190501-10-00-CN | Bently Nevada 100 mV/in/s Velocity Transducer

Introduction to the Bently Nevada 190501-10-00-CN

When machinery vibration threatens uptime, the 190501-10-00-CN provides precise velocity measurement. This Bently Nevada Velomitor CT velocity transducer is engineered for continuous monitoring in demanding industrial environments. Its robust design and high sensitivity make it a dependable choice for predictive maintenance programs.

Key Features and Technical Specifications

The 190501-10-00-CN offers performance that supports early fault detection. Below are its core specifications:

• Sensitivity: 3.94 mV/mm/s (100 mV/in/s) ±5%
• Frequency response: 3.0 Hz to 900 Hz (180 to 54,000 cpm) ±1.0 dB
• Extended response: 1.5 Hz to 1.0 kHz (90 to 60,000 cpm) ±3.0 dB
• Output bias voltage: 10.1 Vdc ± 1.0 Vdc (Pin A referenced to Pin B)
• Dynamic output impedance: <400 Ω typical
• Mounted resonant frequency: 9 kHz minimum (stud mounted)
• Operating temperature: -40°C to +85°C
• Shock limit: 5000 g pk maximum
• Case material: 316L stainless steel
• Weight: <297 g (10.5 oz.) typical

These specs ensure accurate vibration data even in harsh conditions. The transducer's internal electronics are isolated from the case, reducing ground loop issues.

Applications and Use Cases

The 190501-10-00-CN is ideal for rotating machinery such as pumps, motors, fans, and turbines. Its frequency range covers common machine vibration signatures, enabling early detection of imbalance, misalignment, and bearing wear. Because it is a velocity transducer, it provides direct velocity output, which is often preferred for machinery protection and diagnostics.

Furthermore, its compact size and any-orientation mounting angle simplify installation in tight spaces. The MIL-C-5015 connection interface ensures a secure, reliable electrical connection.

Installation and Setup

Proper mounting is critical for accurate readings. The 190501-10-00-CN comes with a plate stud M6x1 to M6x1 with a 3/8-24 adapter. Use the specified mounting torque of 4.5 N-m ± 0.6 N-m (40 in-lbf ± 5 in-lbf) to ensure a solid mechanical bond. The transducer can be mounted at any angle, offering flexibility in machine layout.

For best results, mount the transducer on a flat, clean surface. Avoid excessive cable lengths beyond 305 meters (1,000 ft.) to prevent signal degradation. The internal electronics are isolated from the case, so no special grounding precautions are needed.

Maintenance and Reliability

Routine inspection of the transducer and its mounting is recommended. Check for any loosening of the stud or damage to the cable. The 316L stainless steel case resists corrosion, extending service life in humid or chemical environments. The transducer can operate in 100% condensing humidity (non-submerged), making it suitable for washdown areas.

Because the 190501-10-00-CN has no moving parts, it requires minimal maintenance. Its rugged design reduces the risk of failure, contributing to lower lifecycle costs.

Compatibility and Integration

This Bently Nevada transducer is compatible with standard vibration monitoring systems that accept velocity inputs. The output bias voltage of 10.1 Vdc and dynamic impedance of <400 Ω allow easy interface with most data collectors and online monitoring systems. The MIL-C-5015 connector is a common industrial standard, simplifying replacement.
