• 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 the 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: 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 show that the 190501-01-00-00 is built for accuracy and stability. The high sensitivity and wide frequency range make it ideal for capturing subtle vibrations. Moreover, the low output impedance ensures signal integrity even over long cable runs.

Environmental Durability and Mechanical Design

Industrial environments can be harsh, but the 190501-01-00-00 is designed to withstand them. Its operating temperature range spans from -40°C to +85°C (-40°F to +185°F), and storage temperature extends to -40°C to +100°C (-40°F to +212°F). The transducer can handle shock up to 5000 g pk and operates in 100% condensing humidity (non-submerged). Magnetic field susceptibility is less than 0.0068 mm/s/gauss (0.268 mil/s/gauss) at 50 gauss, 50-60 Hz.

Mechanically, the unit weighs less than 297 g (10.5 oz) and features a 316L stainless steel case and connector. The mounting surface is 33 mm in diameter, and the height is 82 mm. Mounting torque is specified at 4.5 N-m ± 0.6 N-m (40 in-lbf ± 5 in-lbf). The transducer can be mounted in any orientation, and polarity is defined: Pin A goes positive with respect to Pin B when velocity is from base to top.

These robust characteristics ensure reliable operation in challenging conditions. The stainless steel construction resists corrosion, and the sealed design protects internal components. As a result, you can count on long-term performance with minimal maintenance.

Applications and Use Cases

The 190501-01-00-00 is suitable for vibration monitoring on pumps, motors, fans, compressors, and other rotating equipment. Its frequency response covers typical machine speeds, making it versatile for many industries. For example, in a petrochemical plant, you can install this transducer on critical pumps to detect bearing wear or imbalance. By doing so, you gain early warnings that help prevent unplanned shutdowns.

Furthermore, the transducer's ability to handle long cable runs (up to 305 meters) allows flexible placement of monitoring electronics. This feature is particularly useful in large facilities where sensors are far from control rooms. Additionally, the internal grounding isolation reduces noise interference, ensuring clean signals for your monitoring system.

Installation and Setup

Proper installation is crucial for accurate measurements. The 190501-01-00-00 uses a stud mounting option (3/8-in 24 to 3/8-in 24) and a MIL-C-5015 connection interface. Before mounting, ensure the mounting surface is clean and flat. Apply the recommended torque of 4.5 N-m ± 0.6 N-m (40 in-lbf ± 5 in-lbf) to secure the stud. Avoid over-tightening, as this could damage the transducer.

For wiring, connect Pin A and Pin B as per the polarity specification. The output bias voltage is 10.1 Vdc ± 1.0 Vdc, which you can verify during commissioning. If you are using a cable longer than 305 meters, consult the manufacturer for guidance. Always follow the installation drawing (e.g., 167536 for intrinsically safe versions) to meet safety requirements.

Maintenance and Reliability

To maintain optimal performance, inspect the transducer periodically. Check the mounting integrity and ensure the connector is secure. Since the unit is sealed, there are no user-serviceable parts. However, you should verify that the cable is not damaged and that the signal remains stable.

The 190501-01-00-00 is designed for long service life, but environmental factors like extreme temperatures or vibration can affect it. Regular calibration checks are recommended to confirm sensitivity remains within ±5%. If you notice any drift, contact Bently Nevada or Petro Auto Tech for support.

Compatibility and Integration

This transducer works with Bently Nevada monitoring systems and other data acquisition equipment that accepts velocity inputs. The standard MIL-C-5015 connector simplifies integration. Moreover, the output signal is compatible with most vibration monitors. For specific compatibility details, refer to the product datasheet or consult with Petro Auto Tech.
