Key Features and Technical Specifications

The 190501-01-00-01 offers a range of specifications that support reliable performance. Each parameter contributes to its cost-effectiveness by minimizing false readings and extending service life.

• Sensitivity: 3.94 mV/mm/s (100 mV/in/s) ±5% ensures accurate velocity measurement for trend analysis.
• Frequency Response: 3.0 Hz to 900 Hz (180 to 54,000 cpm) ±1.0 dB, and 1.5 Hz to 1.0 kHz (90 to 60,000 cpm) ±3.0 dB, covering typical rotating machinery frequencies.
• Output Bias Voltage: 10.1 Vdc ± 1.0 Vdc, Pin A referenced to Pin B, simplifies integration with monitoring systems.
• Dynamic Output Impedance: <400 Ω typical, ensuring signal integrity over long cable runs.
• Broadband: 0.229 mm/s (0.009 in/s) pk, providing low noise floor for precise measurements.
• Base Strain Sensitivity: 0.43 mm/s/μstrain (0.017 in/s/μstrain), minimizing errors from mounting stress.
• Maximum Cable Length: 305 metres (1,000 ft.) of cable (part number 02173006) with no degradation of signal, offering installation flexibility.
• Operating Temperature: -40°C to +85°C (-40°F to +185°F), suitable for harsh environments.
• Shock Limit: 5000 g pk, maximum, ensuring robustness in high-impact conditions.
• Case Material: 316L stainless steel, providing corrosion resistance and long-term durability.

These specs translate to lower total cost of ownership. The wide frequency response reduces the need for multiple sensors, while the stainless steel case extends replacement intervals.

Applications and Use Cases

The 190501-01-00-01 is ideal for vibration monitoring on rotating equipment such as pumps, fans, and motors. In these applications, early detection of imbalance or bearing wear prevents costly failures. For example, a plant using this transducer can schedule maintenance based on actual condition, avoiding both unnecessary downtime and catastrophic breakdowns. Its rugged design also suits outdoor or washdown areas where moisture and temperature extremes are common.

Installation and Setup

Proper installation is key to maximizing the transducer's performance and your return on investment. The 190501-01-00-01 features a stud mounting option (3/8-in 24 to 3/8-in 24) for secure attachment. Mounting torque should be 4.5 N-m ± 0.6 N-m (40 in–lbf ± 5 in-lbf) to ensure accurate readings. The MIL-C-5015 connection interface simplifies wiring, and the transducer can be oriented in any direction, offering flexibility in tight spaces. Always follow the manufacturer's manual for detailed installation steps.

Maintenance and Reliability

Routine inspection of the transducer and its mounting is essential for sustained accuracy. Because the internal electronics are isolated from the case, the risk of ground loops is reduced, enhancing reliability. The 100% condensing humidity limit means the unit can withstand wet environments without failure, reducing maintenance frequency. By investing in a durable transducer like this, you minimize replacement costs and avoid production interruptions.

Compatibility and Integration

The 190501-01-00-01 is designed to work with Bently Nevada monitoring systems, ensuring seamless data acquisition. Its output bias voltage and low impedance make it compatible with standard vibration monitoring modules. For new installations, verify compatibility with your existing system to avoid integration costs. The transducer's long cable capability also allows placement away from the machine, simplifying routing and reducing installation labor.
