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

Introduction to the 190501-01-00-CN

When rotating machinery fails unexpectedly, the consequences can be costly. The 190501-01-00-CN from Bently Nevada provides reliable velocity measurement to help you detect problems early. This Velomitor CT velocity transducer is engineered for industrial environments where accuracy and durability matter.

With a sensitivity of 3.94 mV/mm/s (±5%), the 190501-01-00-CN converts mechanical vibration into a clear electrical signal. Its frequency response spans 3.0 Hz to 900 Hz (±1.0 dB), covering typical machine vibration ranges. This makes it a dependable choice for condition monitoring programs.

Key Features and Performance Metrics

• 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 range 1.5 Hz to 1.0 kHz (90 to 60,000 cpm) ±3.0 dB.
• Temperature Sensitivity: -8% to +5% typical over operating temperature range.
• Transverse Response: Less than 5% of axial sensitivity.
• Amplitude Linearity: ±2% to 63.5 mm/s pk (2.5 in/s pk).
• Mounted Resonant Frequency: 9 kHz minimum (stud mounted, except quick disconnect).
• Output Bias Voltage: 10.1 Vdc ± 1.0 Vdc, Pin A referenced to Pin B.
• Dynamic Output Impedance: <400 Ω typical.
• Broadband: 0.229 mm/s (0.009 in/s) pk.
• Base Strain Sensitivity: 0.43 mm/s/μstrain (0.017 in/s/μstrain).
• Grounding: Internal electronics isolated from case.
• Maximum Cable Length: 305 metres (1,000 ft.) of cable (part number 02173006) with no signal degradation.

One standout spec is the broadband noise floor of 0.229 mm/s pk. This low noise level means the transducer can pick up subtle vibration changes, allowing you to identify developing faults before they escalate.

Real-World Applications

The 190501-01-00-CN is well-suited for monitoring pumps, motors, fans, and other rotating equipment. In manufacturing plants, it helps maintain uptime by providing continuous vibration data. For predictive maintenance teams, this transducer supports trend analysis and alarm management. Its rugged design also makes it suitable for harsh environments, including those with high humidity or magnetic fields.

Installation and Setup

Mounting the 190501-01-00-CN is straightforward. The mounting hardware option includes a 3/8-in 24 stud, and the recommended mounting torque is 4.5 N-m ± 0.6 N-m (40 in-lbf ± 5 in-lbf). The connection interface uses a MIL-C-5015 connector, ensuring a secure electrical link. The transducer can be mounted in any orientation, giving you flexibility in tight spaces. Always follow the manufacturer's installation drawing to ensure proper alignment and signal quality.

Maintenance and Reliability

Regular inspection of the transducer and its cable is essential for long-term reliability. Check for physical damage, loose connections, or corrosion, especially in humid or corrosive environments. Because the internal electronics are isolated from the case, the risk of ground loops is minimized. With proper care, the 190501-01-00-CN can provide years of accurate vibration data, reducing unplanned downtime and maintenance costs.

Environmental Durability

The 190501-01-00-CN operates in temperatures from -40°C to +85°C and can be stored from -40°C to +100°C. It withstands shock up to 5000 g pk and humidity up to 100% condensing (non-submerged). Its magnetic field susceptibility is less than 0.0068 mm/s/gauss at 50 gauss, 50-60 Hz. The case is made of 316L stainless steel, offering excellent corrosion resistance.
