Its high sensitivity and wide frequency response help detect early signs of bearing wear, imbalance, or misalignment, allowing you to schedule repairs before costly failures occur.

Key Features and Technical Specifications

The 190501-00-00-CN is built to deliver accurate data in demanding environments. Below are its core specifications, each contributing to long-term reliability and cost-effective operation.

• Sensitivity: 3.94 mV/mm/s (100 mV/in/s) ±5% – ensures consistent, repeatable measurements.
• 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 – captures a broad range of vibration frequencies.
• Output Bias Voltage: 10.1 Vdc ± 1.0 Vdc, Pin A referenced to Pin B – provides a stable signal for monitoring systems.
• Dynamic Output Impedance: <400 Ω typical – allows long cable runs without signal degradation.
• Broadband Noise: 0.229 mm/s (0.009 in/s) pk – ensures low noise for accurate readings.
• Base Strain Sensitivity: 0.43 mm/s/μstrain (0.017 in/s/μstrain) – minimizes errors from mounting stress.
• Maximum Cable Length: 305 metres (1,000 ft.) of cable (part number 02173006) – flexible installation options.
• Operating Temperature: -40°C to +85°C (-40°F to +185°F) – suitable for harsh industrial environments.
• Shock Limit: 5000 g pk, maximum – withstands severe transient impacts.
• Humidity Limit: 100% condensing, non-submerged – reliable in wet conditions.
• Magnetic Field Susceptibility: <0.0068 mm/s/gauss (0.268 mil/s/gauss) @ 50 gauss, 50-60Hz – immune to common electromagnetic interference.
• Case Material: 316L stainless steel – corrosion-resistant for long service life.
• Connector: 2-pin 316L stainless steel MIL-C5015, top – rugged and secure.
• Mounting Torque: 4.5 N-m ± 0.6 N-m (40 in–lbf ± 5 in-lbf) – ensures proper installation.
• Weight: <297 g (10.5 oz.), typical – lightweight and easy to handle.

These specifications translate directly to reduced maintenance costs. The wide frequency response and high sensitivity mean you can detect problems earlier, avoiding expensive emergency repairs. The robust construction and environmental ratings extend the transducer's lifespan, lowering replacement frequency.

Applications and Use Cases

The 190501-00-00-CN is ideal for monitoring pumps, motors, fans, compressors, and other rotating machinery. In a typical plant, installing these transducers on critical assets provides continuous vibration data that feeds into a condition monitoring system. For example, a paper mill might use them on dryer rolls to detect bearing degradation before it causes a web break. Similarly, a petrochemical facility could monitor cooling tower fans to prevent unplanned shutdowns. By integrating this transducer into your predictive maintenance strategy, you can shift from reactive repairs to planned interventions, significantly reducing downtime costs.

Installation and Setup

Proper installation is key to achieving accurate measurements. The 190501-00-00-CN features a no-stud mounting option (option 00), which simplifies mounting on flat surfaces. Use the specified mounting torque of 4.5 N-m ± 0.6 N-m to avoid over-tightening, which could affect sensitivity. The transducer can be mounted in any orientation, offering flexibility in tight spaces. For best results, ensure the mounting surface is clean and flat. The MIL-C-5015 connection interface provides a secure, weatherproof connection. When routing cables, avoid sharp bends and potential abrasion points to protect the signal integrity.

Maintenance and Reliability

Routine maintenance of the 190501-00-00-CN is minimal, but periodic checks are recommended. Inspect the transducer and cable for physical damage, especially in high-vibration areas. Verify that the mounting bolt remains tight to the specified torque. Because the internal electronics are isolated from the case, there is no electrical path to ground, reducing the risk of ground loops. The 316L stainless steel case resists corrosion, even in humid or chemical-laden atmospheres. By following a simple inspection schedule, you can ensure the transducer continues to provide reliable data for years, maximizing your return on investment.

Compatibility and Integration

The 190501-00-00-CN is designed to work seamlessly with Bently Nevada monitoring systems and other industrial vibration monitoring equipment. Its standard 10.1 Vdc bias voltage and low output impedance make it compatible with most data acquisition systems. The MIL-C-5015 connector is a common interface in industrial settings, simplifying replacement of older transducers. For new installations, the transducer's any-orientation mounting and long cable length capability (up to 305 meters) offer design flexibility. Always consult the official Bently Nevada documentation for detailed integration guidelines.
