With its compact design and rugged construction, this transducer provides precise velocity readings that help operators detect mechanical faults early, reducing unplanned downtime and maintenance costs.

This transducer is part of the trusted Bently Nevada family, known for its high-quality monitoring solutions. The 190501-10-00-CN is engineered for continuous operation in harsh environments, offering a wide operating temperature range and excellent resistance to shock and humidity. Whether used in rotating machinery, turbines, or compressors, this transducer delivers the data needed to keep operations running smoothly.

Key Features and Technical Specifications

The 190501-10-00-CN offers a range of features that make it a versatile choice for vibration monitoring. Below are the key specifications extracted from the official datasheet:

• 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 temperature 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

These specifications highlight the transducer's ability to provide accurate and reliable vibration data across a broad frequency range. The low dynamic output impedance ensures signal integrity over long cable runs, making it suitable for installations where the monitoring system is located far from the machine.

Applications and Use Cases

The 190501-10-00-CN is ideal for a variety of industrial applications where vibration monitoring is critical. It is commonly used in:

• Rotating machinery such as pumps, motors, and fans
• Turbines and compressors in power generation and oil & gas facilities
• Paper mills, steel plants, and other heavy industrial processes
• Condition monitoring systems for predictive maintenance programs

Because the transducer is designed to operate in temperatures from -40°C to +85°C and can withstand shock up to 5000 g pk, it performs reliably in demanding environments. Its 316L stainless steel case resists corrosion, making it suitable for offshore and chemical processing applications.

Installation and Setup

Proper installation is key to obtaining accurate vibration 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. This allows for flexible mounting on various machine surfaces. The mounting torque should be 4.5 N-m ± 0.6 N-m (40 in-lbf ± 5 in-lbf) to ensure a secure fit without damaging the transducer.

The transducer uses a MIL-C-5015 connection interface, which provides a robust and reliable electrical connection. It can be mounted in any orientation, and the polarity is defined: Pin A goes positive with respect to Pin B when velocity is from base to top. This simplifies wiring and ensures consistent signal interpretation.

For installations requiring long cable runs, the transducer supports up to 305 meters of cable without signal degradation, provided the recommended cable part number is used. This flexibility makes it easier to position the monitoring equipment in a safe and accessible location.

Maintenance and Reliability

The 190501-10-00-CN is designed for long-term reliability with minimal maintenance. Its internal electronics are isolated from the case, reducing the risk of ground loops and electrical interference. The 316L stainless steel construction resists corrosion, and the sealed design protects against humidity and condensation.

To ensure continued accuracy, periodic inspection is recommended. Verify that the mounting stud remains tight and that the connector is clean and free from moisture. Following the manufacturer's guidelines for periodic checks will help maintain optimal performance over the transducer's service life.

Because the transducer has no moving parts, it is not subject to wear in the same way as mechanical sensors. This contributes to lower lifecycle costs and reduced downtime for maintenance.

Compatibility and Integration

The 190501-10-00-CN is designed to work with Bently Nevada monitoring systems and other compatible vibration monitoring equipment. Its standard analog output (sensitivity of 100 mV/in/s) makes it easy to integrate into existing data acquisition systems. The transducer's frequency response covers a wide range, making it suitable for both low-speed and high-speed machinery.

For users upgrading from older velocity transducers, the 190501-10-00-CN offers a drop-in replacement with improved performance and reliability. Its compact size and versatile mounting options simplify retrofits.

Troubleshooting and Common Issues

If the transducer does not provide a signal, check the following:

• Verify that the connector is properly seated and the pins are not damaged.
• Ensure the cable is not cut or pinched, and that the maximum cable length is not exceeded.
• Check the output bias voltage at Pin A relative to Pin B; it should be approximately 10.1 Vdc.
• Confirm that the mounting stud is tight and the transducer is securely attached to the machine.

If issues persist, consult the Bently Nevada documentation or contact Petro Auto Tech for technical support.
