190501-01-00-CN | Bently Nevada 100 mV/in/s Velocity Transducer

Introduction to the Bently Nevada 190501-01-00-CN

When machine vibration threatens uptime, the 190501-01-00-CN from Bently Nevada provides accurate, repeatable measurements. This Velomitor CT velocity transducer is engineered for industrial rotating equipment. It converts mechanical velocity into an electrical signal. That signal helps you detect imbalance, misalignment, and bearing wear early.

With a sensitivity of 3.94 mV/mm/s (100 mV/in/s) ±5%, the transducer delivers consistent output. Its frequency response spans 3.0 Hz to 900 Hz (180 to 54,000 cpm) within ±1.0 dB. This range covers most common machinery vibration frequencies. The 190501-01-00-CN is a dependable choice for condition monitoring.

These specs ensure accurate vibration data even in demanding environments. The 190501-01-00-CN is built to perform.

Environmental Durability

Industrial environments can be harsh. The 190501-01-00-CN is designed to withstand them. Its operating temperature range is -40°C to +85°C (-40°F to +185°F). Storage temperature extends to -40°C to +100°C (-40°F to +212°F). It can handle shock up to 5000 g pk. Humidity limits are 100% condensing, non-submerged. Magnetic field susceptibility is <0.0068 mm/s/gauss (0.268 mil/s/gauss) @ 50 gauss, 50-60 Hz. This robustness reduces the risk of failure in critical applications.

Mechanical Construction and Mounting

The transducer features a 316L stainless steel case. The connector is a 2-pin 316L stainless steel MIL-C5015, top-mounted. Weight is less than 297 g (10.5 oz). Mounting surface diameter is 33 mm (1.3 in). Height is 82 mm (3.2 in). Mounting torque is 4.5 N-m ± 0.6 N-m (40 in–lbf ± 5 in-lbf). The mounting hardware option is a stud 3/8-in 24 to 3/8-in 24. Polarity is defined: Pin A goes positive with respect to Pin B when velocity is from base to top. Any mounting angle is acceptable.

Applications and Use Cases

The 190501-01-00-CN is ideal for monitoring pumps, motors, fans, and compressors. It provides velocity output that correlates with machine severity. By tracking vibration trends, you can schedule maintenance before failures occur. This proactive approach reduces downtime and repair costs. The transducer's wide frequency response captures both low-speed and high-speed machinery issues.

Installation and Setup

Proper installation is crucial for accurate readings. Mount the transducer on a flat, clean surface. Use the specified mounting torque of 4.5 N-m ± 0.6 N-m. Ensure the stud is fully engaged. Connect the MIL-C-5015 connector securely. For best results, follow the manufacturer's installation drawing. The maximum cable length of 305 meters allows flexible placement of monitoring equipment.

Maintenance and Reliability

Routine inspection ensures long-term performance. Check the mounting integrity periodically. Verify that the cable is not damaged or stressed. The 190501-01-00-CN has no moving parts, so maintenance is minimal. Its stainless steel construction resists corrosion. Regular verification of output bias voltage can confirm proper operation. Follow the manufacturer's manual for detailed procedures.

Compatibility and Integration

The 190501-01-00-CN is compatible with Bently Nevada monitoring systems. It provides a standard velocity signal. This signal can be integrated into existing condition monitoring setups. The MIL-C-5015 connector ensures a secure, reliable connection. For specific compatibility details, refer to the official Bently Nevada documentation.

Troubleshooting Common Issues

If the output signal is absent, check the cable connection and continuity. Verify that the power supply is within the specified range. If readings are erratic, inspect for loose mounting or damaged cable. The output bias voltage should be 10.1 Vdc ± 1.0 Vdc. If it deviates, the transducer may need replacement. Always consult the manufacturer's troubleshooting guide.
