Technical Specifications Breakdown
The 190501-19-00-CN offers a sensitivity of 3.94 mV/mm/s, ensuring accurate velocity measurement across a broad frequency range. Its frequency response extends from 3.0 Hz to 900 Hz within ±1.0 dB, and up to 1.0 kHz within ±3.0 dB, making it suitable for low- to medium-speed machinery. The output bias voltage of 10.1 Vdc ± 1.0 Vdc provides a stable baseline for signal processing. With a mounted resonant frequency of 9 kHz minimum, the transducer avoids interference from structural resonances. The rugged 316L stainless steel case and MIL-C-5015 connector ensure durability in demanding industrial settings.
Industry Applications
The Bently Nevada 190501-19-00-CN is ideal for vibration monitoring on pumps, fans, compressors, and turbines. In a typical application, plant engineers mount the transducer on bearing housings to detect imbalance, misalignment, or bearing wear. For example, in a petrochemical facility, the 190501-19-00-CN provides continuous data that triggers alarms before catastrophic failure, reducing unplanned downtime. Its wide operating temperature range and 100% condensing humidity rating make it suitable for outdoor and washdown environments.
Installation & Setup Guidance
Mount the 190501-19-00-CN using the provided 3/8-in 24 to 1/4-in 18 NPT adapter. Ensure the mounting surface is flat and clean. Apply the recommended mounting torque of 4.5 N-m ± 0.6 N-m (40 in-lbf ± 5 in-lbf). The transducer can be oriented in any direction. Connect the 2-pin MIL-C-5015 connector, observing polarity: Pin A goes positive with respect to Pin B when velocity is from base to top. Keep cable length within 305 metres (1,000 ft) to avoid signal degradation.
Maintenance & Reliability
The 190501-19-00-CN requires minimal maintenance due to its solid-state design. Periodically inspect the mounting integrity and connector condition. Verify output bias voltage at the monitor to ensure the transducer is functioning correctly. The internal electronics are isolated from the case, reducing ground loop issues. With a shock limit of 5000 g pk, the transducer withstands severe transient events. Regular calibration checks every 12 months are recommended to maintain accuracy.
Selection Guide & Purchasing Advice
Before ordering, confirm your system's input requirements and cable connector type. The 190501-19-00-CN uses a MIL-C-5015 connection interface—verify compatibility with your extension cable.
