Key Features and Technical Specifications

The 190501-02-00-00 offers a robust set of specifications designed for accurate vibration measurement. Below are the critical parameters:

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

One standout feature is the broad frequency response. It captures both low-speed and high-speed machine vibrations, making it versatile across rotating equipment. Additionally, the low base strain sensitivity minimizes errors from mounting surface flex, ensuring accurate readings.

Applications and Use Cases

The 190501-02-00-00 excels in industries where machinery health is critical. Common applications include:

• Rotating equipment such as motors, generators, and compressors
• Pumps and fans in HVAC, water treatment, and process plants
• Turbines and gearboxes in power generation
• Paper mills, steel mills, and other heavy manufacturing

Because the transducer is hermetically sealed and rated for 100% condensing humidity, it suits outdoor and washdown environments. Moreover, its wide operating temperature range of -40°C to +85°C allows deployment in extreme climates. Consequently, you can rely on consistent performance regardless of location.

Installation and Mounting

Proper installation is essential for accurate vibration data. The 190501-02-00-00 features a stud mounting option (3/8-in 24 to 1/2-in 20) for secure attachment. Follow these guidelines:

• Prepare a clean, flat mounting surface to ensure full contact.
• Apply the recommended mounting torque of 4.5 N-m ± 0.6 N-m (40 in-lbf ± 5 in-lbf).
• Orient the transducer in any direction; it is not position-sensitive.
• Use the specified cable (part number 02173006) for optimal signal integrity.
• Verify the polarity: Pin A goes positive with respect to Pin B when velocity is from base to top.

Additionally, the transducer can be mounted in any orientation, simplifying installation in tight spaces. Always consult the Bently Nevada manual for detailed wiring diagrams and safety instructions.

Maintenance and Reliability

Routine maintenance ensures long-term accuracy. Because the 190501-02-00-00 has no moving parts, it requires minimal upkeep. However, periodic inspection is recommended:

• Check the mounting stud for tightness and corrosion.
• Inspect the connector and cable for damage or wear.
• Verify the output bias voltage (10.1 Vdc ± 1.0 Vdc) to confirm proper operation.
• Clean the exterior with a soft cloth; avoid harsh solvents.

By following these simple steps, you extend the transducer's service life and maintain measurement integrity. This reliability translates into lower total cost of ownership, as fewer replacements and recalibrations are needed.

Compatibility and Integration

The 190501-02-00-00 is designed to work seamlessly with Bently Nevada monitoring systems. Its MIL-C-5015 connection interface ensures compatibility with standard industrial connectors. The transducer outputs a velocity signal that can be integrated into existing condition monitoring networks.

For new installations, pair the transducer with Bently Nevada's compatible cables and junction boxes. The maximum cable length of 305 metres allows flexible placement of monitoring equipment. Always verify system compatibility with your specific monitor or data acquisition unit.

Environmental Durability

Industrial environments can be harsh, but the 190501-02-00-00 is built to endure. Its 316L stainless steel case resists corrosion, and the internal electronics are isolated from the case to prevent ground loops. The transducer handles:

• Operating temperature: -40°C to +85°C (-40°F to +185°F)
• Storage temperature: -40°C to +100°C (-40°F to +212°F)
• Shock limit: 5000 g pk maximum
• Humidity: 100% condensing, non-submerged
• Magnetic field susceptibility: <0.0068 mm/s/gauss (0.268 mil/s/gauss) @ 50 gauss, 50-60 Hz

This ruggedness ensures dependable operation in demanding applications, from offshore platforms to desert installations.
