With a sensitivity of 3.94 mV/mm/s (±5%), it captures subtle changes in machinery health, helping you detect issues before they escalate into costly failures.

As a maintenance engineer, you need instruments you can trust. The 190501-01-00-01 is built to deliver consistent performance across demanding conditions, simplifying your predictive maintenance program.

Key Features and Technical Specifications

The 190501-01-00-01 offers a robust set of specifications designed for real-world reliability:

• 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
• Output Bias Voltage: 10.1 Vdc ± 1.0 Vdc, Pin A referenced to Pin B
• Dynamic Output Impedance: <400 Ω typical
• Mounted Resonant Frequency: 9 kHz minimum (stud mounted, except quick disconnect)
• Operating Temperature: -40°C to +85°C (-40°F to +185°F)
• Shock Limit: 5000 g pk, maximum
• Case Material: 316L stainless steel
• Weight: <297 g (10.5 oz.) typical
• Mounting Torque: 4.5 N-m ± 0.6 N-m (40 in–lbf ± 5 in-lbf)

These specs translate to dependable vibration data. The wide frequency response captures both low-speed and high-speed machine dynamics, while the rugged stainless steel case withstands harsh industrial environments.

Real-World Applications

In rotating machinery such as pumps, motors, and fans, the 190501-01-00-01 excels at monitoring casing vibration. Its broad frequency range makes it suitable for variable-speed equipment, where vibration signatures change with operating speed. Furthermore, the transducer's low transverse response (less than 5% of axial sensitivity) ensures accurate axial measurements, reducing false alarms.

For maintenance teams, this means fewer unexpected breakdowns and more efficient condition-based maintenance. By integrating this transducer into your monitoring system, you gain early warning of bearing wear, unbalance, and misalignment—all common failure modes.

Installation and Setup

Proper installation is key to accurate readings. The 190501-01-00-01 features a stud mount (3/8-in 24 to 3/8-in 24) and a MIL-C-5015 connection interface. For best results, mount the transducer on a flat, clean surface. Apply the specified mounting torque of 4.5 N-m ± 0.6 N-m to ensure a secure fit without over-stressing the housing.

Connect the cable per the provided drawing (part number 167536). The transducer can be mounted in any orientation, offering flexibility in tight spaces. Additionally, the internal electronics are isolated from the case, reducing ground loop issues.

Maintenance and Reliability

Routine inspection of the transducer and its cable is essential. Check for physical damage, loose connections, and signs of corrosion. The 316L stainless steel case resists rust, but periodic cleaning with a soft cloth is recommended. Verify the output bias voltage periodically to confirm the electronics are functioning correctly.

Because the 190501-01-00-01 has no moving parts, it requires minimal maintenance. This translates to lower lifecycle costs and less downtime. Its robust design, including a shock limit of 5000 g, ensures it survives harsh events without compromising performance.

Compatibility and Integration

The 190501-01-00-01 is compatible with Bently Nevada monitoring systems that accept velocity transducer inputs. Its standard MIL-C-5015 connector simplifies integration with existing cabling. The maximum cable length of 305 meters (1,000 ft.) allows flexible placement of monitoring electronics away from the machine.

For hazardous area installations, the transducer carries agency approvals including CSA/NRTL/C (Class I, Division 1) and ATEX/IECEx/CSA (Class I, Zone 0/1). This makes it suitable for use in explosive atmospheres, provided it is installed per drawing 167536.
