Key Features & Technical Specifications

The 190501-01-00-01 provides a frequency response of 3.0 Hz to 900 Hz (180 to 54,000 cpm) ±1.0 dB, ensuring accurate readings across a wide range of machine speeds. Its sensitivity of 3.94 mV/mm/s (100 mV/in/s) ±5% delivers consistent output for condition monitoring. The transducer operates from -40°C to +85°C, making it suitable for harsh environments. With a mounted resonant frequency of 9 kHz minimum, it avoids interference from structural resonances. The output bias voltage of 10.1 Vdc ± 1.0 Vdc (Pin A referenced to Pin B) simplifies integration with standard monitoring systems. Its 316L stainless steel case and connector provide excellent corrosion resistance, and the internal electronics are isolated from the case to prevent ground loops.

Installation & Setup

Mounting the 190501-01-00-01 is straightforward with a 3/8-in 24 stud, and the MIL-C-5015 connection interface ensures a secure electrical connection. The recommended mounting torque is 4.5 N-m ± 0.6 N-m (40 in-lbf ± 5 in-lbf), which prevents damage while ensuring proper coupling. The transducer can be mounted in any orientation, offering flexibility in tight spaces. For best results, follow the installation drawing 167536 provided by Bently Nevada, and verify that the mounting surface is clean and flat to achieve accurate measurements.

Maintenance & Reliability

Routine inspection is essential to maintain the reliability of the 190501-01-00-01. Periodically check the mounting integrity and the condition of the cable to prevent signal degradation. The transducer's robust design, including a 316L stainless steel case, withstands harsh environments, reducing the need for frequent replacements. Its humidity limit of 100% condensing (non-submerged) and shock limit of 5000 g pk ensure long-term durability. By following a simple maintenance schedule, you can extend the service life and avoid unexpected downtime.

Compatibility & Integration

The 190501-01-00-01 is designed to work seamlessly with Bently Nevada monitoring systems, providing a 10.1 Vdc bias voltage that matches standard inputs. Its output impedance of less than 400 Ω typical ensures compatibility with most data acquisition units. The maximum cable length of 305 meters (1,000 ft) allows flexible placement of the transducer relative to the monitoring equipment. This integration simplicity reduces installation time and minimizes the risk of signal loss.
