Key Features and Technical Specifications

The 190501-02-00-00 offers several distinctive features that enhance its performance in vibration monitoring applications:

• 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 the 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.) of cable (part number 02173006) with no degradation of signal.

These specs highlight the transducer's ability to deliver accurate, repeatable measurements in demanding settings. The low base strain sensitivity and high resonant frequency make it suitable for high-speed machinery.

Applications and Use Cases

The 190501-02-00-00 is ideal for monitoring vibration on pumps, motors, fans, and other rotating equipment. Its wide frequency response captures both low-speed and high-speed vibration signatures, enabling early detection of bearing wear, unbalance, and misalignment. In addition, the transducer's robust construction allows it to perform reliably in extreme temperatures and humid conditions, reducing the risk of unexpected downtime.

For example, in a chemical processing plant, the transducer can be mounted on critical pumps to provide continuous data for condition monitoring. This data supports proactive maintenance, ultimately lowering operational costs and extending equipment life.

Installation and Setup

Proper installation is essential for optimal performance. The 190501-02-00-00 features a stud mounting option (3/8-in 24 to 1/2-in 20) and a MIL-C-5015 connection interface. The mounting torque should be 4.5 N-m ± 0.6 N-m (40 in–lbf ± 5 in-lbf). The transducer can be mounted in any orientation, providing flexibility in tight spaces.

For best results, ensure the mounting surface is clean and flat. The transducer's height is 82 mm (3.2 in) and the mounting surface diameter is 33 mm (1.3 in). Use the specified cable (part number 02173006) to maintain signal integrity over long distances.

Maintenance and Reliability

Regular inspection of the 190501-02-00-00 is recommended to ensure continuous accuracy. Check the mounting integrity and cable connections periodically. The transducer is designed for long-term reliability, with a case material of 316L stainless steel that resists corrosion. Its operating temperature range is -40°C to +85°C (-40°F to +185°F), and it can withstand shock up to 5000 g pk.

Because the internal electronics are isolated from the case, the transducer is less susceptible to ground loops, enhancing measurement stability. Following the manufacturer's guidelines for periodic verification will help maintain optimal performance.

Compatibility and Integration

The 190501-02-00-00 is compatible with Bently Nevada monitoring systems and can be integrated into existing vibration monitoring networks. Its output bias voltage of 10.1 Vdc and dynamic output impedance of <400 Ω allow it to interface with standard data acquisition equipment. The MIL-C-5015 connector ensures a secure, reliable connection.

For new installations, the transducer can be paired with Bently Nevada's signal conditioning modules to provide a complete monitoring solution. Always verify compatibility with your specific system before ordering.

Environmental Durability

This transducer is built to withstand harsh environments. It operates in 100% condensing humidity (non-submerged) and has a magnetic field susceptibility of <0.0068 mm/s/gauss (0.268 mil/s/gauss) @ 50 gauss, 50-60 Hz. The storage temperature range is -40°C to +100°C (-40°F to +212°F). These features make it suitable for outdoor and industrial applications.
