Key Features and Technical Specifications

The 190501-02-00-01 is packed with features that enhance its usability and reliability. Below are the core specifications extracted from the datasheet:

• 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
• Broadband Noise: 0.229 mm/s (0.009 in/s) pk
• Base Strain Sensitivity: 0.43 mm/s/μstrain (0.017 in/s/μstrain)
• Operating Temperature: -40°C to +85°C (-40°F to +185°F)
• Shock Limit: 5000 g pk, maximum
• Humidity Limit: 100% condensing, non-submerged
• Case Material: 316L stainless steel
• Mounting Torque: 4.5 N-m ± 0.6 N-m (40 in–lbf ± 5 in-lbf)

One standout feature is the mounted resonant frequency of 9 kHz minimum (stud mounted, except quick disconnect). This high resonant frequency ensures accurate measurement across the operating range without interference from structural resonances. Additionally, the internal electronics are isolated from the case, reducing ground loop issues and improving signal integrity.

Applications and Use Cases

The 190501-02-00-01 is ideal for vibration monitoring on pumps, fans, compressors, and other rotating equipment. Its wide frequency response and high shock tolerance make it suitable for harsh industrial environments. For example, in a petrochemical plant, this transducer can be installed on critical pumps to detect early signs of bearing wear, allowing maintenance teams to schedule repairs before catastrophic failure occurs. Moreover, its ATEX and IECEx certifications permit installation in explosive atmospheres, expanding its applicability to oil and gas facilities.

Installation and Setup

Proper installation is crucial for accurate vibration measurement. The 190501-02-00-01 features a stud mounting option (3/8-in 24 to 1/2-in 20) and a MIL-C-5015 connection interface. Follow these general guidelines:

• Mount the transducer on a flat, clean surface to ensure good mechanical coupling.
• Apply the specified mounting torque of 4.5 N-m ± 0.6 N-m to avoid over-tightening.
• Route cables away from high-temperature sources and moving parts.
• For hazardous area installations, refer to the installation drawing 167536 as required by the agency approvals.

Always consult the Bently Nevada installation manual for detailed instructions specific to your application.

Maintenance and Reliability

Routine maintenance of the 190501-02-00-01 is minimal due to its solid-state design. However, periodic inspection is recommended to verify that the mounting remains secure and the cable is undamaged. The transducer's 316L stainless steel case resists corrosion, and its sealed construction protects against moisture and dust. With a storage temperature range of -40°C to +100°C, it can withstand harsh storage conditions. By incorporating this transducer into a predictive maintenance program, you can reduce unplanned downtime and extend machinery life, delivering long-term cost savings.

Compatibility and Integration

The 190501-02-00-01 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 maximum cable length of 305 meters (1,000 ft.) with part number 02173006 allows flexible placement of monitoring electronics. For seamless setup, verify compatibility with your current monitoring hardware or consult Petro Auto Tech for guidance.

Troubleshooting and Common Issues

If you encounter erratic readings, first check the cable connections and ensure the transducer is securely mounted. Verify that the output bias voltage is within 10.1 Vdc ± 1.0 Vdc. Excessive vibration or shock beyond the 5000 g limit may damage the sensor, so review operating conditions. For persistent issues, refer to the Bently Nevada troubleshooting guide or contact Petro Auto Tech for technical support.
