer operates in temperatures from -40°C to +85°C (-40°F to +185°F) and can withstand 100% condensing humidity, making it suitable for most industrial settings.

Additionally, the shock limit of 5000 g pk ensures the sensor survives accidental impacts. With proper care, this transducer provides years of reliable service, reducing total cost of ownership. For any issues, consult the official Bently Nevada documentation or contact Petro Auto Tech for support.

Compatibility and Integration

The 190501-00-00-CN is designed to work with Bently Nevada monitoring systems, but its standard 100 mV/in/s output makes it compatible with many third-party vibration monitors. The MIL-C-5015 connector ensures a secure, industry-standard connection. Always verify compatibility with your existing equipment before installation.
