This transducer is part of Bently Nevada's trusted family of monitoring solutions, known for their durability and accuracy. With a compact design and robust construction, the 190501-08-00-00 is suitable for a wide range of industrial environments, from power generation to petrochemical processing.

Key Features and Technical Specifications

The 190501-08-00-00 is built to deliver consistent performance under challenging conditions. Its key specifications include:

• 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.
• 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.
• Output Bias Voltage: 10.1 Vdc ± 1.0 Vdc, Pin A referenced to Pin B.
• Dynamic Output Impedance: <400 Ω typical.
• Maximum Cable Length: 305 metres (1,000 ft.) of cable (part number 02173006) with no degradation of signal.

One standout feature is the mounted resonant frequency of 9 kHz minimum, which ensures accurate measurement even in high-frequency vibration environments. This makes the 190501-08-00-00 particularly effective for monitoring high-speed rotating equipment.

Applications and Use Cases

The 190501-08-00-00 is designed for vibration monitoring in critical machinery such as turbines, compressors, pumps, and motors. Its rugged construction and wide operating temperature range make it suitable for both indoor and outdoor installations. For instance, in a petrochemical plant, the transducer can be mounted on a pump to continuously monitor bearing health, providing early warning of wear or misalignment. This proactive approach helps reduce unplanned downtime and maintenance costs.

Installation and Setup

Proper installation is crucial for optimal performance. The 190501-08-00-00 features a plate stud mounting option (3/8-in 24 to 1/2-in 20) and a MIL-C-5015 connection interface. The transducer can be mounted in any orientation, offering flexibility in tight spaces. Recommended mounting torque is 4.5 N-m ± 0.6 N-m (40 in–lbf ± 5 in-lbf). Ensure the mounting surface is clean and flat to achieve accurate readings. For detailed wiring instructions, refer to the official Bently Nevada documentation.

Maintenance and Reliability

Routine maintenance of the 190501-08-00-00 is minimal, but periodic inspection is recommended to verify its operation and mounting integrity. The transducer is built to withstand harsh conditions, including 100% condensing humidity and magnetic fields up to 50 gauss. Its internal electronics are isolated from the case, reducing the risk of ground loops. Regular checks of the cable and connector can prevent signal degradation over time.

Compatibility and Integration

The 190501-08-00-00 is compatible with Bently Nevada monitoring systems that accept velocity transducer inputs. Its standard MIL-C-5015 connector ensures easy integration with existing cabling. The transducer's output can be connected to a variety of data acquisition systems or vibration monitors for real-time analysis.

Troubleshooting and Common Issues

If the transducer fails to provide a signal, check the cable connection and ensure the mounting is secure. Verify that the output bias voltage is within the specified range (10.1 Vdc ± 1.0 Vdc). If readings are erratic, inspect for loose mounting or cable damage. For persistent issues, consult the official Bently Nevada manual or contact Petro Auto Tech for technical support.
