One standout feature is the Mounted Resonant Frequency of 9 kHz minimum (stud mounted). This high resonant frequency minimizes interference from structural resonances, ensuring accurate readings in the operating range.

Applications and Use Cases

The 190501-08-00-00 is ideal for monitoring vibration on pumps, motors, fans, and other rotating machinery. Its frequency response covers typical machine speeds, making it suitable for both low-speed and high-speed equipment. For example, in a paper mill, this transducer can detect imbalance or bearing wear early, preventing costly downtime. Additionally, its rugged construction allows installation in harsh environments, such as offshore platforms or chemical plants.

Installation and Setup

Proper installation is crucial for accurate vibration measurement. The 190501-08-00-00 features a plate stud mounting option (3/8-in 24 to 1/2-in 20). Ensure the mounting surface is clean and flat. Apply the specified mounting torque of 4.5 N-m ± 0.6 N-m to secure the transducer. The transducer can be mounted in any orientation, offering flexibility in tight spaces. Use the MIL-C-5015 connection interface for reliable electrical connectivity.

Maintenance and Reliability

Regular inspection of the transducer and its mounting is recommended to ensure long-term reliability. Check for any signs of physical damage or corrosion. Verify that the mounting torque remains within specification. The 316L stainless steel case provides excellent resistance to corrosive environments. With proper care, the 190501-08-00-00 delivers consistent performance over many years, reducing total cost of ownership.

Compatibility and Integration

The 190501-08-00-00 is designed to work with Bently Nevada monitoring systems. Its output bias voltage of 10.1 Vdc ± 1.0 Vdc (Pin A referenced to Pin B) is compatible with standard data acquisition equipment. The transducer can be connected via cable (part number 02173006) up to 305 meters (1,000 ft) without signal degradation. This allows flexible placement of monitoring electronics away from the machine.

Troubleshooting and Common Issues

If the transducer output is erratic, check the cable connection and grounding. The internal electronics are isolated from the case, so ensure proper grounding per the installation drawing. If readings are consistently low, verify that the mounting surface is rigid and free from resonance. For detailed diagnostics, refer to the official Bently Nevada documentation or contact Petro Auto Tech for support.
