Introduction to the Bently Nevada 190501-01-00-00

When rotating machinery vibration threatens uptime, the 190501-01-00-00 from Bently Nevada provides the precise measurement you need. This Velomitor CT velocity transducer is engineered for industrial condition monitoring. It converts mechanical velocity into an electrical signal for analysis. The transducer features a sensitivity of 3.94 mV/mm/s (100 mV/in/s) with ±5% tolerance. This ensures accurate readings across your critical assets.

As a consulting engineer, you need dependable data. The 190501-01-00-00 delivers that reliability. Its internal electronics are isolated from the case, reducing ground loop risks. The 316L stainless steel construction withstands harsh environments. This transducer is a solid choice for permanent installation on pumps, motors, and fans.

Key Features and Technical Specifications

The 190501-01-00-00 offers a frequency response from 3.0 Hz to 900 Hz (180 to 54,000 cpm) with ±1.0 dB. An extended range of 1.5 Hz to 1.0 kHz (90 to 60,000 cpm) is available at ±3.0 dB. This broad bandwidth captures both slow-speed and high-speed vibration events. The output bias voltage is 10.1 Vdc ± 1.0 Vdc, referenced from Pin A to Pin B. Dynamic output impedance is less than 400 Ω typical.

These specifications make the 190501-01-00-00 suitable for machinery protection. The transducer operates over a temperature range of -40°C to +85°C (-40°F to +185°F). It can withstand shock up to 5000 g pk. Humidity limits reach 100% condensing, non-submerged. This rugged design ensures long service life in demanding industrial settings.

Applications and Use Cases

In petrochemical plants, the 190501-01-00-00 monitors critical pumps and compressors. Its frequency response covers typical machine speeds. For example, a 3600 RPM motor produces a fundamental frequency of 60 Hz. This transducer accurately captures that vibration. Additionally, it detects higher harmonics up to 900 Hz. This helps identify bearing faults or misalignment early.

In power generation, the transducer monitors turbine bearings. The 3.0 Hz lower limit allows detection of low-speed shaft vibrations. This is crucial for hydro turbines or large fans. The transducer's transverse response is less than 5% of axial sensitivity. This ensures measurements focus on the intended axis. Consequently, you get cleaner data for diagnostics.

Installation and Setup

Mounting the 190501-01-00-00 is straightforward. The stud mounting option uses a 3/8-in 24 thread. Apply the specified mounting torque of 4.5 N-m ± 0.6 N-m (40 in-lbf ± 5 in-lbf). This ensures proper coupling and accurate readings. The transducer can be mounted in any orientation. This flexibility simplifies installation on existing machinery.

The connection interface is a MIL-C-5015 2-pin connector. This provides a secure, weatherproof connection. Maximum cable length is 305 metres (1,000 ft.) using cable part number 02173006. This allows remote placement of monitoring electronics. No signal degradation occurs up to this length. For best results, route cables away from high-voltage sources.

Maintenance and Reliability

Regular inspection of the 190501-01-00-00 ensures consistent performance. Check the mounting stud for tightness periodically. Verify the connector is clean and free from corrosion. The 316L stainless steel case resists corrosion. This reduces maintenance frequency in harsh environments. The internal electronics are isolated from the case, protecting against ground loops.

Temperature sensitivity varies from -8% to +5% over the operating range. This is typical for piezoelectric sensors. Therefore, calibration checks are recommended annually. The transducer's amplitude linearity is ±2% to 63.5 mm/s pk (2.5 in/s pk). This ensures accurate readings across its range. With proper care, the transducer provides years of reliable service.

Compatibility and Integration

The 190501-01-00-00 integrates with Bently Nevada monitoring systems. It connects to vibration monitors and diagnostic equipment. The output is a standard velocity signal. This makes it compatible with most data acquisition systems. The MIL-C-5015 connector is industry standard. Hence, replacement is simple.

For new installations, pair this transducer with a compatible monitor. The 10.1 Vdc bias voltage is typical for piezoelectric sensors. Therefore, most Bently Nevada monitors will accept this signal. Always verify compatibility with your specific monitor model. Contact Petro Auto Tech for assistance.
