190501-01-00-00 | Bently Nevada Velomitor CT Velocity Transducer

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

When you need accurate vibration measurement in rotating machinery, the 190501-01-00-00 from Bently Nevada delivers dependable performance. This Velomitor CT Velocity Transducer is engineered for industrial environments where precise velocity sensing is critical. With its robust 316L stainless steel case and MIL-C-5015 connection interface, it is built to withstand harsh conditions.

The transducer provides a sensitivity of 3.94 mV/mm/s (100 mV/in/s) with ±5% tolerance, ensuring consistent output for condition monitoring. Its frequency response spans 3.0 Hz to 900 Hz (±1.0 dB) and extends to 1.5 Hz to 1.0 kHz (±3.0 dB), covering a wide range of vibration frequencies.

One standout feature is the base strain sensitivity of 0.43 mm/s/μstrain, which minimizes errors from mounting surface strain. This is crucial for accurate readings in high-stress installations.

Applications and Use Cases

In industrial settings, the 190501-01-00-00 is ideal for monitoring pumps, motors, fans, and compressors. Its frequency response covers typical machine vibration ranges, making it suitable for predictive maintenance programs. For example, in a petrochemical plant, this transducer can detect early bearing wear, helping to avoid unplanned downtime. Additionally, its internal electronics are isolated from the case, reducing ground loop issues.

Installation and Setup

Proper installation is key to accurate measurements. The transducer mounts via a 3/8-in 24 stud, and you should apply a mounting torque of 4.5 N-m ± 0.6 N-m (40 in-lbf ± 5 in-lbf). Ensure the mounting surface is clean and flat, with a diameter of 33 mm (1.3 in). The transducer can be oriented in any direction, giving you flexibility in tight spaces. For best results, use the recommended cable (part number 02173006) up to 305 meters (1,000 ft) without signal degradation.

Maintenance and Reliability

Regular inspection ensures long-term reliability. Check the mounting integrity periodically, as loose studs can affect readings. The 316L stainless steel case resists corrosion, but verify the connector for moisture ingress, especially in condensing environments. The transducer operates in temperatures from -40°C to +85°C, and storage up to +100°C, so it can handle extreme conditions. By following a simple inspection routine, you extend service life and maintain measurement accuracy.

Compatibility and Integration

The 190501-01-00-00 is designed to work with Bently Nevada monitoring systems. Its MIL-C-5015 connector ensures a secure, standardized interface. The output bias voltage of 10.1 Vdc is compatible with most data acquisition systems. For installations requiring intrinsic safety, note that this specific model (Agency Approval Option 00) has no approvals, so verify your area classification before use.
